2 EXPERIMENTAL 2.1 HPLC -UV ASSAY METHOD FOR SILDENAFIL 41. Adverse reactions were mild to moderate in nature and the incidence and severity increased with dose. 4.9 Overdose In single dose volunteer studies of doses up to 800 mg, adverse reactions were similar to those seen at lower doses, but the incidence rates and severities were increased. Doses of 200 mg did not result in increased efficacy but the incidence of adverse reactions headache, flushing, dizziness, dyspepsia, nasal congestion, altered vision ; was increased. In cases of overdose, standard supportive measures should be adopted as required. Renal dialysis is not expected to accelerate clearance as sildenafil is highly bound to plasma proteins and not eliminated in the urine. 5. 5.1 PHARMACOLOGICAL PROPERTIES Pharmacodynamic properties Pharmacotherapeutic group: Drugs used in erectile dysfunction. ATC Code: G04B E proposed ; Sildenafil is an oral therapy for erectile dysfunction. In the natural setting, i.e. with sexual stimulation, it restores impaired erectile function by increasing blood flow to the penis. The physiological mechanism responsible for erection of the penis involves the release of nitric oxide NO ; in the corpus cavernosum during sexual stimulation. Nitric oxide then activates the enzyme guanylate cyclase, which results in increased levels of cyclic guanosine monophosphate cGMP ; , producing smooth muscle relaxation in the corpus cavernosum and allowing inflow of blood. Sildenafil is a potent and selective inhibitor of cGMP specific phosphodiesterase type 5 PDE5 ; in the corpus cavernosum, where PDE5 is responsible for degradation of cGMP. Sildenafil has a peripheral site of action on erections. Sildenafil has no direct relaxant effect on isolated human corpus cavernosum but potently enhances the relaxant effect of NO on this tissue. When the NO cGMP pathway is activated, as occurs with sexual stimulation, inhibition of PDE5 by sildenafil results in increased corpus cavernosum levels of cGMP. Therefore sexual stimulation is required in order for sildenafil to produce its intended beneficial pharmacological effects.

Patients arriving with signs or symptoms suspicious for myocardial infarction should be moved immediately to a patient care area. Such symptoms include not only chest pain but syncope, dyspnea, nausea, diaphoresis, upper abdominal pain, and upper body pain not clearly musculoskeletal in origin. The triage interview should be conducted together with immediate electrocardiogram ECG ; in a manner which does not delay rapid diagnosis of acute myocardial infarction AMI ; . ECG is the only method that such a diagnosis can be made early in the course of AMI. Thus, if beds are short, any available space should be used to obtain an ECG. Ideally, time of patient presentation to ECG should be less than ten minutes. The ECG should be shown to an emergency physician in order to immediately determine eligibility for advanced cardiac salvage techniques including fibrinolysis and angioplasty. Once seen, the emergency physician should initial and time the ECG, noting the presence or absence of changes indicative of acute myocardial infarction. For all patients, the standardized emergency chest pain order sheet should be brought to the emergency physician at the same time as the ECG, so treatment and further diagnostic tests can be quickly begun. Emergency nurses should be familiar with the orders on this sheet, and should initiate the treatment and diagnostic evaluation at their discretion. For example, all patients with suspected angina or myocardial ischemic equivalents should be immediately placed on a cardiac monitor, given supplemental oxygen following room air pulse oximetry, have intravenous access placed with blood tubes drawn, and have a portable chest radiograph performed. Except in rare circumstances, such patients should also have aspirin administered, even if on warfarin or aspirin already. Aspirin, a relatively benign treatment, has been demonstrated to reduce death from acute MI by 23 percent when used in a dose of 160 to 325 mg daily. In contrast, fibrinolysis, a much riskier treatment, reduces death by 25 percent.1 The only patients who should have aspirin withheld are those with severe concurrent bleeding or who have had anaphylaxis to aspirin in the past. Patients with anaphylaxis to aspirin may receive ticlopidine 250 mg twice daily ; , which has been demonstrated to reduce conversion from unstable angina to infarction by 46 percent.2 Nitrate use, due to inconclusive studies of mortality benefit, is ordered at the discretion of the emergency physician. Use of nitrates is contraindicated in right ventricular infarction and in patients taking sildenafil Viagra.

And iron chelation therapy may prevent or delay the onset of PH. In sickle cell anemia the incidence of PH is estimated to be 30-60% and a recent study has confirmed that PH determines a mortality risk in these patients.10 The mean pulmonary artery pressure is inversely related to survival with a 10 mmHg rise being associated with a 1.7-fold increased risk of death.11 Current oral treatment options are limited and include calcium channel blockers, prostacyclin analogs, endothelin-1 receptor antagonists, and thromboxane inhibitors.12 Calcium channel blockers are effective in only 30% of patients13 and are difficult to manage in hypotensive thalassemic patients. Endothelin-1 receptor antagonists can exacerbate elevated hepatic enzyme levels in thalassemia patents with liver disorders.14 Prostacyclin analogs improve clinical function in many patients, but the mode of administration subcutaneous or by continuous infusion ; can lead to serious complications as well as being very costly.15-17 The longterm efficacy of orally or inhaled prostacyclin analogs is yet to be established.18 Sildenafil citrate, a selective and potent inhibitor of cGMP-specific phosphodiesterase 5 PDE5 ; , which promotes smooth muscle relaxation in lung vasculature, has been used successfully in the treatment of primary and secondary PH.19-23 The efficacy of sildenafil has been previously demonstrated in chronic thromboembolic PH.24 One report of sildenafil utilized in a thalassemia intermedia patient with symptomatic PH documented improved function and significantly reduced PH over time.25 In this study the efficacy, safety, and tolerability of sildenafil were investigated in hemoglobinopathic patients with severe PH despite previous treatment with anticoagulant drugs, diuretics, cardiac glycosides, vasodilators, and blood transfusion therapy. The objectives of this study were to determine the efficacy of twice-daily dosing of sildenafil in reducing the tricuspid gradient and improving symptoms of PH, and to assess the safety and tolerability of this therapy regimen.

Dr Cameron said that the number of cases of malaria in South Africa had increased from 12 000 in 1995 to 50 000 in 1999. The increase could be attributed partly to climatic changes and resistance to certain drugs. Reporting methods have also become more accurate, so the number of cases might previously have been underreported, but there has been a real increase in the incidence of the disease, Dr Cameron said. Some 380 people died last year. It is possible that DDT will be used again in Mozambique. Its use there was stopped several decades ago, because 80% of the country's health budget came from donor funds, and donors refused to allow the use of DDT. Mozambique's earlier attempts to tackle the mosquito problem were hampered by South Africa's aggressive policy to the country during the apartheid era, when troops were flown in to fight the Mozambique government and it carried out air raids to destabilise the regime. The issues involved in tackling malaria are now being considered as part of a special development initiative on infectious diseases being undertaken jointly by the health departments of three countries: South Africa, Mozambique, and Swaziland. DISCUSSION Rapid progression to AIDS following acute HIV-1 infection has been described previously, as has the transmission of multi-drug-resistant viruses. The unique feature in this case is the convergence of the two phenomena: the transmission of a remarkably multi-drug-resistant HIV-1 variant and the extremely rapid clinical course to AIDS. It is incontrovertible that the duration of infection in this case cannot be longer than 20 months given his five negative HIV-1 antibody tests and normal absolute lymphocyte counts in the period prior to May 2003. It is possible that the transient febrile illness in early November 2004 was the manifestation of his primary HIV-1 infection, occurring approximately two weeks after a series of high-risk sexual contacts with multiple partners. If this were the case, then the duration of his infection would be about 4-5 months. That the detuned antibody test was positive is in line with an infection beyond the acute phase. Likewise, the relative sequence homogeneity in gag p17 and env gp120 V3 is consistent with, although not diagnostic of, recent infection. Thus, the totality of the evidence allows us to confidently say that this man has been infected for as little as 4 and not more than 20 months. This patient has been symptomatic with severe fatigue and weight loss, and his CD4 T-cell counts have been consistently below 80 mm3. He would therefore be classified as an AIDS patient. But is his rate of deterioration over 4-20 months considered remarkable? A couple of comparisons are quite revealing. First, an analysis of the data generated on acute seroconvertors in the Multicenter AIDS Cohort Study suggests that likelihood of progression to AIDS in 6 and 12 months to be 7 10, 000 and 45 10, 000, respectively A. Munoz, personal communication ; . Thus, by comparison, the index case would be in the top 0.5-percentile in terms of rapidity of disease. Second, an initial analysis of the database in the NIH Acute Infection and Early Disease Research Program revealed only 6 of 1709 cases with persistently low CD4 cell counts in early infection. Again, this comparison highlights our case as exceptional. Could the rapid clinical course be explained by the properties of the patient's unique HIV-1 variant? It is well documented that the presence of X4 variants of HIV-1 is associated with a more aggressive clinical course. This patient clearly has an X4 virus based on the SI phenotype in MT2 cells, and phenotypic studies unequivocally show viral tropism for both CCR5 and CXCR4. Despite the multitude of drug-resistance mutations, his virus grows well in vitro, and an assessment in the PhenoSense assay shows a replication capacity of 136% compared with wild-type viruses. These in vitro characteristics, coupled with the profound depletion of CXCR4 + T-cell populations in vivo raise the specter that this might be a particularly aggressive strain of HIV-1. That said, we are still unable to discount host factors that could have contributed to the clinical course and topamax.

Giving nitrates, such as nitroglycerin, to a patient suffering from chest tightness or chest pain may cause significant hypotension if the patient has recently ingested Viagra, Cialis or Levitra. Viagra sildenafil ; , Cialis tadalafil ; and Levitra vardenafil ; are selective phosphodiesterase type-5 PDE-5 ; inhibitors prescribed for erectile dysfunction. They increase cGMP in the corpus cavernosum thereby promoting blood flow to the cavernous spaces. Nitroglycerin also increases cGMP levels. The combined, additive effect produces a marked relaxation of vascular smooth muscle resulting in a significant drop in the systolic and diastolic blood pressure. This hypotensive effect has been shown in cohorts of healthy male volunteers, published case reports and in a case recently reported to the Maryland Poison Center. Nitroglycerin is therefore contraindicated in patients who are treated with PDE-5 inhibitors. Other nitrates such as isosorbide mononitrate, isosorbide dinitrate, pentaerythritol tetranitrate and sodium nitroprusside are also contraindicated. In addition, it is unclear how long after taking a PDE5 inhibitor it would be safe to give a nitrate. The preferred agents for chest pain in these patients would be opioid analgesics and antiplatelet agents. If hypotension occurs, promptly stop the nitrate therapy, place the patient in the Trendelenberg position, and institute aggressive fluid therapy. In patients with severe hypotension, vasopressors should be considered. Remember to ask about any previous PDE-5 inhibitor use when treating a patient with chest pain.

Sir: the irrationalities identified by Szmukler Psychiatric Bulletin, January 2000, 24, 6 ; suggest that serious incident inquiries serve a role well beyond the need to explain how or even why something `untoward' happens. Inquiries are, in fact, attempting to answer questions about fear, stigma, morality and personal responsibility, areas where rational inquiry has a poor record of satisfactory results. The folly of applying rational tools to irrational material becomes clearer when one considers the different perspectives and expectations of the agencies involved. To psychiatrists, inquiries are a quasi-legal form of local service audit, with powers to drive change far in excess of what may rationally be expected from a single case study. For the bereaved they serve a propitiatory role, the inquiry process helping families to make sense of the powerful emotions that accompany homicide. To the public at large, they provide a superficial way to soothe a fear that has troubled us since antiquity, and even more so in our individualistic, comfort-driven culture: `it could happen to me for no reason'. The idea of a `methodical' investigation of the causes of such a natural but irrational fear renders it more manageable. To the Government, inquiries into the minutiae of local service provision provide welcome distraction from the simple fact that the psychiatric services generally have always been neglected. The common theme of these irrationalities is the fear of mental illness. Many have suggested solutions to the problems of inquiries themselves Eastman, 1996; Buchanan, 1999 ; , but until we address the stigma-driven emotional responses that propel the current serious incident culture, or at least attempt to identify them, it seems that all shall lose and none shall have prizes.

The Market for Pharmaceutical Products and Material in Indonesia Dengue fever dengue haemorrhagic fever usually occurs in epidemic proportions during the peak season, starting in November and peaking in May. In 1998, 30, 000 cases were reported from cities and also from some rural areas. STDs remain a serious problem especially in high-risk groups and promotes the spread of HIV AIDS. Control is complicated by social and cultural attitudes towards these diseases and their interventions. As of January 1999, the cumulative number of reported AIDS cases was 227, of which 113 AIDS patients died. The progression rate seems to increase slowly doubling in more than two years. However this may be due to under-diagnosis or under-reporting. The health of women and children continues to be a problem. With five million pregnancies every year in Indonesia, more than 20, 000 women die annually during pregnancy and delivery. The high number of maternal deaths is especially a problem in rural areas with limited access to delivery by skilled attendants and an inadequate referral system. Almost 50% of women give birth without skilled attendants and 70% have no postpartum care during the six weeks following delivery. Many of the traditional infectious diseases of children have been controlled through immunization. Polio is close to elimination and current efforts focus on surveillance and final provincial Immunization Days campaigns. The last wild poliovirus isolated in Indonesia was in June 1995. 1999 represents the third year where national AFP surveillance has reached international performance targets. All surveillance indicators continue to improve. Routine EPI coverage has been maintained above 80% nationally with donor assistance; however, rates are falling in pocket areas. New immunization programmes, such as hepatitis B, are being implemented. Other initiatives are the School Immunization Month, TT immunization campaigns in high-risk areas, and improving injection practices. However, with decentralization of the health system, renewed efforts will be needed to ensure that immunization coverage is. Contributor Cindy H. Dubin believes that solubility remains at the forefront of drug delivery experts' formulation efforts and companies must continue to optimize the effect of drugs on the body through technologies that measure and determine rates of solubility as well as aim to overcome the challenges of low-soluble drugs.

We sought to compare the short-term impact of three different phosphodiesterase-5 PDE5 ; inhibitors on pulmonary and systemic hemodynamics and gas exchange parameters in patients with pulmonary arterial hypertension PAH ; . BACKGROUND The PDE5 inhibitor sildenafil has been reported to cause pulmonary vasodilation in patients with PAH. Vardenafil and tadalafil are new PDE5 inhibitors, recently being approved for the treatment of erectile dysfunction. METHODS Sixty consecutive PAH patients New York Heart Association functional class II to IV ; who underwent right heart catheterization received short-term nitric oxide NO ; inhalation and were subsequently assigned to oral intake of 50 mg sildenafil n 19 ; , 10 mg n 7 ; or 20 mg n 9 ; vardenafil, or 20 mg n 9 ; , 40 mg n 8 ; , or 60 mg n 8 ; tadalafil. Hemodynamics and changes in oxygenation were assessed over a subsequent 120-min observation period. RESULTS All three PDE5 inhibitors caused significant pulmonary vasorelaxation, with maximum effects being obtained after 40 to 45 min vardenafil ; , 60 min sildenafil ; , and 75 to 90 min tadalafil ; . Sildenafil and tadalafil, but not vardenafil, caused a significant reduction in the pulmonary to systemic vascular resistance ratio. Significant improvement in arterial oxygenation equally to NO inhalation ; was only noted with sildenafil. CONCLUSIONS In PAH patients, the three PDE5 inhibitors differ markedly in their kinetics of pulmonary vasorelaxation most rapid effect by vardenafil ; , their selectivity for the pulmonary circulation sildenafil and tadalafil, but not vardenafil ; , and their impact on arterial oxygenation improvement with sildenafil only ; . Careful evaluation of each new PDE5 inhibitor, when being considered for PAH treatment, has to be undertaken, despite common classification as PDE5 inhibitors.

Sildenafil, a selective phosphodiesterase 5 PDE5 ; inhibitor, has been on the market for weeks in the USA, having undergone an expedited review by the FDA and received its approval as an oral therapy for impotence. The reaction of the media and the general public has been explosive. Never before, it seems, has a new treatment medication received so much attention from the media, and within just a few weeks hardly anyone on the street is impervious to the VIAGRA phenomenon, the commercial name for sildenafil, what it is, and what it is used for. In the USA patients have rushed to clinics en mass requesting prescriptions, and it is estimated that one million males and an unknown number of females have already taken this medication. Europe, where sildenafil is not yet available, has not fallen short in terms of media coverage. In Spain, for example, countless television programmes handed their prime time over to sildenafil, despite the fact that there was no experience of using this medication. One can only begin to imagine the Byzantine discussions that took place in such forums that brought together writers, politicians, musicians, and other "experts" in the field of erectile dysfunction. Why has the appearance of sildenafil produced this reaction? For several reasons, one can guess. Firstly, sex is important in the life of many, if not most people. Secondly, sildenafil is an effective treatment that is easy to administer and if need be, conceal. It is important to keep in mind that before sildenafil, there were very effective but less user-friendly treatments for impotence. Thirdly, sildenafil is not only used by impotent men but also by men who want better erections. This reveals that many men feel insecure about the quality of their erection and the argument that most women are more interested in love and affection than in harder erections seems of little consolation to the average man who insists on more "potency.

Although sildenafil is effective in treating erectile dysfunction, its use is considered a relative contraindication in congestive heart failure CHF ; . This small trial assessed the safety and efficacy of sildenafil in patients with New York Heart Association classes II and III CHF and assessed effects on quality of life. 35 patients were included in a prospective, placebocontrolled, crossover trial for 12 weeks. Inclusion required a history of chronic erectile dysfunction and absence of ischaemia or nitrate use. The tolerability of sildenafil was established by monitoring the ambulatory blood pressure for 4 hours after a single 50mg dose. Improvement in erectile dysfunction was the primary end point.

Trimetazidine is an effective anti-ischaemic agent in patients with angina. 10 It significantly improves symptoms and exercise tolerance in patients with stable angina when used either as monotherapy or when combined with beta-blockers or calcium antagonists. In a study of stable angina patients with diabetes whose angina remained uncontrolled with conventional treatment, four weeks of treatment with trimetazidine resulted in improved exercise capacity and exercise duration, and a significant reduction in the number of angina episodes.11 It was well tolerated during the entire period of the study and no drug interaction was recorded. In another study of patients with ischaemic cardiomyopathy and depressed left ventricular function, trimetazidine produced significant improvements in left ventricular ejection fraction.12 It has also been shown that trimetazidine improves left ventricular function and functional capacity in diabetic patients with ischaemic cardiomyopathy receiving background anti-ischaemic therapy.13, 14 Given that diabetic patients are at risk of silent ischaemia, anti-ischaemic drugs with a long duration of action would be desirable to prevent cardiovascular events. It has been shown that the modified release formulation of trimetazidine trimetazidine MR 35mg taken twice a day ; offers a sustained anti-ischaemic and anti-anginal efficacy even at trough plasma concentration, twelve hours after the intake of the drug.15 Randomised controlled trials with hard endpoints will be required to show its benefit over conventional therapy. Patients with diabetes mellitus frequently have erectile dysfunction ED ; as a consequence of atherosclerosis, endothelial dysfunction and autonomic neuropathy. It is effective and safe for coronary patients to receive phosphodiesterase type 5 PDE5 ; inhibitors. However, PDE5 inhibitors are contraindicated in patients taking nitrate therapy and beta-blockers may further worsen ED. Trimetazidine, because of its mode of action and an absence of negative effect upon ED, is the drug of choice for the treatment of patients with CAD and ED who require treatment with PDE5 inhibitors. It has also been shown that trimetazidine plus sildenafil are more effective than nitrates in the control of myocardial ischaemia during sexual activity in patients with CAD.16 Putting the evidence together, trimetazidine may be a better therapeutic option over conventional anti-anginal therapies for CAD patients with diabetes complicated by ED.
