Tamsulosin MR and OCAS (modified release and oral controlled absorption system): current therapeutic uses.
BACKGROUND
Although tamsulosin is mainly used to treat lower urinary tract symptoms secondary to benign prostatic hyperplasia, with better understanding of functional anatomy and distribution of alpha(1) receptors, it is also indicated in other conditions of genito-urinary tract in both men and women.


OBJECTIVE
To detail the therapeutic use and clinical effects of tamsulosin.


METHODS
The scope of the review was related to tamsulosin and its therapeutic application in conditions of genitourinary tract. Publications were searched from Pubmed and Medline from 1975 to 2007 using the search words tamsulosin, lower urinary tract symptoms, alpha receptors and blockers.


CONCLUSIONS
The management of benign prostatic hyperplasia was transurethral resection of prostate until simpler and alternative treatments were tried in the last two decades, particularly alpha(1) adrenoceptor-blocking agents. Tamsulosin is a potent, third-generation selective alpha(1A) adrenoceptor-blocking agent.
