A patient with benign prostatic hypertrophy (BPH) has been prescribed terazosin (Hytrin). How do alpha-adrenergic blockers, such as terazosin, assist in treating the symptoms of BPH?
A) They increase gastric motility.
B) They increase skeletal muscle contraction.
C) They inhibit contraction of the urinary bladder.
D) They decrease blood pressure.
C
Feedback:
Alpha1-adrenergic blockers block postsynaptic alpha1-adrenergic receptors, which results in a dilation of arterioles and veins and a relaxation of sympathetic effects on the bladder and urinary tract. This action makes these drugs useful in the treatment of BPH. BPH is characterized by obstructed urine flow as the enlarged prostate gland presses on the urethra. Alpha1-blocking agents can decrease urinary retention and improve urine flow by relaxing muscles in the prostate and urinary bladder. Options A, B, and D are not correct.
