Which of the following is a common use for doxazosin in the treatment of benign prostatic hyperplasia (BPH)?
To reduce the size of the prostate gland
To increase testosterone levels
To treat urinary tract infections
To relax the smooth muscles in the bladder neck and prostate
The Correct Answer is D
A. To reduce the size of the prostate gland: Doxazosin does not reduce the size of the prostate; it works by relaxing smooth muscle to improve urinary flow.
B. To increase testosterone levels: Doxazosin does not affect testosterone levels; it is an alpha-blocker that helps with urinary symptoms of BPH.
C. To treat urinary tract infections: Doxazosin is not used for treating infections; it addresses symptoms related to BPH.
D. To relax the smooth muscles in the bladder neck and prostate: This is correct. Doxazosin is an alpha-1 adrenergic blocker that helps relax smooth muscles in the prostate and bladder neck, improving urine flow and relieving symptoms of BPH.
