BACKGROUND Combination therapy with dutasteride and tamsulosin provides significantly greater benefit than either monotherapy for various patient-reported outcomes in men with moderate-to-severe lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia (BPH) and prostatic enlargement. OBJECTIVE To investigate whether combination therapy is(More)
PURPOSE We investigated whether combination therapy with dutasteride and tamsulosin is more effective than either monotherapy alone for improving symptoms and long-term outcomes in men with moderate to severe lower urinary tract symptoms and prostatic enlargement (30 cc or greater). We report preplanned 2-year analyses. MATERIALS AND METHODS The CombAT(More)
Dihydrotestosterone (DHT) is the primary metabolite of testosterone in the prostate and skin. Testosterone is converted to DHT by 5alpha-reductase, which exists in two isoenzyme forms (types 1 and 2). DHT is associated with development of benign prostatic hyperplasia (BPH), and reduction in its level with 5alpha-reductase inhibitors improves the symptoms(More)
OBJECTIVES To assess the long-term safety and efficacy of dutasteride, a dual type 1 and type 2 5-alpha-reductase inhibitor, in the treatment of symptomatic benign prostatic hyperplasia and associated lower urinary tract symptoms. METHODS Data from two Phase IIIa multicenter, randomized, placebo-controlled trials of 2-year duration plus a 2-year(More)
OBJECTIVE To determine whether pretreatment with dutasteride, a dual 5alpha-reductase inhibitor (5ARI), reduces surgical blood loss or postoperative complications in patients with benign prostatic hyperplasia (BPH) who undergo transurethral resection of the prostate (TURP). PATIENTS AND METHODS This double-blind, randomized, placebo-controlled,(More)
OBJECTIVE • To investigate the influence of baseline variables on the 4-year incidence of acute urinary retention (AUR), benign prostatic hyperplasia (BPH)-related surgery and overall clinical progression in men treated with tamsulosin, dutasteride, or a combination of both. PATIENTS AND METHODS • The 4-year Combination of Avodart® and Tamsulosin (CombAT)(More)
OBJECTIVE • To assess the efficacy and safety of dutasteride compared with finasteride in treating men with symptomatic benign prostatic hyperplasia (BPH) for 12 months. PATIENTS AND METHODS • The Enlarged Prostate International Comparator Study was a multicentre, randomized, double-blind, 12-month, parallel-group study. • Men aged ≥ 50 years with a(More)
OBJECTIVE To investigate the effect of dutasteride and tamsulosin as combined therapy compared with each monotherapy for improving patient-reported health outcomes in men with moderate-to-severe urinary symptoms and prostate enlargement, reporting the pre-planned 2-year analyses from the CombAT trial. PATIENTS AND METHODS The CombAT study is an ongoing,(More)
Ranitidine 150 mg twice daily (BID) is an approved therapeutic approach for relieving the symptoms of gastroesophageal reflux disease. Ranitidine 150 mg four times daily (QID) and cimetidine 800 mg BID are indicated for endoscopically diagnosed erosive esophagitis. This 12-week, randomized, multicenter trial involving 696 patients compared ranitidine 150 mg(More)
Although ethnicity-based differences in prostate size and physiology have been reported, results of benign prostatic hyperplasia (BPH) treatment trials in predominantly Caucasian patients are assumed to be applicable to non-Caucasian populations. This post hoc analysis investigated whether an Asian subpopulation of men with moderate-to-severe BPH in the(More)
