Summary of Clinical Use Click here for help
Used in the symptomatic relief of benign prostatic hyperplasia.
A 2015 report indicates that tamsulosin increases expulsion of larger (>10mm) kidney stones [4] in a double-blind, placebo-controlled, randomized, multicenter clinical trial. This result suggests that terazosin and doxazosin, which belong to the same drug class, may provide the same effect.
Mechanism Of Action and Pharmacodynamic Effects Click here for help
Selective antagonist for α1A- and α1D-adrenoceptors in the prostate, prostatic capsule, prostatic uretha and bladder neck causing relaxation of smooth muscles and therefore decreasing urinary outflow resistance in men.
