Tamsulosin hydrochloride((R)-(-)-YM12617;LY253351) is a selective α1 receptor antagonist. Target: α1 receptor Tamsulosin is a selective α1 receptor antagonist that has preferential selectivity for the α1A receptor in the prostate versus the α1B receptor in the blood vessels. Tamsulosin-treated patients had a 0.30-fold lower risk of developing acute urinary retention compared with control patients. None of the International Continence Society male questionnaire domain scores showed significant changes between the groups [1]. tamsulosin can be recommended for treating men after catheterization for AUR, and can reduce the likelihood of the need for re-catheterization [2].
