Potassium para-aminobenzoate for the treatment of Peyronie's disease: is it effective?Tech Urol. 1997 Fall; 3(3):135-9.TU
The medical treatment of Peyronie's disease remains controversial. Oral and injectable medications have been used with little documented disease specific effectiveness. Potassium para-aminobenzoate (POTABA) has long been suggested as a treatment for the plaque, curvature, and pain produced by chronic Peyronie's disease. We report a retrospective review of 32 patients treated for at least 3 months with 12 g of POTABA powder daily and followed for 8 to 24 months. Symptom resolution demonstrated improvement in penile discomfort in 8 of 18 patients, decreased plaque size in 18 of 32 patients, and improvement in penile angulation in 18 of 31 patients. Complete resolution of angulation was reported in 8 of 31 patients. While this review was retrospective and uncontrolled, it does suggest a place for POTABA in the treatment of Peyronie's disease. In order to confirm these findings and to control for the natural history of spontaneous resolution of Peyronie's disease symptomatology, a prospective, double-blind, multicenter, well-controlled study with objective criteria should be established.
