简要总结
An active post-marketing surveillance study is proposed in this study to evaluate the safety and efficacy of this FDC in BPH patients. Silodosin is a highly selective α1A-adrenoceptor antagonist indicated for the treatment of the signs and symptoms of benign prostatic hyperplasia (BPH). Oral silodosin has a rapid onset of effect in men with lower urinary tract symptoms (LUTS) associated with BPH, with improvements seen in voiding and storage symptoms, maximum urinary flow rate and health-related quality of life in well-designed, 12-week trials. Silodosin is generally well tolerated and is a useful option for the treatment of LUTS associated with BPH. The silodosin dose recommended by the FDA is 8 mg orally once a day. Dutasteride is an oral synthetic 4-azasteroid, is a potent, selective, irreversible inhibitor of type 1 and type 2 5alpha-reductase (5AR), the enzyme that converts testosterone to dihydrotestosterone (DHT) intracellularly. Oral dutasteride 0.5 mg once daily is approved for the treatment of moderate to severe symptomatic BPH in men with an enlarged prostate to improve symptoms, and to reduce the risk of acute urinary retention (AUR) and the need for BPH-related surgery. The good efficacy and tolerability of dutasteride maintained for up to 4 years in open-label extension studies is well- reported.
