Pharmacy Technician Certification Exam Practice Question
Which of the following medications is contraindicated with nitroglycerin?
Correct Answer: B
Rationale: Nitroglycerin, a medication used to treat angina, can cause a significant drop in blood pressure when combined with sildenafil, a phosphodiesterase type 5 inhibitor used for erectile dysfunction. This interaction can lead to serious cardiovascular complications.
Amoxicillin, a common antibiotic, does not interact negatively with nitroglycerin, making it safe to use together. Levothyroxine, a thyroid hormone replacement, and metformin, used for diabetes management, also do not pose any contraindications with nitroglycerin. Thus, while options A, C, and D are safe, option B presents a critical risk.
