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. Each year, millions of men rely on pharmaceuticals like Viagra and Cialis for their erectile dysfunction (ED), but they may not be the only ones facing dysfunctionalities. As the patents on these lucrative lifestyle drugs come to an end, price tags and bottom lines are expected to plummet. Viagra made by Pfizer and Cialis by Eli Lilly are phosphodiesterase type 5 (PDE5) inhibitors which break down cyclic guanosine monophosphate (c GMP). In a gross simplification, after sexual stimulation, an erection occurs through the release of nitric oxide (NO) which causes dilation of blood vessels due to an accumulation of (c GMP). Dysfunction occurs when c GMP conflicts with the NO vasodilatory effects. When the PDE5 inhibitor is introduced, the c GMP is broken down. So, less c GMP means more blood flow et voilà, an erection. For example, Viagra is made with sildenafil and has a wait time of 30-60 minutes lasting for up to 4 hours.

Content Header .feed_item_answer_user.js-wf-loaded . If you’re looking for a less costly Viagra, you might want to ask your doctor about sildenafil. It's the active ingredient in both branded Viagra and the drug Revatio, which is a lower dose than Viagra and approved to treat pulmonary arterial hypertension. The important difference: Generic Revatio is available for a fraction of the cost. "Generic Revatio is considerably less expensive, and it is the same drug as Viagra with the same safety and effectiveness," says Bradley Anawalt, M. D., an endocrinologist and professor of medicine at the University of Washington in Seattle who chairs the Endocrine Society's Hormone Health Network. At a lower dose, sildenafil is approved to treat pulmonary arterial hypertension—the higher dose is reserved for treating erectile dysfunction (ED). Anawalt explains that there's a chance your insurance might not cover it to treat ED.
