Correct Answer is D
Explanation
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.
Correct Answer is C
Explanation
A. Hypotension: Hypotension is not a common interaction between oxybutynin and haloperidol.
B. Lowered plasma concentrations: There is no significant interaction that would lead to lowered plasma concentrations of either medication.
C. Increased effect of the antispasmodic drug: Both oxybutynin and haloperidol have anticholinergic properties. When combined, these properties can increase the risk of anticholinergic side effects, such as dry mouth, constipation, and urinary retention, enhancing the effect of oxybutynin.
D. Decreased effect of the antipsychotic drug: There is no evidence that oxybutynin would decrease the effect of haloperidol.
