Sildenafil is a well-known medication primarily used to treat erectile dysfunction (ED) and, in some cases, pulmonary arterial hypertension (PAH). It belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors, which work by increasing blood flow to specific areas of the body.
How Does Sildenafil Work?
Sildenafil helps relax blood vessels, allowing improved circulation.
-
For erectile dysfunction, it enhances blood flow to the penis during sexual stimulation, helping to achieve and maintain an erection.
-
For pulmonary hypertension, it reduces the pressure in the lungs’ blood vessels, making it easier for the heart to pump blood.
