Metoclopramide Hydrochloride Noridem Enterprises (Metoclopramide Hydrochloride Monohydrate)

Metoclopramide Hydrochloride is used in the antiemetic and gastroprokinetic therapeutic area to manage disorders of nausea, vomiting and gastric motility.

• Nausea and vomiting: reduces the frequency and intensity of acute and delayed emesis in adult patients.
• Gastroparesis: accelerates gastric emptying, relieving symptoms such as early satiety and bloating.
• Post‑operative nausea and vomiting (PONV): prevents or treats emesis following surgical procedures.
• Chemotherapy‑induced nausea and vomiting (CINV): mitigates both acute and delayed nausea associated with cytotoxic therapy.

• Metoclopramide Hydrochloride blocks dopamine D2 receptors in the chemoreceptor trigger zone and throughout the gastrointestinal tract, diminishing the central stimulus for vomiting. It also antagonizes 5‑HT3 receptors and agonises 5‑HT4 receptors, which together enhance gastric motility and accelerate gastric emptying, thereby reducing nausea and vomiting.

Metoclopramide Hydrochloride may cause a range of adverse reactions.

Common Side Effects

• Drowsiness: mild sedation or fatigue.
• Restlessness: feelings of inner tension or akathisia.
• Diarrhea: loose stools or increased bowel movements.

Serious or Rare Side Effects

• Extrapyramidal symptoms: dystonia, tremor, or rigidity.
• Tardive dyskinesia: irreversible involuntary movements with long‑term use.
• Neuroleptic malignant syndrome: rare but life‑threatening hyperthermia and muscle rigidity.
• Severe allergic reactions: anaphylaxis, rash, or angioedema.
• Hyperprolactinemia: galactorrhea or menstrual disturbances.

Before initiating therapy, clinicians should evaluate patient‑specific risk factors and monitor for known adverse effects.

• Renal or hepatic impairment: adjust monitoring as drug clearance may be reduced.
• Extrapyramidal risk: observe for signs of dystonia or tardive dyskinesia, especially with prolonged use.
• Hypersensitivity: discontinue if allergic reactions occur.
• Elderly patients: use caution due to increased susceptibility to sedation and falls.
• Concomitant dopamine‑blocking agents: assess for additive effects.
• Store at 2-8°C: keep refrigerated, protect from light, do not freeze or shake.

Metoclopramide Hydrochloride can interact with several drug classes, requiring careful management.

Major Interactions (Avoid)

• CNS depressants: may enhance sedation and respiratory depression.
• Anticholinergic agents: increase risk of severe extrapyramidal reactions.
• MAO inhibitors: potential for hypertensive crisis.

Moderate Interactions (Monitor Closely)

• Opioids: may exacerbate reduced gastrointestinal motility.
• SSRIs or other serotonergic drugs: raise the possibility of serotonin syndrome.
• CYP2D6 inhibitors: can alter metoclopramide plasma levels, affecting efficacy and safety.
