Cost-effectiveness of a fixed-dose combination of solifenacin and oral controlled adsorption system formulation of tamsulosin in men with lower urinary tract symptoms associated with benign prostatic hyperplasia

摘要

BackgroundStorage symptoms, associated with benign prostatic hyperplasia (BPH), often co-exist with voiding symptoms in men with lower urinary tract symptoms (LUTS). Storage symptoms are likely to be most bothersome, and may not be adequately resolved by treatment with α-blocker or antimuscarinic monotherapy. A recent randomised controlled phase 3 trial (NEPTUNE) demonstrated that a fixed-dose combination (FDC) of solifenacin 6 mg plus an oral controlled absorption system (OCAS™) formulation of tamsulosin (TOCAS, 0.4 mg) improved storage symptoms, as well as quality of life, compared with TOCAS alone in men with moderate-to-severe storage symptoms and voiding symptoms. This analysis aimed to assess the cost-effectiveness of a FDC tablet of solifenacin 6 mg plus TOCAS relative to tolterodine plus tamsulosin given concomitantly, from the perspective of the UK National Health Service (NHS).
