2 . Description:


Viagra is the trade name for a drug called Sildenafil. Viagra is one of a class of drugs known as PDE-5 (Phosphodiesterase type 5) inhibitors.Viagra and the other PDE-5 inhibitors can help men with erectile dysfunction (male impotence) by enhancing the erectile response when a man is sexually stimulated. Aside from Viagra, the other drugs in this class are Cialis (Tadalafil) and Levitra (Vardenafil).


Viagra does not cause a man to be sexually aroused. Viagra is only effective if you are sexually aroused. To understand how it works you need to understand the mechanics of how a man gets an erection. When you get sexually stimulated, the nervous system in the erectile tissue of your penis releases nitric oxide (NO).


The nitric oxide stimulates an enzyme that produces something called a messenger cyclic guanosine monophosphate (cGMP). The GMP relaxes the smooth muscle cells. One result of this is that the arteries in your penis dilate and the blood can flow into your penis more easily. Another result is that the erectile tissue itself fills with blood. Both of these process result in an erection. Viagra works by maintaining the level of cGMP in the smooth muscle cells.If you are not turned on, your brain will not stimulate the release of any nitric oxide and you will not produce any cGMP.


3 . Function:


Sildenafil citrate, sold as Viagra, Revatio and under various other trade names, is a drug used to treat erectile dysfunction and pulmonary arterial hypertension (PAH). It was originally discovered by Pfizer scientists Andrew Bell, David Brown, and Nicholas Terrett.The primary indication of sildenafil is treatment of erectile dysfunction (inability to sustain a satisfactory erection to complete intercourse). Its use is now standard treatment for erectile dysfunction in all settings, including diabetes.

In clinical trials, the most common adverse effects of sildenafil use included headache, flushing, dyspepsia, nasal congestion and impaired vision, including photophobia and blurred vision.Some sildenafil users have complained of seeing everything tinted blue (cyanopsia).Some complained of blurriness and loss of peripheral vision. In July 2005, the FDA found that sildenafil could lead to vision impairment in rare cases and a number of studies have linked sildenafil use with nonarteritic anterior ischemic optic neuropathy.

Rare but serious adverse effects found through postmarketing surveillance include priapism, severe hypotension, myocardial infarction (heart attack), ventricular arrhythmias, stroke, increased intraocular pressure, and sudden hearing loss. As a result of these postmarketing reports, in October 2007, the FDA announced that the labeling for all PDE5 inhibitors, including sildenafil, required a more prominent warning of the potential risk of sudden hearing loss.
