Question

Quizplus · Accepted Answer

Tamsulosin (Flomax) selectively blocks alpha-1 adrenergic receptors, particularly subtype alpha-1A receptors, which are abundant in the prostate gland. This produces smooth muscle relaxation in the prostate and bladder neck, improving urine flow in men with BPH. Choice A best reflects the specific alpha-1 receptor subtype targeted by tamsulosin.
