Reglan is categorized as what type of medication?

• A. Antiemetic
• B. Antacid
• C. Prokinetic
• D. Antihistamine

Answer: (C)

Reglan is best described as a prokinetic drug, meaning it speeds up movement through the upper digestive tract. It achieves this by blocking dopamine D2 receptors in the gut (and in the brain’s chemoreceptor trigger zone), which increases acetylcholine release and enhances peristalsis and gastric emptying. This prokinetic effect is its defining clinical action, useful for conditions like gastroparesis and related nausea from slowed gastric motility. While it does have antiemetic effects due to the same D2 blockade in the brain, the primary way it’s categorized is as a prokinetic. It isn’t an antacid, and it isn’t an antihistamine, so those choices don’t fit as the main classification.
