Viagra: A Comprehensive Guide

Viagra, known scientifically as sildenafil citrate, is a medication widely used for the treatment of erectile dysfunction (ED). This condition affects millions of men worldwide and can impact self-esteem and relationships. Viagra works by enhancing blood flow to the penis, helping men achieve and maintain an erection sufficient for sexual activity.

What is Viagra?

Viagra is a phosphodiesterase type 5 (PDE5) inhibitor. It was first introduced by Pfizer and approved by the FDA in 1998. The primary function of this medication is to treat erectile dysfunction by increasing blood flow to the penile area when a man is sexually stimulated.

How Does Viagra Work?

When a man is sexually aroused, nitric oxide is released into the penis, leading to the production of cyclic guanosine monophosphate (cGMP). This chemical relaxes the smooth muscles and dilates the blood vessels in the penis, allowing increased blood flow and leading to an erection. Viagra works by inhibiting the breakdown of cGMP by PDE5, thereby sustaining the erection process.

Indications for Use

Viagra is prescribed for the treatment of erectile dysfunction. It may also be used to treat pulmonary arterial hypertension under the brand name Revatio. However, its primary use remains the facilitation of erections in men with ED.

How to Use Viagra

– Dosage: The standard starting dose for Viagra is 50 mg, taken as needed about one hour before sexual activity. Depending on efficacy and tolerability, the dose may be increased to 100 mg or decreased to 25 mg. It should not be taken more than once a day.
– Administration: Viagra should be taken orally with water. It can be taken with or without food, but a high-fat meal may delay its onset of action.
