Intralesional verapamil for the treatment of Peyronie's disease: a review.

Multiple treatment options have been used for Peyronie's disease (PD) including intralesional injection of the calcium antagonist verapamil. The use of verapamil is based on its capacity to alter fibroblast function at several levels, including cell proliferation, extracellular matrix protein synthesis and secretion, as well as collagen degradation. Consequently, calcium antagonists may have the capacity to slow, prevent, or even reverse plaque formation and the progression of PD. The multicenter international experience with intralesional verapamil injection suggests that the majority of men with PD that receive treatment demonstrate durable reduction in pain, decrease in curvature, and improved sexual function. We review the scientific rationale, published literature, clinical experience, and technique of intralesional injection of verapamil.
