Viagra, or sildenafil citrate, primarily treats erectile dysfunction (ED). It works by increasing blood flow to the penis, facilitating an erection when sexually stimulated. This improved blood flow is achieved through the inhibition of a specific enzyme, PDE5.
How Viagra Works
Sexual stimulation triggers the release of nitric oxide, a chemical messenger relaxing blood vessels. PDE5 normally counteracts this, limiting blood flow. Viagra blocks PDE5, allowing the nitric oxide to work more effectively.
Beyond Erectile Dysfunction
While primarily known for ED treatment, Viagra also shows promise in treating pulmonary arterial hypertension (PAH), a condition characterized by high blood pressure in the arteries supplying the lungs. It improves blood flow in these vessels, easing the symptoms of PAH. Always consult a doctor before using Viagra for any condition. Dosage and monitoring are crucial. Proper diagnosis and individual medical history significantly influence treatment plans.
