Pharmaceutical Information
Drug Name Tadalafil
Drug ID BADD_D02106
Description 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.[L39100, L39105] 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.[A242287]
Indications and Usage 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).[L39095,L39439] It is also indicated for the treatment of pulmonary arterial hypertension (PAH) both alone and in combination with [macitentan] or other endothelin-1 antagonists.[L39100,L39105]
