Vardenafil hydrochloride trihydrate is a selective and orally active inhibitor of phosphodiesterase-5 (PDE5) with an IC50 of 0.7 nM. It shows inhibitory effects towards PDE1 and PDE6 with IC50s of 180 nM and 11 nM, respectively, while IC50s are >1000 nM for PDE3 and PDE4. It competitively inhibits cyclic guanosine monophosphate (cGMP) hydrolysis, which increases cGMP levels. It can be used for research related to erectile dysfunction, hepatitis, and diabetes.
