Overview

Tadalafil is a medication commonly known by the brand name Cialis. It is primarily used to treat erectile dysfunction (ED), benign prostatic hyperplasia (BPH), and pulmonary arterial hypertension (PAH). Tadalafil belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors. Tadalafil is a PDE5 inhibitor that works by increasing blood flow to the penis, facilitating improved erectile function in individuals with ED. It also relaxes the muscles in the prostate and bladder, helping to alleviate urinary symptoms associated with BPH. In the case of PAH, it relaxes the blood vessels in the lungs, reducing the pressure in the pulmonary arteries.
