Viagra

Overview

Viagra, known scientifically as sildenafil, is primarily used for treating erectile dysfunction and pulmonary arterial hypertension. It falls under the category of PDE5 inhibitors, enhancing blood flow to specific body areas. Available as an oral tablet, Viagra is taken about 30 minutes to 1 hour before sexual activity.
