Which of the following is NOT a drug that can worsen BPH symptoms?

Caffeine
Diuretics
Calcium channel blockers
SNRIs

The correct answer is: Calcium channel blockers

Calcium channel blockers (Option C) are not known to worsen symptoms of benign prostatic hyperplasia (BPH). In fact, some alpha-blockers like doxazosin are used to treat BPH by relaxing smooth muscle in the prostate and bladder neck. On the other hand, choices A, B, and D (caffeine, diuretics, and SNRIs) can potentially worsen BPH symptoms. Caffeine can irritate the bladder and increase urinary frequency. Diuretics can lead to increased urine production, possibly aggravating BPH symptoms. SNRIs (serotonin-norepinephrine reuptake inhibitors) can have adverse effects on urinary function, including urinary retention and problems with urination.
