Intraplaque verapamil injection for treatment of Peyronie's disease.J La State Med Soc. 1998 Sep; 150(9):431-4.JL
We report our findings on the effects of intraplaque injection of verapamil for the treatment of Peyronie's disease. We followed 11 men with Peyronie's disease in a nonrandomized constant dose study. During our study, four men received testosterone supplementation; five received vitamin E and/or potassium aminobenzoate (potaba) concurrent with verapamil; two received injections of verapamil only. Plaque size decreased significantly in 7 of 11 patients (55%); softening occurred in 6 (55%); 4 of 8 patients (50%) had decreased curvature. Deformities and symptoms did not recur in any patients who reported improvement. Three of 11 (27%) patients failed treatment and elected to undergo surgical correction. All four (100%) of our study participants with pain had complete resolution after intraplaque verapamil injection compared with Levine et al's 91%. We have demonstrated that intraplaque verapamil injection is a promising treatment for Peyronie's disease in that it may circumvent surgical intervention and may be used with concurrent therapies.
