Viagra, containing sildenafil citrate, primarily treats erectile dysfunction (ED), helping men achieve and maintain an erection firm enough for satisfactory sexual intercourse. It works by increasing blood flow to the penis.
This increased blood flow is facilitated by Viagra’s inhibition of a specific enzyme, PDE5. PDE5 normally breaks down a substance called cGMP, which plays a key role in penile erection. By blocking PDE5, Viagra allows cGMP levels to rise, promoting vasodilation and facilitating the erection process.
While primarily used for ED, Viagra has shown promise in treating pulmonary arterial hypertension (PAH), a condition characterized by high blood pressure in the arteries leading to the lungs. This is due to sildenafil’s ability to relax blood vessels, lowering blood pressure.
Remember, Viagra is a prescription medication. Consult your doctor before use to discuss your medical history and potential side effects. They can help determine if Viagra is suitable for you and advise on the appropriate dosage.
Common side effects include headache, facial flushing, nasal congestion, and visual disturbances. More serious side effects are rare but require immediate medical attention. Always follow your doctor’s instructions.
