Viagra, or sildenafil, treats erectile dysfunction (ED) by increasing blood flow to the penis. This allows for a firmer erection sufficient for sexual intercourse. It’s a prescription medication, so you’ll need a doctor’s consultation before using it.
How Viagra Works
Viagra works by inhibiting an enzyme called phosphodiesterase-5 (PDE5). PDE5 breakdown of cGMP, a molecule that relaxes blood vessels, is blocked by Viagra. This results in increased blood flow, leading to improved erectile function.
Viagra’s Uses Beyond ED
While primarily known for ED, sildenafil also finds use in treating pulmonary arterial hypertension (PAH), a condition characterized by high blood pressure in the arteries leading to the lungs. This application targets a different physiological mechanism, but uses the same drug’s property of relaxing blood vessels.
Always consult your physician to determine the correct dosage and assess any potential drug interactions before taking Viagra, regardless of the intended use. Proper medical guidance ensures safe and effective use.
