Abstract

OBJECTIVES: To further discuss the method of evaluating curative effect on erectile dysfunction(ED).

METHODS: Clinical trials(Phase II) of sildenafil and phentolamine were both 8-week-long, randomized, double-blind and placebo-controlled. Not only the curative effect between each treatment group and placebo group but also between the treatment groups were compared. The dosage of sildenafil and phentolamine was respectively 50-100 mg and 40 mg.

RESULTS: Efficiency, success rate of sexual intercourse and general curative effect in sildenafil and phentolamine groups were respectively 79.17%, 75.00%, 83.33% and 52.38%, 85.71%, 52.38%. The result revealed a statistically significant (P 0.05).

CONCLUSIONS: Most assessments of curative effect of ED drugs come from questionnaires answered subjectively by patients. The Lack of objective assessment criteria way lead to the non-conformity between trial results and clinical practices. So the curative effect of drugs shall be assessed more accurately and from more perspectives.
