PRODUCT INTRODUCTION
description
Tamsulosin is a 5-(2-{[2-(2-ethoxyphenoxy)ethyl]amino}propyl)-2-methoxybenzenesulfonamide that has (R)-configuration. A specific alpha1 adrenoceptor antagonist used (generally as its hydrochloride salt, tamsulosin hydrochloride) in the treatment of prostatic hyperplasia, chronic prostatitis, urinary retention, and help with the passage of kidney stones. It has a role as an alpha-adrenergic antagonist and an antineoplastic agent. It is a conjugate base of a tamsulosin(1+). It is an enantiomer of an ent-tamsulosin.
