Question 1 of 5
A 53-year-old man presented to the clinic complaining of itching, flushing, arthralgia, heartburn, and diarrhea. Further exams led to the diagnosis of systemic mastocytosis. Which of the following pairs of drugs should be included in the therapeutic treatment of this patient?
Correct Answer: C
Rationale: The correct answer is C: Loratadine and famotidine. Loratadine is an antihistamine that can help alleviate itching and flushing by blocking the action of histamine released during mast cell activation. Famotidine is a histamine H2 receptor antagonist that can reduce heartburn symptoms by decreasing stomach acid production. Misoprostol (choice B) is used to prevent ulcers but is not directly related to mastocytosis treatment. Aspirin and ergotamine (choice A) can worsen symptoms in mastocytosis patients due to their potential to trigger mast cell degranulation. Diphenhydramine (choice D) is an antihistamine but is not as effective as loratadine in controlling symptoms of mastocytosis. Therefore, the best therapeutic approach for this patient is to use loratadine and famotidine to manage his symptoms effectively.
