摘要: DA-8159, a new phosphodiesterase 5 inhibitor, was assessed for its erectogenic potential by penile erection test in rats, the relaxation of isolated rabbit corpus cavernosum (CC), and estimation intracavernous pressure (ICP) anesthetized dog. Oral administration DA-8159 (0.3 to 1 mg/kg) increased number erections rats with increasing dosage, highest index at 10 mg/kg. induced phenylephrine (PHE)-induced contractions CC decreased IC50 nitric oxide donor sodium nitroprusside (SNP) dose-dependent fashion. In pentobarbital-anesthetized dogs, intravenous (1 approximately 300 g/kg) potentiated increase ICP intracavernosal SNP dose-related manner. These findings suggest that has significant therapeutic treatment erectile dysfunction.
