In the described postoperative regimen, which drug is the antiemetic?

• A. Co-codamol
• B. Dalteparin
• C. Metoclopramide
• D. Sinemet

Answer: (C)

Antiemetic action in postoperative care involves drugs that prevent nausea and vomiting after surgery. Metoclopramide fits here because it blocks dopamine D2 receptors in the chemoreceptor trigger zone and has prokinetic effects, which speeds gastric emptying. This combination helps prevent postoperative nausea and vomiting, a common issue after anesthesia and opioids. The other drugs serve different roles: co-codamol is an analgesic, dalteparin is an anticoagulant, and Sinemet (levodopa/carbidopa) is used for Parkinson’s disease, none of which are antiemetic.
