Viagra, with the active ingredient sildenafil citrate, is a prescription medication used to treat erectile dysfunction (ED). It helps men achieve and maintain an erection sufficient for sexual intercourse by increasing blood flow to the penis when sexually stimulated. Viagra is widely known as one of the first and most popular treatments for erectile dysfunction and is available in 25mg, 50mg, and 100mg doses. It is usually taken as needed, about one hour before sexual activity. Viagra is a safe and effective treatment for most men with ED and is known for its reliability and quick onset of action.
Viagra works by inhibiting an enzyme called phosphodiesterase type 5 (PDE5), which regulates blood flow in the penis. When sexually stimulated, this enzyme can limit the amount of blood that flows to the penis, making it difficult to achieve an erection. By blocking PDE5, sildenafil allows the blood vessels in the penis to remain dilated, increasing blood flow and making it easier to achieve and maintain an erection. The medication typically starts working within 30 to 60 minutes and its effects last for up to 4-5 hours, giving a sufficient time window for sexual activity.
