Correct Answer is D
Explanation
Choice A rationale
Asthma is not a contraindication for sumatriptan. Sumatriptan is a selective serotonin receptor agonist used to treat migraines by constricting blood vessels in the brain. It does not have a significant impact on respiratory conditions like asthma.
Choice B rationale
Kidney disease is not a contraindication for sumatriptan. However, caution is advised when using sumatriptan in patients with severe renal impairment due to potential accumulation of the drug and its metabolites.
Choice C rationale
Rheumatoid arthritis is not a contraindication for sumatriptan. Sumatriptan’s mechanism of action does not interfere with the inflammatory processes involved in rheumatoid arthritis.
Choice D rationale
Coronary artery disease (CAD) is a contraindication for sumatriptan. Sumatriptan can cause vasoconstriction of coronary arteries, which can exacerbate CAD and increase the risk of myocardial infarction or other cardiac events.
