Detailed Guide to Sildenafil: Uses and Important Information

Sildenafil, commonly known by its brand name Viagra, is a medication that inhibits PDE5 enzymes. It is mainly used to treat erectile dysfunction and manage pulmonary hypertension by relaxing the blood vessels in the lungs. This relaxes lung vessels, lowers pulmonary pressure, and improves stamina. Available typically in 25mg to 100mg doses, sildenafil enhances blood flow, leading to firmer and longer-lasting erections.

How sildenafil works
Sildenafil blocks PDE5 enzymes, preventing the breakdown of cGMP in erectile tissues. Nitric oxide stimulates guanylate cyclase, increasing cGMP levels, which relaxes smooth muscles and boosts blood flow to the penis. By inhibiting PDE5, sildenafil sustains higher cGMP levels, resulting in more effective and longer-lasting erections.

This process also helps reduce pressure in the pulmonary arteries. Like all medications, sildenafil might cause side effects, though not everyone experiences them. Common adverse effects include headaches, nasal congestion, indigestion, nausea, flushing, visual changes, or dizziness. Serious issues like prolonged erections beyond 4 hours, sudden vision loss, or chest pain require immediate medical attention. Mixing sildenafil with illegal substances can cause priapism—an emergency condition needing urgent care.
