Tadalafil is a medication used to treat erectile dysfunction (ED), benign prostatic hyperplasia (BPH) and, in some cases, pulmonary arterial hypertension (PAH). Tadalafil is known commercially under the name Cialis® when used for ED and BPH, and Adcirca® when used for PAH. It belongs to a class of medications called phosphodiesterase type 5 (PDE5) inhibitors.
Tadalafil works by relaxing the blood vessels in the penis, allowing for greater blood flow during sexual arousal. It works by inhibiting the enzyme phosphodiesterase type 5 (PDE5), which breaks down cyclic guanosine monophosphate (cGMP). cGMP is a substance that is produced in response to sexual stimulation and that facilitates smooth muscle relaxation and vasodilation in the penis. By inhibiting PDE5, tadalafil allows cGMP to build up, facilitating an erection.
