Background

Tadalafil is a selective phosphodiesterase-5 inhibitor that is used in the treatment of erectile dysfunction (ED), pulmonary arterial hypertension (PAH), and benign prostatic hypertrophy. It was first approved in 2003 by the FDA for use in ED and later in 2009 for PAH. In contrast to other PDE5 inhibitors like sildenafil, tadalafil has greater selectivity for PDE5 and a longer half-life which has made it a more suitable option for chronic once-daily dosing in the treatment of PAH.

Indication

Tadalafil is indicated for the treatment of erectile dysfunction (ED) and either alone or in combination with finasteride for the treatment of benign prostatic hypertrophy (BPH). It is also indicated for the treatment of pulmonary arterial hypertension (PAH) both alone and in combination with macitentan or other endothelin-1 antagonists.

Associated Conditions
Benign Prostatic Hyperplasia (BPH), Erectile Dysfunction, Pulmonary Arterial Hypertension (PAH)
