[Aildenafil citrate: a new potent and highly selective phosphodiesterase type 5 inhibitor for the treatment of erectile dysfunction].

OBJECTIVE

To evaluate the efficacy and safety of aildenafil citrate, an oral phosphodiesterase type 5 inhibitor, in the treatment of erectile dysfunction.

METHODS

Integrated analyses were made of 8-week, randomized, double-blind, placebo-controlled phase 2 clinical trials involving 250 men with mild-to-severe erectile dysfunction of various etiologies who received aildenafil citrate 30 or 60 mg (n = 167) or placebo (n = 83).

RESULTS

The statistic results of International Index of Erectile Function, Patient Sexual Encounter Profile (SEP) diaries and Global Assessment Question (GAQ) were significantly higher in the aildenafil citrate patients than in the placebo controls. The main drug-related adverse events were flushing, headache, dizziness and naupathia, which were mild and could be self-relieved.

CONCLUSION

The aildenafil citrate therapy significantly ameliorated erectile function and was well tolerated by a wide range of patients with erectile dysfunction.
