Key takeaways
Emend (aprepitant) and Reglan (metoclopramide) are both used to manage nausea and vomiting, but they work in different ways and are used for different conditions. Emend (aprepitant) is a neurokinin 1 (NK1) receptor antagonist that prevents nausea and vomiting caused by chemotherapy, while Reglan (metoclopramide) is a dopamine antagonist used to treat gastroesophageal reflux disease (GERD) and diabetic gastroparesis. Emend is taken for a short period (three days) during chemotherapy cycles, whereas Reglan is taken multiple times a day for up to three months. Emend is available as capsules and oral suspension, while Reglan comes in various forms, including tablets, liquid, and nasal spray. Reglan has a black box warning for tardive dyskinesia, a serious movement disorder, making it less favorable for long-term use. Emend, on the other hand, has many drug interactions but does not carry the same severe risk of movement disorders. Both medications are available in generic forms, making them more affordable options.
