    Sildenafil, in doses ranging between 25mg and 100mg, has been FDA approved to treat erectile dysfunction. Your physician, based on the information you share with them (including your preference and previous use of the medication), will recommend a starting dose. They can also work with you to increase or decrease your dose based on effectiveness and toleration (i.e., titrate your dose). This enables you to achieve the desired effect while taking the least amount of medication. Sildenafil (Viagra), Cialis, and Levitra are part of a “family” of drugs called PDE-5 inhibitors. Sildenafil lasts up to 8 hours, which means it is in and out of your system faster than Cialis, which can last up to 36 hours. Some people prefer Sildenafil because if they experience side effects, even if minor, they would rather not experience them for up to 36 hours. On the other hand, some people prefer Cialis mainly because it lasts an extended period of time. VIAGRA 25 mg film-coated tablets Each tablet contains 0.834 mg lactose (as monohydrate).

    The primary indication of sildenafil is treatment of erectile dysfunction (inability to sustain a satisfactory erection to complete intercourse). Its use is now one of the standard treatments for erectile dysfunction, including for men with diabetes mellitus. Rare but serious adverse effects found through postmarketing surveillance include prolonged erections, severe low blood pressure, myocardial infarction (heart attack), ventricular arrhythmias, stroke, increased intraocular pressure, and sudden hearing loss. Care should be exercised by people who are also taking protease inhibitors for the treatment of HIV infection. Protease inhibitors inhibit the metabolism of sildenafil, effectively multiplying the plasma levels of sildenafil, increasing the incidence and severity of side effects. Those using protease inhibitors are recommended to limit their use of sildenafil to no more than one 25 mg dose every 48 hours. blocker (typically prescribed for hypertension or for urologic conditions, such as benign prostatic hypertrophy) at the same time may lead to low blood pressure, but this effect does not occur if they are taken at least 4 hours apart. Pulmonary hypertension is a progressive disease of diverse origin with devastating consequences in adults as well as in children. The phosphodiesterase 5 inhibitor sildenafil successfully lowers pulmonary vascular resistance. However, because of its poor enteral absorption, resulting in ineffective plasma concentrations, responses in infants and children are often erratic. We report the cases of two Caucasian boys, one born at term (case 1) and one aged 2.5 years (case 2), who had structural cardiac and pulmonary defects accompanied by symptomatic pulmonary hypertension. They received sildenafil enterally and sublingually and also intravenously in one of them. Plasma samples were taken at various time points to determine the plasma concentrations of sildenafil and its partially active metabolite. Sildenafil and In agreement with previous observations in adults, we found that sublingual sildenafil was more extensively absorbed in our two pediatric patients.
