Combination therapy with curcumin plus tamsulosin and finasteride in the treatment of men with benign prostatic hyperplasia: a single center, randomized control study.

Abstract

BackgroundTo perform a prospective, randomized, single center study to investigate the efficacy of combined use of curcumin, an anti-inflammatory agent, with the best standard management (BSM, tamsulosin and finasteride) in benign prostatic hyperplasia (BPH) patients.MethodsOne hundred and twenty-two consecutive patients were randomized to receive tamsulosin 0.2 mg, finasteride 5 mg, and curcumin 2,250 mg once a day (curcumin + BSM group, n=61) versus tamsulosin 0.2 mg, finasteride 5 mg, and placebo (BSM group, n=61) for 6 months. The safety of treatments and their efficacy on improving waist circumference (WC), periprostatic fat thickness (PPFT), lower urinary tract symptoms (LUTS), and sexual function were assessed at baseline and month 6.ResultsOne hundred and sixteen patients completed the whole procedure (116/122, 95.1%). There were significant improvements in prostate volume (PV), maximum flow rate (Qmax), the International Prostate Symptom Score (IPSS), IPSS-voiding subscore (IPSS-V), IPSS-storage subscore (IPSS-S), and quality of life (QoL) from baseline after treatment in both groups. Additionally, both WC and PPFT decreased significantly after treatments than those at baseline in the curcumin + BSM group. Also, WC and PPFT in the curcumin + BSM group were significantly lower than those in the BSM group. In addition, IPSS-S, QoL score, and the 5-item version of the International Index of Erectile Function (IIEF-5) in the curcumin + BSM group improved significantly compared with those in the BSM group.ConclusionsWe conclude that curcumin combined with tamsulosin and finasteride has more beneficial effects in reducing PPFT, protecting erectile function, improving urinary retention symptoms, and QoL scores in BPH patients compared to tamsulosin and finasteride alone.Trial RegistrationChinese Clinical Trial Registry ChiCTR2100043800.
