Introduction to Viagra

Viagra, known by its generic name Sildenafil, is a medication primarily used to treat erectile dysfunction (ED) in men. It helps men achieve and maintain an erection by increasing blood flow to the penis during sexual arousal. Additionally, it is used to treat pulmonary arterial hypertension (PAH), a condition characterized by high blood pressure in the arteries of the lungs.

Composition of Viagra

Viagra contains the active ingredient Sildenafil Citrate. This compound works by inhibiting an enzyme called phosphodiesterase type 5 (PDE5), which results in increased levels of cyclic guanosine monophosphate (cGMP) in the body, leading to muscle relaxation and improved blood flow.

Precautions of Viagra
