A 36-year-old woman with no significant medical history presents with a four-week history of epigastric pain. The pain tends to occur two hours after meals. She has lost 4 pounds over the last four weeks. She is allergic to azithromycin and clarithromycin. A urea breath test detects radiolabeled carbon dioxide in exhaled breath. Two days after starting definitive treatment, she returns to the hospital with flushing, headaches, nausea and vomiting after having a few beers that night. What is the mechanism of the drug involved in the adverse reaction?
