Tamsulosin hydrochloride(Cas 106463-17-6) Usage

Therapeutic Function

Antihypertensive

Hazard

Moderately toxic by ingestion.

Biological Activity

Selective α 1A -adrenoceptor antagonist (pK i values are 9.97, 9.64 and 8.86 for α 1A , α 1B and α 1D subtypes respectively). Decreases resting maximal urethral pressure with negligable effect on mean arterial blood pressure in vivo .

Biochem/physiol Actions

Tamsulosin is an α1A/1D-adrenoceptor antagonist used as a treatment of benign prostatic hypertrophy (BPH). Its activity as an ? blocker also affects the iris, and has led to complications during cataract surgery, a condition called "floppy iris" syndrome.

General Description

Tamsulosin hydrochloride is a subtypeselective a1A and a1D adrenoceptor antagonist, which exists in two enantiomeric forms, of which the R-isomer is the pharmaceutically active component. It is used to reduce urinary obstruction and is also involved in relieving the symptoms associated with symptomatic benign prostatic hyperplasia.
