Tamsulosin ((R)-(-)-YM12617 free base) is an alpha1A adrenergic receptor antagonist used for the symptomatic treatment of benign prostatic hyperplasia (BPH). It treats difficulty urinating, a common symptom of an enlarged prostate, by relaxing the neck muscles of the bladder and muscle fibers in the prostate itself, easing urination.
