What is Viagra?

Viagra, known by its generic name sildenafil citrate, is a prescription medication used to treat erectile dysfunction (ED) in men. By enhancing blood flow to the penis, Viagra helps achieve and maintain an erection during sexual stimulation. It belongs to a class of drugs known as phosphodiesterase type 5 (PDE5) inhibitors.

How Viagra Works

Viagra works by inhibiting PDE5, an enzyme that breaks down cyclic guanosine monophosphate (cGMP), a molecule responsible for relaxing blood vessels. By blocking PDE5, sildenafil citrate allows cGMP levels to remain elevated, promoting increased blood flow to the penis and enabling an erection in response to sexual stimulation.

Benefits of Viagra

• Proven Efficacy: Clinical trials show that Viagra significantly improves the ability to achieve and maintain an erection.
• Rapid Onset: Typically works within 30-60 minutes of ingestion.
• Flexible Dosing: Available in 25 mg, 50 mg, and 100 mg doses to suit individual needs.
• Extended Effect: Effects can last up to 4-6 hours in most individuals.

Dosage and Administration

Viagra is available in three strengths: 25 mg, 50 mg, and 100 mg. The recommended starting dose is 50 mg, taken as needed approximately 30-60 minutes before sexual activity. The dose may be adjusted to 25 mg or 100 mg depending on efficacy and tolerability.

Viagra should not be taken more than once per day. For best results, avoid taking it with a high-fat meal, which may delay its onset of action.
