Antiinflamm Antiallergy Agents Med Chem. 2019;18(2):151-161. doi: 10.2174/1871523018666181128164252.


Objective: Chronic Prostatitis/Chronic Pelvic Pain Syndrome (CP/CPPS) is reported in the literature ranging from 1 to 14.2%. The aim of the present study was to assess the impact on patient's quality of life and symptoms of Flower pollen extract in association with vitamins (Deprox 500®) in comparison with Serenoa repens 320 mg (Permixon 320 mg® by Pierre Fabre) in patients with CP/CPPS.

Methodology: All consecutive patients, with a diagnosis of CP/CPPS, referred to our center from January to August 2016, were screened to be enrolled in this single-center, randomized, controlled trial. The main outcome measure was the evaluation of IPSS/NIHCPSI (International Prostatic Symptom Score/NIH-Chronic Prostatitis Symptom Index) score variation and the assessment of the quality of life and symptoms at the end of the therapy. The second outcome measure was the evaluation of the comorbidity role in the CP/CPPS therapy. 63 patients were analyzed; patients were randomized into two groups: 29 patients were treated with Deprox 500® 2 tablets/day for 6 weeks and 34 patients with Serenoa repens 320 mg, 1 tablet/day for 6 weeks.

Results: The mean score variation for IPSS was -12.7 ± 4.3 in the Deprox 500® group and -7.8 ± 4.7 in the Serenoa repens group (p=0.0005) while for NIH-CPSI was -17.3±3.1 in the Deprox 500® group and -13.6±4.8 in the Serenoa repens group (p=0.0016). By accounting only the symptoms part of NIH-CPSI questionnaire, the mean score variation reported was -11.5±2.5 in the Deprox 500® group and -9.02±4.0 in the Serenoa repens group (p=0.009321). Furthermore, analyzing the comorbidity subgroups, in patients with hypertension, the mean IPSS score variation was -14.3±3.2 in the Deprox 500® group and - 9.02±4.0 in the Serenoa repens group.

Conclusion: In conclusion, in patients with CP/CPPS, Deprox 500® improves IPSS and NIH-CPSI scores up to 74.5% and 84.5% respectively. Furthermore, in patients with hypertension, the antioxidant effect of Deprox 500® reduces the mean IPSS score of 82.7%.
