This article reports the results of a post hoc analysis of the multicenter, randomized, double-blind Combination of Avodart and Tamsulosin (CombAT) study, which aimed to investigate the effects of dutasteride (0.5 mg), tamsulosin (0.4 mg), and their combination on storage and voiding symptoms in 4844 men aged ≥ 50 years with moderate-to-severe lower urinary tract symptoms (International Prostate Symptom Score ≥ 12), prostate volume (PV) ≥ 30 cm3 and PSA 1.5-10 ng ml-1. After 24 months, combination treatment achieved significantly greater mean reductions in both voiding and storage symptoms than either monotherapy, in each of the three baseline PV tertiles (30 to <42, 42 to <58, ≥ 58 cm3). Dutasteride was as effective as tamsulosin for control of storage symptoms, but provided significantly greater relief of voiding symptoms than tamsulosin.
