Final answer:
A 75-year-old man with symptomatic benign prostatic hyperplasia (BPH) should not be prescribed Amitriptyline because it can exacerbate urinary retention, an issue already present in BPH due to the constriction of the urethra.
Step-by-step explanation:
A 75-year-old man with symptomatic benign prostatic hyperplasia (BPH) should not be prescribed Amitriptyline. Amitriptyline is a tricyclic antidepressant that can exacerbate urinary retention by causing anticholinergic effects, which might worsen the symptoms of BPH. This medication could lead to increased difficulty in urination, increased risk of urinary tract infections, or contribute to acute urinary retention, all of which could seriously affect the health and quality of life of a patient with BPH. Considering BPH causes constriction of the urethra and can lead to difficulty in urination, it is important to avoid medications that could further impair the ability to urinate.
Drugs such as Enalapril, an ACE inhibitor, Atenolol, a beta-blocker, and Furosemide, a loop diuretic, are not typically contraindicated in BPH; however, particular care must be taken as each individual's overall health condition must be considered when prescribing medications.
