Orally active, cGMP-competitive, potent and selective phosphodiesterase type 5 (PDE5) inhibitor with ED and hypertension therapeutic efficacy in vivo.
Udenafil (DA-8159) is an orally active, cGMP-competitive, potent and selective phosphodiesterase type 5 (PDE5) inhibitor (cellular PDE5 activity IC50 = 5.84/8.25 nM in rabbit/human platelets; IC50 = 53.3 nM/PDE6, 870 nM/PDE1, 52 μM/PDE3,101 μM/PDE2). Udenafil shows in vivo therapeutic efficacy in a rat model of monocrotaline-induced pulmonary hypertension (1 or 5 mg/kg bid po.) and induces penile erection in experimental animals in vivo (0.3-10 mg/kg po. in rabbits & rats).

In this study, we evaluated the effects of oral administration of DA-8159, a selective phosphodiesterase-5 inhibitor, on the development of pulmonary hypertension (PH) induced by monocrotaline (MCT). Rats were administered either MCT (60 mg/kg) or saline. MCT-treated rats were divided
