Description

What is tadalafil used for?
Tadalafil is a medicine that is commonly used for the following conditions.

Erectile dysfunction, a condition where you have trouble getting or keeping an erection
Pulmonary arterial hypertension, a condition where you have high blood pressure in the blood vessels that carry blood from your heart to your lungs
Benign prostatic hyperplasia (BPH), a condition where the prostate gland has become enlarged
Tadalafil may also be used for other conditions as determined by your healthcare provider.

How does tadalafil work (mechanism of action)?
Tadalafil works by blocking the activity of an enzyme called phosphodiesterase 5 (PDE5). This enzyme usually stops some types of muscles from relaxing, including the muscles lining some types of blood vessels. By blocking PDE5, the muscles will relax and blood flow increases. For erectile dysfunction, it increases blood flow to the penis when aroused. This makes it easier to get and keep an erection. For pulmonary arterial hypertension, tadalafil relaxes the blood vessels in the lungs. This lowers blood pressure and reduces strain on the heart. For benign prostatic hyperplasia, tadalafil relaxes the muscles of the bladder and prostate, making it easier to urinate and reducing symptoms.
