Avanafil(TA-1790) is a potent and highly selective phosphodiesterase-5(PDE-5) inhibitor(IC50=5.2 nM) for erectile dysfunction; lower selectivity against PDE1, PDE6, and PDE11.IC50 value: 5.2 nM [1]Target: PDE5Avanafil is highly selective toward PDE5 and against all other PDE isozymes tested. Lower selectivity against PDE1, PDE6, and PDE11 is consistent with results from randomized, placebo-controlled, phase 3 trials in which musculoskeletal and hemodynamic adverse events were reported in <2% of patients and no color vision-related abnormalities were reported with avanafil doses up to 200mg once daily [2]. Intraduodenal doses of avanafil or sildenafil (0.1 and 1 mg/kg) potentiated the AUC of nitroglycerin induced hypotension. However, the potentiating effect of avanafil at 1 mg/kg was significantly weaker than that of sildenafil (p <0.05) [3].
