Viagra (generic name: Sildenafil) is a widely known prescription medication used to treat erectile dysfunction (ED) in adult men. Erectile dysfunction is a common condition that can result from physical, psychological, or lifestyle factors, and Viagra is designed to help improve blood flow to the penis, assisting men in achieving and maintaining an erection suitable for sexual activity when used under proper medical guidance.

Viagra is part of a class of medications called phosphodiesterase type 5 (PDE5) inhibitors, which work by relaxing blood vessels in the penis and enhancing the natural response to sexual stimulation. It does not increase sexual desire, but helps the body respond effectively during sexual activity.

How Viagra Works

Viagra works by increasing blood flow to the penis during sexual arousal, enabling men with ED to achieve and maintain an erection. The medication is usually taken 30–60 minutes before sexual activity, and its effects can last up to 4–5 hours, depending on individual response and dosage.

Viagra is available in multiple doses, allowing a healthcare provider to determine the safest and most effective amount for each patient.
