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.

Application

Tamsulosin hydrochloride may be used as a pharmaceutical reference standard for the quantification of the analyte in pharmaceutical formulations using various chromatography techniques.
These Secondary Standards are qualified as Certified Reference Materials. These are suitable for use in several analytical applications including but not limited to pharma release testing, pharma method development for qualitative and quantitative analyses, food and beverage quality control testing, and other calibration requirements.

Biochem/physiol Actions

Tamsulosin is a α1A/1D-adrenoceptor antagonist; Used as a treatment of BPH (benign prostatic hypertrophy).
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.
