Structured self-rated response to iontophoresis with verapamil and dexamethasone in peyronie's disease

Abstract

Introduction. New therapies evolve for the treatment of Peyronie's disease (PD) including the application of dexamethasone and verapamil using Electro Motive Drug Administration (EMDA). Patients and Methods. Patients with PD were routinely offered Potaba, Vitamin E, tamoxifen or colchicine for 6 to 18 months and for those with no improvement, 18 applications of dexamethasone and verapamil using EMDA occurred over a 6 week period. All 30 patients receiving EMDA therapy completed a questionnaire before and after treatment. The data was collected from December 2004 to November 2009 and analysed to evaluate the effectiveness of the treatment. Results. Median age of patients was 59 (range 39-71). Curvature was the most common presenting complaint (73.3%) followed by pain (23.3%), erectile dysfunction (13.3%), and lump (13.3%). 24/30 (80%) reported an improvement in symptoms after EMDA. 16 of the responders (66.7%) had a stable plaque for at least 6 months. The patients who complained of shortening of the penis (P = 0.003) or lowered sexual desire (P = 0.024) expressed subsequently significant response to treatment. There was statistically significant (P = 0.019) improvement of penile deviation reported by responding men. Conclusion. A significant proportion of patients who received EMDA reported decreased curvature following iontophoresis. No serious adverse reactions developed. © 2014 Abas Kokab et al.
