These include: hyperthyroid individuals order anacin australia pain medication for a uti, individuals with cardiovascular disease order 525mg anacin amex pain treatment centers of america, hypertension cheap anacin on line pain medication for dogs with renal failure, or diabetes, and the elderly. Respiratory System: Hyperventilation, pulmonary oedema Digestive System: Nausea and vomiting, Nervous System: Headache, tremor, dizziness, weakness, cerebrovascular haemorrhage Adrenaline! The management of patients with leukaemia, lymphoma and malignancies who are receiving cancer therapy which causes elevations of serum and urinary uric acid levels. The appropriate dosage may be administered in divided doses or as a single equivalent dose with the 300 mg tablet. Prevention of hyperuricaemia in patients at risk of tumour lysis syndrome: For the prevention of uric acid nephropathy during the vigorous therapy of neoplastic disease, treatment with 600-800 mg daily for 2-3 days is advisable together with a high fluid intake. It is an inhibitor of xanthine oxidase, the enzyme responsible for the conversion of hypoxanthine to xanthine and of xanthine to uric acid, the end product of purine metabolism in man. Therefore, treatment with allopurinol should be discontinued immediately if a rash develops. Some patients with pre-existing renal disease or poor urate clearance have shown a rise in creatinine during allopurinol administration. In patients with hyperuricaemia due to malignancy, the vast majority of changes in renal function are attributable to the underlying malignancy rather than to therapy with allopurinol. Although the mechanism responsible for this has not been established, patients with impaired renal function should be carefully observed during the early stages of allopurinol administration so that the dosage can be appropriately adjusted for renal function. Bone marrow depression has been reported in patients receiving allopurinol, most of whom received concomitant drugs with the potential for causing this reaction. This has occurred as early as 6 weeks to as long as 6 years after the initiation of allopurinol therapy. Laboratory Tests: The correct dosage and schedule for maintaining the serum uric acid within the normal range is best determined by using the serum uric acid as an index. It may, on occasion be appropriate to measure a uric acid level in a patient on allopurinol in the intensive care unit. Drug/Laboratory Test Interactions Allopurinol is not known to alter the accuracy of laboratory tests. Subsequent adjustment of doses of mercaptopurine or azathioprine should be made on the basis of therapeutic response and the appearance of toxic effects. Thiazide Diuretics: Renal function may be more likely to deteriorate with the combination of allopurinol and thiazide diuretics and, in patients on thiazide diuretics, allopurinol dosage levels should be more conservative. Amoxicillin: An increase in the frequency of skin rash has been reported among patients receiving amoxicillin concurrently with allopurinol compared to patients who are not receiving both drugs. Cyclosporin: Cyclosporin levels may be increased during concomitant treatment with allopurinol. Monitoring of cyclosporin levels and possible adjustment of cyclosporin dosage should be considered when these drugs are co-administered. Musculoskeletal System: Exacerbation of gout during initial treatment, arthralgias Haematological System: Eosinophilia and mild leukocytosis or leukopaenia Allopurinol! Store at room temperature 15-30°C; protect from light Compatible with: normal saline, D5W, D10W, Glucose and Sodium chloride, Hartmann’s. Do not mix with other medications – many medications with precipitate if mixed with aminophylline. Aminophylline should be ceased if the patient develops significant renal impairment. Theophylline directly relaxes the smooth muscle of the bronchial airway and pulmonary blood vessels, thus acting mainly as a bronchodilator and smooth muscle relaxant. It has also been demonstrated that aminophylline has a potent effect on diaphragmatic contractility in normal persons and may then be capable of reducing fatigability and therapy improve contractility in patients with chronic obstructive airway disease. Underlying seizure disorders (unless receiving appropriate anticonvulsant medications). Serious side effects such as ventricular arrhythmias, convulsions or even death may appear as the first sign of toxicity without any previous warning. A serum concentration measurement is the only reliable method of predicting potentially life-threatening toxicity. Theophylline products may cause or worsen arrhythmias and any significant change in rate and/or rhythm warrants measurement of a serum level and consideration of cessation of the drug. Nervous System: Headaches, reflex hyperexcitability, muscle twitching, clonic and tonic generalized convulsions. Administration via a central line is preferred Store at room temperature; do not refrigerate. Hypotension should be treated by vasopressor drugs, positive inotropic agents, and volume expansion. Additional measures including drug therapy and/or temporary pacing may be required if bradycardia does not resolve. Rare cases of fatal hepatocellular necrosis after treatment with amiodarone have been reported. Like all antiarrhythmic agents, amiodarone may cause a worsening of existing arrhythmias or precipitate a new arrhythmia. There have been reports of acute-onset (days to weeks) pulmonary injury in patients treated with amiodarone. Findings have included pulmonary infiltrates on X-ray, bronchospasm, wheezing, fever, dyspnea, cough, haemoptysis, and hypoxia. Laboratory Tests: Consider measurement of thyroid function as a baseline (if not measured previously). Drug/Laboratory Test Interactions Amiodarone alters the results of thyroid-function tests, causing an increase in serum T4 and serum reverse T3, and a decline in serum T3 levels. Antiarrhythmics: in general, any added antiarrhythmic drug should be initiated at a lower than usual dose with careful monitoring. This drug is not recommended for use during the acute recovery phase following myocardial infarction. Amitriptyline has been reported to produce arrhythmias, sinus tachycardia, and prolongation of the conduction time. Nervous System: Seizures; hallucinations; ataxia; tremors; peripheral neuropathy; numbness, tingling, and paraesthesias of the extremities; extrapyramidal symptoms; drowsiness. Amlodipine is a peripheral arterial vasodilator that acts directly on vascular smooth muscle to cause a reduction in peripheral vascular resistance and reduction in blood pressure. Since amlodipine besylate is extensively metabolized by the liver and the plasma elimination half-life (T½) is 56 hours in patients with impaired hepatic function, caution should be exercised when administering amlodipine besylate to patients with severe hepatic impairment. Cardiovascular System: Arrhythmia (including ventricular tachycardia and atrial fibrillation), bradycardia, chest pain, hypotension, peripheral ischemia, syncope, tachycardia, postural dizziness, postural hypotension, vasculitis. Digestive System: Anorexia, constipation, dyspepsia, dysphagia, diarrhoea, flatulence, pancreatitis, vomiting, gingival hyperplasia. Nervous System: Hypoesthesia, neuropathy peripheral, paraesthesia, tremor, vertigo.
With practice it’s easier to tell if this trickle indicates a good enough insertion into the vein order anacin 525mg without prescription back pain treatment yahoo. Injecting a tiny bit of air (about an eighth-inch) with the heroin is harmless but if the user is nervous about this the syringe could be tilted so the air floats to the other end trusted 525 mg anacin deerfield beach pain treatment center. From personal experience a quarter- inch (about 10 units) of air being injected with heroin is harmless but there’s no need to make a habit of injecting air purchase anacin cheap online kearney pain treatment center. With a little practice the user can be pretty sure the heroin is going in the vein without first checking for blood but still checking for a burning feeling where it’s being injected or a blister forming. When trying heroin for the first time the user, of course, starts out with a tiny bit to see how his or her body reacts to it. As with pain pills sometimes the stomach gets queasy when the body isn’t used to it. In the case of an overdose the only thing I know to do is to keep the person up and walking around to keep the heart going. If medical attention is needed I’m pretty sure the paramedics use a drug called “narcan” which blocks the effects of opiate narcotics like heroin. Heroin is put on aluminum foil and heated from the bottom and allowed to run down the foil, if possible, while inhaling the smoke. The user can be on heroin for a few days straight (a quarter-gram or so per day) and stop cold- turkey with no symptoms of physical withdrawl whatsoever. Often it contained alot of other agents like pieces of broken glass, pieces of foil, dirt, wood, metal, mannitol, lactose, maltose, sand, you get the idea. The first stage of the process I used was to make sure the diacetylmorphine (heroin) I received was totally converted to a soluable hydrochloride salt. The heroin I usually received was a brown powdered heroin, sometimes off white, very little vinegar smell. The way I made sure it was a soluable salt was to drop enough 28% hydrochloric acid to make it wet. This insured that I would not waste any of the available drug, but would remove most if not all of the cut. First weigh out one gram of heroin from the stock you received from your supplier. Next add 5 ml distilled water, place your thumb over the end and carefully shake to dissolve all that will dissolve into the water. Using a eye dropper, remove and transfer as much of the liquid to a fresh test tube leaving the solids behind. Slowly add, with the eye dropper, one drop at at time, ammonium hydroxide (water clear household ammonia) until the white precipitate ceases production. Now add 100 ml ethyl ether (read the text on getting ethyl ether from Chapater 3: Making Meth) to a 150 ml beaker. Dump the milky liquid into the ether and stir briskly and allow the water to settle and collect on the bottom. Using a glass eye dropper, remove this water from the bottom of the beaker and dispose of. Now mix up a solution of 5ml 28% hydrochloric acid and 5ml distilled water and add this to the ether in the beaker. Stir briskly keeping as much acid/water suspended as possible for several minutes. Using a glass eye dropper, remove this water layer from the bottom of the ether and transfer to a glass petri dish. Slowly add small portions of sodium bicarbonate (baking soda) to the water/acid solution in the petri until you don’t notice any more bubbles being formed. Table salt is a by-product of the reaction and will not hurt you at all when injected. Place 100 mg of this powder in a test tube, add 10 cc sterile isotonic water for injection (available over the counter at drug stores) and heat to boiling. Transfer this liquid while still hot using a syringe (available over the counter at some drug stores) to a 10 ml rubber stoppered empty sterile ampoule (available over the counter at drug stores). To use this drug which is 10mg/ml, extract with a sterile syringe as much drug as you wish to use. Using heroin in this manner avoids the problems associated with “street use” and will keep your body healthy and safe, reducing the risk of disease and overdosage. When shooting up, locate the valve and inject either above it or below it, never into it. When you lift your finger, the valve will open and that’s when you know you found a valve. Use a big rubber band (used on most sling shots) because it is soft wide and elastic. When shooting in veins lower down on your arm move the torniquet below your elbow. The veins in your hand are more fragile and smaller then the other veins in your arm. Try to use smaller guage needle and inject much more slowly than you would in a a big arm vein. The reason for that is that you inject too fast, you put too much pressure on your delicate vein which can burst. Trying to inject against the flow will increase the chance of blowing out a valve, doing damage to your vein or wasting drugs. This will help prevent track marks, infections or abscesses, because when you get rid of dirt and germs on your skin you don’t jamm them into your body. Wash your hands if you can before touching your injection site, needle, cooker/spoon, cotton, and your drugs. Even though there may be unknown stuff in your drug, you still want to be as clean as possible and reduce any harm to yourself. Dental cotton is the best because it is made of very long, flexible, clean fibers, that will not break off and get injected into your vein. It also has a little hole in the center that helps protect the point of the needle. Dental cottons are also best because they are already rolled into a ball and you don’t have to handle them much, so there is less chance of breaking fibers or getting other stuff in your mix. Other filters, cotton balls, cigarette filters and Q-Tips may contain short, sharp, brittle fibers that can eaily break off and be injected along with your drug which can cause all kinds of bad shit, like infections, abscesses and clogged veins. Syringe exchanges provide dental cotton in convenient little plastic bags, which makes them easy to carry and keeps them clean. Some people say dental cotton is too small and put two or three of them together into the cooker.
Available experimental evidence demonstrates the key importance for conformity of inadequate individual knowledge and understanding discount 525mg anacin visa spine diagnostic pain treatment center. An important inference is that resistance to conformity or to interrogation pressures can be heightened by insuring that an individual is well informed of necessary facts and their implications purchase anacin 525mg online liver pain treatment home. Social Situation Tendencies toward conformity and conversion are heightened when an individual is with at least three other persons buy cheap anacin 525mg on line treatment for lingering shingles pain, when others are in -266- unanimous agreement and when their reactions represent only small departures from the position believed by the individual to represent his own convictions. Resistance is minimized by leading the individual away from his own position gradually by small steps. If the other individuals present are personally acquainted with the subject, and are persons whom he respects, additional conformity pressures are created. Furthermore, if the individual is required to act in his own name and is not required to commit himself to a position prior to the application of pressure, greater influence in the conformity direction can be exercised. A group situation tends to foster conformity, when the group is led according to a permissive groupcentered approach, when members are dependent on one another to obtain significant goals, when the situation calls for unanimous agreement among members, and when the group is cohesive. To create these conditions in life, it would be necessary to compose groups by careful selection to insure friendliness and responsibility among members, with all but one — the person on whom pressures are to be applied — agreeing unanimously in support of a position not greatly divergent from the position held by the critical person. It would appear that the best single antidote against conformity pressures is intimate acquaintance and thorough understanding of the issues involved. Although yet to be demonstrated experimentally, it also is probable that an individual would be aided in maintaining independence through understanding of conformity pressures. If not understood, they can operate "silently" to render an individual uncertain of himself, ready to follow others, and to capitulate to an interrogator. The Person A peisonality profile of the kind of individual who is least able to resist conformity pressures, and probably interrogation pressures as well, would include such characteristics as submissiveness, lack of self-confidence, lack of originality, lack of achievement motivation, desire for social approval, and being uncritical, conventional, and authoritarian. Conversion As with conformity, conversion is highest for individuals whose initial response regarding factual matters or attitudes is indefinite, -267- vague, and uncertain. Conversion further appears to be more complete for individuals who resist conformity pressures for a longer time. Unlike conformity, however, conversion effects are heightened when capitulation occurs under leader-centered group pressure conditions. Resistance to conversion probably can be increased through insuring that the individual remains well informed and understands his own opinions and attitudes sufficiently well to express them clearly. Future Research Directions A number of limiting factors make generalizations from laboratory situations to life difficult. Real Life Situations Laboratory situations are relatively bland as far as involvement is concerned, at least in comparision with lifelike settings where the personal stakes connected with conformity, compliance, and conversion are higher. Because of the limited investment a laboratory situation usually evokes in an individual, direct or absolute comparisons between results obtained in it and actual life settings are likely to be treacherous. There is a need for the type of research that provides the experimenter with the opportunity to control and manipulate variables under realistic operating circumstances. Current knowledge of relevant variables should make it possible to design experiments for lifelike settings with a minimum of trial and error. Significant Issues Many of the experiments reviewed in this study have employed tasks requiring adjustments of individuals under conformity or conversion conditions that are extremely artificial. As a result, conformity or resistance may develop under conditions that bear little resemblance -268- to actual situations. Future laboratory investigations can benefit from employing tasks that arouse deeper personal commitment and stronger group loyalties. Empiricism and Intuition Even a cursory examination of the principal reports summarized here shows that much of the work in this area has been designed according to empirical understanding, intuition, and "hunch. Such theoretical statements can serve to bring order to an otherwise chaotic field of endeavor. Single Variable Designs Results from more recent experiments give substantial support to the view that conformity, compliance, and conversion are complex matters of adjustment that occur when a host of circumstances, rather than a single factor, are favorable. Critical factors include the nature of the task, the circumstances of the situation within which the behavior occurs, and the characteristics of the individual on whom pressures are exerted. Each possible source of influence needs to be varied simultaneously within the design of a single experiment, if we are to obtain a more nearly accurate picture of the dynamics of conformity. In terms of present understanding, it can be stated that the interaction of sources of influence is not additive, but that true interaction among variables occurs. Replication experiments are needed to insure that conclusions from single studies will stand. Conversion Over 90 per cent of work in this area has been concerned with conformity, yet the conditions under which changes induced by conformity -269- pressures extend into future behavior are of critical concern. For the most part, they represent an extension of the conditions already used in studying conformity to secure measurements of the residual effects of conformity pressures. Great progress in the understanding of both conformity and conversion phenomena may be expected from investigations designed to measure the persistence of conversion over time. Group discussion, decision, public commitment, and perceived unanimity as factors in the effectiveness of "group decision. An experimental investigation of the effectiveness of the "big lie" in shifting attitudes. Screening tests, lie scales, observational and interview procedures have all been devised with the primary intent of unmasking the potentially or actually disturbed individual who masquerades behind a front of defensiveness and superficial social conformity. Murphy (65) has written an excellent history of malingering and has shown that the problem of simulation has been present since Early Greek and Biblical times. Although the simulation of psychosis or of epilepsy has a long history, more attention has been given in the past to the feigning of diseases of single organs, and the development of laboratory techniques which would differentiate the sick from the well. The malingerer, on his part, has shown amazing resourcefulness in keeping abreast of the literature and in devising counter counter-measures. The simulation of mental illness by captured prisoners of war is a potential, and perhaps effective, technique for evading interrogation. In almost all cultures, the mentally ill person cannot be held accountable for his actions, is considered incompetent, and is not -277- expected to give a rational account of himself, his past, or his environment. The prisoner of war, faced with coercive interrogation, and reluctant to betray his country and friends, might choose this as an honorable alternative which favors self-preservation. Certainly this has become more frequent among persons charged with serious crimes in courts of law. This chapter is not concerned with the moral or ethical aspects of this problem, but rather is directed toward understanding how malingering may become a factor in situations involving the interrogation of a resistant source by a captor. Because of the focus of interest, it seems feasible to limit the scope of this chapter to the feigning of those illnesses which would render the person mentally incompetent. Although a person may malinger a paralysis of the arms or legs, blindness, or a low back pain, none of these symptoms would make it impossible for him to testify or reveal information. However, psychosis, mental deficiency, or amnesia would more than likely lead an interrogator or examiner to the conclusion that the person is not a reliable source of information who can be expected to report events accurately and realistically.
That is not necessarily the case for a biologically active molecule cheap anacin 525 mg overnight delivery advanced pain treatment center mason ohio, but without further precautions a simple summation of fragments may lead to erroneous conclusions cheap 525mg anacin mastercard pain tmj treatment, as e cheap anacin amex breakthrough pain treatment guidelines. In the world of bioinformatics there has always been the notion that databases holding e. Many compound databases were either prohibitively expensive for academic use or simply not accessible (e. It is a database of drug-like small molecules, with bioactivities abstracted and curated from available scientific literature and patents. As with all databases care should be taken as errors tend to propagate; we noticed several errors ourselves, such as wrong bioactivity data, wrong structures, all probably inevitable in such huge data compilations. In fact, this is the consequence of the transformation from information in published documents such as scientific papers towards data storage. This involves the human mind and possible interpretation errors, the conversion of flat text into structured data such as in databases, and potentially many more ‘conversion’ errors. A better approach would be to remove these intermediate steps of flat text publishing and data extraction and instead make the data directly available in structured format. However, when data is entered in standard databases, most of the context that would normally be provided in an article is lost. Some data providers attempt to offer some context as extra fields in database tables. However, this is done fairly ad-hoc and not in a standardized manner, and these additions therefore lack any real meaning. These shortcomings are increasingly realized nowadays, but aligning and integrating proprietary and public 221 Chapter 7 data sources into a single system is a difficult and time consuming task. Hence it does not come as a surprise that duplication and redundancy are common across companies, institutes and academic laboratories. The members involved in this consortium (both from academia and industry) aim to create an open platform, Open Pharmacological Space, which will be freely accessible for knowledge discovery and verification. Most potent hit compound from the A2A substructure-based screening (Chapter 5) and two examples of hits with roughly the same affinity identified in 1 2 the structure-based screening studies of Katritch et al. In the early phases of the research (2006, 2007) no other structures than rhodopsin were available. That all 222 General Conclusions & Perspectives changed with the elucidation of the 3D structure of the β2-adrenergic receptor, 3 followed by a number of other receptors. Interestingly, some of these receptor structures have been successfully used for virtual screening, by docking commercially available compounds into the ligand binding site and prioritizing them on their energy 1,2,4 score. High ‘hit rates’ were observed and chemical diversity in these hits was also significant. This might suggest that ligand-based methods are obsolete; however, we showed that the hits from the ligand-based approaches are also viable, and, most importantly, different from the ones found in the structure-based screening (see Figure 1). In fact, we also benefitted from the structural knowledge obtained in recent years. Another option would be to feed the compounds stemming from a structure-based search into the ligand-based approach we took in Chapter 6, i. It would be interesting to see whether the combination of the two approaches would also allow us to further expand on all pharmacological characteristics of new compounds. Currently, affinity is the almost exclusive determinant used, whereas ligand efficacy (i. Two recent computational papers are seminal in this respect, and they seem to define a new avenue for research. Shaw Research Institute embarked on long timescale molecular dynamics calculations by using a supercomputer (Anton) that speeds up these lengthy calculations by orders of magnitude. In the second paper the activation mechanism of the β2-adrenergic receptor was studied, taking advantage of 7 both agonist- and antagonist-bound structures. There appears to be a relatively good match between protein dynamics at the microsecond scale and pharmacological 223 Chapter 7 observations, such as ligand association and dissociation kinetics and the interconversion between an active and an inactive conformation. However, recently, government-sponsored initiatives, private charities and academic institutions have emerged that challenge this dominant position. Examples of privately-funded foundations that have a significant influence on global drug research and development today are e. The Bill & Melinda Gates foundation is a charity that invests heavily in research and development of new vaccines, drugs, and diagnostics. The Cystic Fibrosis Foundation supports cystic fibrosis research and clinical trials through grants and specialized treatment centers. Research efforts funded by the foundation resulted in identification of the gene responsible for cystic fibrosis as well as several therapies, both approved and in the pipeline, for the treatment of cystic fibrosis. An important industrial partner for the Foundation is Vertex Pharmaceuticals, which is developing several small molecule drugs for this life- threatening condition. Fox Foundation is another example of an institution with significant influence focused at a specific disease. The foundation is dedicated to finding a cure for Parkinson’s disease by funding research efforts and the 224 General Conclusions & Perspectives development of therapies. In addition to aforementioned charitable foundations, academic institutions are also emerging as important players in the drug discovery and development field. A typical example with significant breadth is the Vanderbilt center for neuroscience drug discovery. This institute aims to bring its findings beyond the proof-of-concept stage and move towards advanced toxicity testing in animals in at least three of their programs before beginning clinical trials. In conclusion new ways of ‘drug hunting’ are being explored, and I am happy to have been actively involved in one of such initiatives. The emerging ‘open source’ approach to drug discovery would be the logical consequence of trends described in this thesis, such as the use of publicly accessible databases, the availability of open source software, and an increased data sharing between public and private partners. It would have the added benefit of a further maturation of the cheminformatics field. Structure-Based Discovery of Novel Chemotypes for Adenosine A2A Receptor Antagonists. The Significance of G Protein-Coupled Receptor Crystallography for Drug Discovery. Definition of the G Protein-Coupled Receptor Transmembrane Bundle Binding Pocket and Calculation of Receptor Similarities for Drug Design. Some thoughts on drugs and drug discovery per se and how developments in informatics and computer science offer new opportunities, were brought forward. In chapter 2 we reviewed a number of computational strategies to dissect molecules into sets of constituting atoms, leading to fragments of different nature. The reason for doing these, often computationally intensive, operations is found in the wealth of information that can be gleaned from such analyses. Virtual and real-world compound libraries can be mined for their diversity and/or similarity. Furthermore, occurrence and co- occurrence of fragments may suggest new directions into chemical space. This may help the medicinal chemist in designing safer or more selective lead compounds. Conversely, desired activities can be linked to fragments, and such information may be a decisive factor in a successful medicinal chemistry program.
It is poorly soluble cheap 525mg anacin with mastercard pain tmj treatment, and the 50-mg intravenous preparation typically also contains benzyl alcohol (0 purchase 525mg anacin overnight delivery pain relief treatment center llc. Trade names for teniposide include Vehem generic 525mg anacin visa neuropathic pain treatment drugs, Vehem-Sandoz, Vumon and Vumon Parenteral (Royal Pharmaceutical Society of Great Britain, 1999; Swiss Pharmaceu- tical Society, 1999). The methods for the analysis of teniposide in various matrices include high-performance liquid chromatography, thin-layer and paper chromatography and radioimmunoassay (Kettenes-van den Bosch et al. During early clinical trials for cancer chemotherapeutic use, podophyllotoxin itself proved to be too toxic, and, in the 1960s, two epipodophyllotoxins, teniposide and etoposide (see monograph, this volume), were described (Keller-Juslén et al. Teniposide is used in the treatment of adult and childhood leukaemia, typically at doses of 30–50 mg/m2 per day for five days or three doses of about 200 mg/m2 over seven days. The drug is also used in the treatment of brain tumours in adults and neuroblastoma in children. Teniposide is active against a number of other tumour types, including small-cell and non-small-cell lung cancer, lymphomas and bladder cancer. It is used much less commonly than the related drug etoposide (Giaccone, 1992; Giaccone et al. Studies of Cancer in Humans This section summarizes only studies in which tepinoside was given without agents with known or suspected leukaemogenic properties. In studies in which patients were treated with both tepinoside and etoposide, the authors used various conversion factors to derive an ‘equivalent dose’ of etoposide from that of teniposide. The conversions were based, however, on the therapeutic effects rather than on meta- bolic considerations. Of 60 patients in whom complete remission was achieved, 14 suffered a bone-marrow relapse. Thus, the frequency of conversion from acute lymphoblastic leukaemia to acute myeloid leukaemia was 3/60. The authors noted that 45 children with non-T-cell acute lymphoblastic leukaemia were treated between 1981 and 1984 with a regimen that did not include teniposide and cytarabine, and no cases of acute myeloid leukaemia were observed at relapse. Tests for myeloid marker cells had not been performed at initial diagnosis in any of the three cases reported. No appropriate comparison of leukaemia risk between the two treatment groups was made. The median interval between the diagnoses of acute lymphoblastic leukaemia and acute myeloid leukaemia was 40 months. Six cases were acute myelo- monocytic leukaemia, eight were acute monoblastic leukaemia, three were acute myeloblastic leukaemia, one was acute megakaryoblastic leukaemia, one was acute myeloid leukaemia and two were acute undifferentiated leukaemia. In four patients, acute myeloid leukaemia developed after relapse had occurred, and these were not included in the analysis. In the analysis of leukaemia risk, the doses of teniposide and etoposide were weighted equally since the potency of teniposide in vitro—10 times that of etoposide—is offset in vitro by extensive protein binding, resulting in 10 times less unbound active drug. The analyses indicated the importance of the schedule and frequency of epipodophyllotoxin treatment in determining the risk for acute myeloid leukaemia (see Table 1). In a combined analysis of 12 trials in patients with various primary tumours who developed acute myeloid leukaemia after treatment with epipodophyllotoxins (Smith et al. The p values for homo- geneity of the risk for leukaemia across the cumulative dose strata were 0. In one of the trials, 251 patients with primary acute lymphoblastic leukaemia received only teniposide as three courses of 165 mg/m2 for two days, for a cumulative dose of 990 mg/m2, correspon- ding to a moderate cumulative dose of epipodophyllotoxin. Thus, the data provide no support for an effect of the cumulative dose of epipodophyllotoxins on leukaemogenic activity, at least not within the cumulative dose range encompassed by the monitoring plan. It is also not clear which patients received teniposide and which received etoposide. The patients in these series received treatments similar to those in the study by Pui et al. The mean follow-up period beyond one year of survival for the entire cohort was 7. Twenty-six cases of secondary leukaemia occurring after diagnosis of the initial childhood neoplasm between 1940 and 1983 were each matched with up to four controls for sex, histological type of first cancer and age at first diagnosis. In addition, the controls had to have survived free of any second primary neoplasm for at least as long as the interval between the first primary neoplasm and secondary leukaemia in the corresponding case. Of those patients receiving chemotherapy (69% of cases, 55% of controls), 77% had received alkylating agents, 51% antibiotics, 54% antimetabolites, 97% vinca alkaloids and 30% epipodophyllotoxins. Ten patients with leukaemia had received epipodo- phyllotoxins during their treatment: nine had received teniposide and one had received etoposide. Multivariate analysis of the relative risk for leukaemia (adjusted for active bone marrow radiation dose and exposure to alkylating agents) according to the total dose of epipodophyllo- toxins estimated by either method showed evidence of a trend (p = 0. The controls had to have survived without a second cancer for at least as long as the interval between the diagnosis of Hodgkin disease and leukaemia in the case patient. Controls were matched to the case patient on cancer centre, sex, date of birth and date of diagnosis of Hodgkin disease. In multivariate analyses, all of the relative risks were adjusted for mechlorethamine dose, lomustine, dacarbazine, cyclophosphamide given in combinations, teniposide, interaction between cyclophosphamide and teniposide, splenectomy and number of episodes of chemotherapy. In these analyses, treatment with teniposide (median dose, 300 mg; seven cases, six controls) did not increase the risk for leukaemia (relative risk, 0. Since only one case patient and two controls received teniposide without cyclophosphamide, however, the independent effect of teniposide on the risk for leukaemia could not be assessed reliably. Treatment with cyclophosphamide alone was not significantly associated with an increased risk for leukaemia. The combination of cyclophosphamide and teniposide, which had been used in six patients who developed leukaemia and four controls, was associated with a strongly increased relative risk (125 000; p = 0. Studies of Cancer in Experimental Animals No data were available to the Working Group. Risks for acute myeloid leukaemia in children treated for primary neoplasms with epipodophyllotoxins, in relation to dose Dose of epipodophyllotoxin No. After intravenous administration of 50–200 mg/m2, the disposition of the drug typically fitted a two-compartment model, with terminal elimination half- times of 6–10 h (Rossi et al. Tri- exponential decay has also been reported, with terminal half-times of 26 h after admin- istration of [3H]teniposide (Creaven & Allen, 1975), 20 h after a low intravenous dose of 30 mg/m2 (Canal et al. The distribution volume of teniposide in these studies was 8–30 L/m2, indi- cating that the drug is distributed mainly in the extracellular fluid compartment, with a total plasma clearance rate of 7–17 mL/min per m2 and a low renal clearance rate of 0. The pharmacokinetics of teniposide was linear up to 1000 mg/m2, the highest dose tested (Holthuis et al. After intravenous infusion of 150 mg/m2 over 24 h in adults, the peak plasma concentrations were 4–12 μg/mL (D’Incalci et al. In children receiving 450 mg/m2 over 72 h, 10 of 11 values were between 4 and 13 μg/mL, and the remaining value was 30 μg/mL (Rodman et al. Considerable variation in the pharmacokinetics of teniposide between patients has been described, which may explain some of the variation in the pharmacodynamics of the drug. This resulted in a > 50% increase in systemic exposure, as measured by the steady-state plasma concentration (15. In children given teniposide, the main metabolite in serum and urine was reported to be the hydroxy acid, formed by opening of the lactone ring; the cis-isomer, which may be a degradation product formed during storage, was also detected.

In our opinion that pharmaceutical organizations to develop and implement a quality management system must: an analysis of the existing quality control of pharmaceutical products and services; conduct a situational analysis and diagnosis of problems of quality management; objectives and responsibilities; determine resource capabilities and resource requirements; motivate employees of the organization; develop a program introduction and implementation of quality management system; build a system of training for the intended principle anacin 525 mg mastercard new pain treatment uses ultrasound at home. For domestic Pharmaceutical Manufacturers such a step makes it possible to consolidate its position not only in domestic but also in foreign markets discount anacin online visa blue ridge pain treatment center harrisonburg. At the same time buy anacin overnight pain treatment centers of america carl covey, domestic companies often performed audit formally, mostly just to meet the requirements of supervisory authorities. As information database of research were used laws of Ukraine, which are published in the official sources, and also the resources of Internet network and materials published in scientific and professional literature. Accordingly, there are not mandatory legal regulations to determine the order and rules of audit of quality systems, determination of requirements to auditors and the required reporting. We plan to conduct studies to comparative analysis of mentioned standards requirements, and determine the status of audits on domestic enterprises of different ownership, product range, magnitude and complexity of the of production processes. For our study, we chose the most acceptable variant to obtain information - a sociological survey to the representatives of company. The respondents, that the heads of quality control department will come forward, will be offered to fill an application form, that will contain questions about the form of audits, the number of involved auditors and their qualifications, frequency of audits, audit complex of documents, applicable auditing methods and so on. The sociological survey is planned to conduct by using of software products like Google of Form and Survio. The analysis of existing legal and regulatory requirements to the system found that the regulation of the formation of such systems and their individual processes, in particular - internal audits provided only by general provisions. Is also marked that the certain shortage of methodical literature and scientific publications on these questions. Accordingly, our research aimed at determining the best approaches to the organization of effective audits, as well as the assessment of internal audits proceedings in domestic companies. Jordan is considered a pioneer in the Arab world from the perspective of the pharmaceutical industry, since the first pharmaceutical factory was founded in Jordan in 1962. Since then, the volume of the pharmaceutical industry in Jordan has increased significantly: аs of January 2016 are 17 pharmaceutical companies, pharmaceutical manufacturers. In Jordan, the dynamically developing production of pharmaceutical and cosmetic products, 70% of which are exported to other countries. Cosmetic products based on Dead Sea salts and dirt are exported to many European countries. In Jordan, there is no local manufacturing capacity for certain therapeutic groups of drugs – such as cancer drugs, vaccines. Our research has focused on the issue of theoretical analysis of pharmaceutical industry in Jordan. We used empirical methods: observation and comparison; and methods of experimental and theoretical: logical analysis, the hypothetical synthesis of theoretical generalizations. Local pharmaceutical manufacturers carry out contract manufacturing for major international pharmaceutical companies, but now it is less than 5% of the revenue of the pharmaceutical sector as a whole. Major pharmaceutical companies, which owns a number of factories producing medicines in Jordan: The Arab Pharm. Pharmaceutical company provides detailed information on the drug, which comprises the chemical structure, pharmacological and chemical properties, classification according to the Anatomical Therapeutic Chemical Classification regarding the therapeutic activity of the drug and its active ingredients on the organs or organ systems, to which they affect Conclusions. Therefore, this process can lead to the prices on the products will be higher on average than in some neighboring countries (such as in Egypt). In order to pass the accelerated registration procedure, the drug should be included in Rational Drug List Jordan. If the drug is approved for Rational Drug List, public hospitals can send their requests to the Department of Procurement Jordan. Patients in this case pay the international price of the drug, which is fixed by a pharmaceutical company in the country of origin. Currently, in Ukrainian pharmaceutical business facilities insufficient attention paid to audit quality, which conducted by the organization itself. However, it is internal audits first of all make it possible to determine as required and accepted at the discretion of the procedure and planned activities properly composed, performed and to prevent adverse effects. Internal Audit is the highest form of management control quality management system of Pharmacy company. Internal audit is an important management function, which covers accounting, financial analysis and monitoring, evaluation and comparison actual results achieved with the goal and objectives of pharmaceutical companies. The research of our thesis focused on the analysis of the audit of the pharmaceutical company, drafting the audit plan for example Chemical- Pharmaceutical Factory «Червона Зірка». Materials and methods: the theoretical analysis of scientific literature, periodic publications, experimental and theoretical methods: logical analysis, the hypothetical synthesis of theoretical generalizations. Audit regularly monitors the activities of all facilities management, identifies the causes of deviations from the standards deviations from the objectives set for the specific object, promotes efficient elimination of the violations. Built-in mechanisms for continuous optimization of processes within the Quality Management System can not only continually reduce risks to product quality and increase the level of satisfaction of requirements but also to reduce unproductive costs, positive impact on costs. Thus, the introduction of the Quality Management System is a rational step towards the strengthening of the market position and further business expansion. Company audit as a function of business management – a strict regulation of activity, the definition of duties and responsibilities of specialists, qualification requirements, relationships between departments and personnel. We plan to develop recommendations to improve the audit process to minimize errors, analyze and identify inconsistencies, recommendations to eliminate inconsistencies as long as they did not affect the quality of products, and therefore also the reputation of the company. Research of this issue provides a material optimization of audits and use this information in the future not only for troubleshooting, but also to be able to predict and prevent. Such systems involve significant changes approaches to management of the organization, focusing all kinds of internal activities (business processes) to enhance guarantees of regulations and requirements and expectations regarding products and services. We used empirical methods and theoretical methods: logical analysis, the hypothetical synthesis of theoretical generalizations. Internal audit should become a permanent process of supplying information for the management of the organization, so you need to attract appropriately trained auditors. Significant personal role as auditors and experts in quality, since they affect the methods and techniques of auditing and performance. Auditors should ensure trust and ease in communication and show understanding explanations given on the facts discovered during the audit. In our thesis work is planned to analyze the impact of personal qualities of the auditor on the principles, methods and ways of auditing, to make the expanded criteria for personality traits to be met by the auditor and propose a method of checking compliance with those criteria. The success and competitiveness depend on competent management decisions and the level of competence of the personnel that directly affects the quality of the end product of each company. High requirements are put forward for the competence of personnel who are engaged in various kinds of control. The auditors should pass appropriate training, traineeship and certification, maintain and improve their competence in this field of activity. The aim of our research was the development of the internal auditors training program and evaluation of their competence. As a result of conducted research a program for internal auditors training and assessing their practical work at the pharmaceutical company has been developed, which includes: selection plan (determination of the necessary professional skills and knowledge of potential auditors; criteria for evaluation and ranking of candidates (assessment of professional knowledge of candidates for auditors and their expertise rating on a 5- point scale); training program for internal auditors (list of lectures and practical exercises followed by evaluation of acquired knowledge); program to improve knowledge and skills (development plan); quality control program of internal auditors work after conducting audits at the enterprise (used the method of units workers questioning where the internal audit carried out). The program developed can be used in the preparation of internal auditors in the pharmaceutical enterprises. It allows assessing the skills and knowledge of potential auditors and train them to use the knowledge gained in practice.
