Pentoxifylline (PTX) with other antioxidants, in patients with PD enrolled for a conservative medical management.

Methods: We carried out a controlled study on 240 patients diagnosed with Peyronie's Disease (PD). We have divided two treatment groups, which differ from each other only for the association with PTX-penile injection. Two groups (A and B) were totally composed by 160 PD patients (80 patients for each group): Group A=PTX injection (penile and peri-lesional) 100 mg, every two weeks for six months + PTX 400 mg /oral/ twice daily + propolis 600 mg / oral / daily + blueberries 160 mg /oral/ daily + Vitamin E 600 mg / oral / daily + topical Diclofenac sodium 4% gel / twice a day, for a period of 6 months. Group B=the same therapy of group A but without PTX penile injection. Patients who refused treatment, for various reasons, were included in the control group=Group C (80 patients).

Results: In groups A and B after 6 months of treatment a reduction of penile plaque volume of 50.3% and 25.9% respectively was observed, while in group C a mean increase in plaque volume of 131% was observed. Furthermore, in groups A and B, the mean curvature decrease was -11.07° and -4.4° respectively, while in group C a mean increase of curvature =+14.09° was observed. Conclusion: Our results showed that multimodal treatment with PTX associated with antioxidants and topical Diclofenac is significantly effective in treating PD. Treatment outcomes obtained in the treatment-group A are statistically more significant than those achieved in group B. Pentoxifylline is more effective when the treatment program includes both routes of administration: oral + perilesional injection.
