Daily low-dose tadalafil may reduce the penile curvature progression rate in patients with acute Peyronie's disease: a retrospective comparative analysis
Abstract
The aim of this study was to evaluate the clinical outcomes of patients in acute phase of Peyronie’s disease (PD) treated with daily low-dose of Tadalafil. An observational retrospective study involving patients in acute phase of PD with erectile dysfunction (ED) was designed. All subjects were offered Tadalafil 5 mg one tablet a day. Men who accepted treatment were compared to patients who refused Tadalafil. Penile curvature progression was chosen as the primary outcome. PD Questionnaire (PDQ) and IIEF-5 scores were selected as secondary outcomes. A total of 191 patients were included in the study (108 intervention vs. 83 control). Penile curvature progression rate was significantly lower in subjects taking Tadalafil at 12 weeks (25.9% vs. 39.7%, p = 0.042). Mean IIEF-5 score improved in the intervention group, becoming significantly higher compared to the observation group at 12 weeks (19.3 vs. 11.2 points, p < 0.001). Mean PDQ-Overall and PDQ-Penile Pain scores only improved in the intervention group and the statistically significant differences at baseline between groups became not statistically significant at 12 weeks (p = 0.001 vs. p = 0.232 and p < 0.001 vs. p = 0.078, respectively). Daily low-dose Tadalafil in patients with acute phase of PD seems to significantly reduce the penile curvature progression rate compared to observation, especially when it is administrated early. It also appears to improve erectile function and PD-related symptoms.
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 191 participants or records.
