Sildenafil Citrate

Description

Sildenafil Citrate is a phosphodiesterase type 5 (PDE5) inhibitor primarily used for the treatment of erectile dysfunction (ED) in men and pulmonary arterial hypertension (PAH). It works by increasing blood flow to the penis during sexual arousal, which helps men achieve and maintain an erection. Sildenafil also relaxes the blood vessels in the lungs, allowing for better blood flow and reducing symptoms of PAH.

Sildenafil is commonly marketed under the brand name Viagra, though it is available as a generic formulation.
