What is a possible side effect of metoclopramide?

• A. Hypertension
• B. Dystonia
• C. Diarrhea
• D. Weight gain

Answer: (B)

Metoclopramide is a medication primarily used to treat nausea, vomiting, and gastric reflux by enhancing gastrointestinal motility. One significant side effect associated with metoclopramide is dystonia, which refers to sustained muscle contractions, abnormal postures, or involuntary movements. This side effect is often due to the drug's dopaminergic antagonism, which can lead to an imbalance of dopamine in various brain pathways, particularly those involved in motor control. Dystonia can manifest as acute symptoms, which may occur after a single dose or after prolonged use, and it may sometimes require treatment with anticholinergic agents. The risk of developing dystonic reactions is particularly increased in younger populations and in patients on higher doses of the medication. While metoclopramide can lead to gastrointestinal disturbances, including diarrhea, and may be associated with other symptoms like weight gain in some patients due to increased gastric motility, these are not as commonly discussed or emphasized compared to the risk of movement disorders such as dystonia. Hypertension is not typically recognized as a side effect of metoclopramide, and although it is not common, any drug has the potential for varied side effects among different individuals.
