Sildenafil 75mg capsule

Sildenafil is categorized as a Selective Phosphodiesterase (PDE) type 5 inhibitor. It is a vasoactive agent that is commonly prescribed to treat erectile dysfunction (impotence) in men, as well as reduce symptoms in patients with pulmonary arterial hypertension (PAH). Sildenafil increases blood flow to particular areas of the body, including the penis, by decreasing vascular resistance and causing relaxation of the muscles.
