| Abstract | Objective To assess the role of dutasteride in preventing clinical progression of benign prostatic hyperplasia in asymptomatic men with larger prostates. Design Post hoc analysis of four year, double blind Reduction by Dutasteride of Prostate Cancer Events (REDUCE) study Participants 1617 men randomised to dutasteride or placebo with a prostate size >40 mL and baseline International Prostate Symptom Score (IPSS) <8. Subjects who took medications for benign prostatic hyperplasia were excluded at study entry. Interventions Placebo or dutasteride 0.5 mg daily. Main outcome measures Comparison of risk of clinical progression of benign prostatic hyperplasia at four years (defined as a ≥4 point worsening on IPSS, acute urinary retention, urinary tract infection, or surgery related to benign prostatic hyperplasia). Results 825 participants took placebo, 792 took dutasteride. A total of 464 (29%) experienced clinical progression benign prostatic hyperplasia, 297(36%) taking placebo, 167 (21%) taking dutasteride (P<0.001). The relative risk reduction was 41% and the absolute risk reduction 15%, with a number needed to treat (NNT) of 7. Among men who had acute urinary retention and surgery related to benign prostatic hyperplasia, the absolute risk reduction for dutasteride was 6.0% and 3.8%, respectively. On multivariable regression analysis adjusting for covariates, dutasteride significantly reduced clinical progression of benign prostatic hyperplasia with an odds ratio of 0.47 (95% CI 0.37 to 0.59, P<0.001). Analysis of time to first event yielded a hazard ratio of 0.673 (P<0.001) for those taking dutasteride. Sexual adverse events were most common and similar to prior reports. Limitations Further prospective studies may be warranted to demonstrate generalisability of these results. Conclusions This study is the first to explore the benefit of treating asymptomatic or mildly symptomatic men with an enlarged prostate. Dutasteride significantly decreased the incidence of benign prostatic hyperplasia clinical progression. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
