It is a phosphodiesterase type 5 inhibitor which is used for the treatment of erectile dysfunction. It has a role as an EC 3.1.4.35 (3',5'-cyclic-GMP phosphodiesterase) inhibitor and a vasodilator agent. It is a sulfonamide, a pyrrolopyrimidine, a N-alkylpiperazine, a primary alcohol and an aromatic ether."}]
