A Prospective, Observational Study of Use Combination Silodosin 8 mg Plus Serenoa Repens, Urtica Dioica, Cucurbita Pepo (Rotaprost) Compared With Silodosin 8 mg Alone in Treatment Patients with Benign Prostate Hyperplasia

Abstract

Benign prostatic hyperplasia (BPH) is one of the most common causes of lower urinary tract symptoms (LUTS) in older men. Nowadays, there are several plant extracts used for the treatment of LUTS due to BPH. The aim of this study is to compare the effect of combining silodosin 8 mg with Serenoa repens, Urtica dioica, Cucurbita pepo (Rotaprost 530 mg) compared to silodosin 8 mg and Rotaprost 530 mg alone in patients with LUTS/BPH. Four hundred five men with symptomatic BPH were recruited for the study from June 2020 to January 2021. Three hundred eighty-nine patients were followed up for 6 months. All participants provided written informed consent. This prospective study included analysis of three treatment groups: Group I patients ( n = 130) received a combination of silodosin 8 mg and Rotaprost 530 mg (containing a dry extract of Serenoa repens 80 mg, a dry extract of Urtica dioica 150 mg, a dry extract of Cucurbita pepo seeds 200 mg, zinc (in the form of zinc picolinate) 0.105 mg, and selenium (as sodium selenite) 22.5 µg); the group II ( n = 129) received silodosin 8 mg alone, and the group III ( n = 130) received Rotaprost 530 mg alone. Outcomes were measured by changes from baseline in International Prostate Symptom Score (IPPS) total score, PSA value, prostate volume, residual urine after urination, and maximum flow rate. Statistical significance was set at P < 0.05. In group I, IPSS, prostate volume, and maximum urinary flow rate (Qmax) improved significantly ( P < 0.05) compared with groups II and III during follow-up. Prostate volume in group I showed a significant decrease only during 6 months of therapy ( P < 0.05). No serious adverse effects were registered in the three groups. Combination therapy with silodosin 8 mg significantly reduced LUTS/BPH, Qmax, and prostate volume compared with silodosin 8 mg alone. Rotaprost 530 mg can also reduce PSA by at least 20.6−25.7% after 6-months of treatment.
