Treatment of acute phase of Peyronie’s disease with tamoxifen and vardenafil/tadalafil off label

Peyronie’s Disease (PD) causes penile curvature and pain in acute phase. In two preclinical studies, tamoxifen and vardenafil (T&T) together showed to be effective in the acute phase. The aim of this study was to describe the clinical results of the off-label treatment of PD patients with T&T in combination with vacuum erection device (VED) in St Antonius hospital, urology outpatient clinic. Baseline descriptive Statistics, Fisher Exact and Chi-Square Test were used. 48 Men were included, mean age 53.0 years (SD 9.5), baseline curvature 46.7 ° (SD 18.8), median duration four months, 70.8% ( n = 48) painful erections. Dorsal curvature is found in 27 (56.3%) men, mean stretched penile length 13.4 cm. Mean use of T&T was 13 weeks (1–52 weeks). Curvature improvement in 27.7% men, pain reduction in 48.5% men, sexual intercourse/coitus improvement in 34.2% men, erection improvement in 14.6% men. Adverse reactions of T&T in 39.6% ( n = 19). This was the first study investigating the use of T&T in acute phase PD patients. 27.7% of patients reported improvement in curvature with T&T.
