Metoclopramida Basi (Metoclopramide Hydrochloride Monohydrate)

Metoclopramide acts on the chemoreceptor trigger zone and gastrointestinal tract to alleviate nausea‑related disorders.

• Nausea and vomiting: reduces frequency and severity of episodes in adults.
• Post‑operative nausea and vomiting: prevents or treats nausea after surgery.
• Gastroparesis: improves gastric emptying and symptom relief.
• Migraine‑associated nausea: alleviates nausea accompanying migraine attacks.

• Metoclopramide blocks dopamine D2 receptors in the chemoreceptor trigger zone, diminishing the vomiting reflex. It also antagonizes 5‑HT3 receptors and stimulates 5‑HT4 receptors, which together increase acetylcholine release in the gut, promoting coordinated gastric contractions and accelerating gastric emptying. The drug’s central D2 antagonism also reduces stimulation of the vomiting centre, while peripheral 5‑HT4 agonism enhances peristalsis, resulting in faster transit of gastric contents.

Metoclopramide may cause a range of adverse reactions, varying from mild to severe.

Common Side Effects

• Drowsiness: may cause sleepiness or reduced alertness.
• Fatigue: feeling of tiredness.
• Restlessness: inner sense of unease or agitation.
• Diarrhea: loose stools.
• Dry mouth: reduced salivation.

Serious or Rare Side Effects

• Extrapyramidal symptoms: involuntary muscle movements, especially in the neck and face.
• Tardive dyskinesia: persistent, potentially irreversible facial or limb movements.
• Neuroleptic malignant syndrome: rare life‑threatening reaction with fever and muscle rigidity.
• Depression or suicidal thoughts: mood changes requiring immediate attention.

When using Metoclopramida Basi, consider the following precautions.

• Assess renal function: adjust dose in renal impairment.
• Monitor for extrapyramidal symptoms: watch for muscle rigidity or tremor.
• Use lowest effective dose: limit duration to reduce risk of tardive dyskinesia.
• Avoid in known hypersensitivity: discontinue if allergic reaction occurs.
• Use caution in elderly: increased susceptibility to side effects.
• Store at room temperature: keep in original pack, protect from moisture.

Metoclopramida Basi can interact with several medicines; review patient medication lists.

Major Interactions (Avoid)

• Antipsychotics (e.g., haloperidol): may increase risk of extrapyramidal effects.
• MAO inhibitors: can potentiate central nervous system effects.
• CNS depressants (e.g., benzodiazepines): additive sedation.

Moderate Interactions (Monitor Closely)

• Opioids (e.g., morphine): may enhance nausea control but require dose adjustment.
• SSRIs (e.g., sertraline): potential for serotonin syndrome.
