Metoclopramide Sandoz (Metoclopramide Hydrochloride)

Metoclopramide is employed to manage conditions that involve nausea, vomiting and delayed gastric emptying.

• Nausea and vomiting: reduces the frequency and severity of episodes.
• Post‑operative nausea and vomiting: prevents or treats nausea after surgery.
• Gastroparesis: enhances gastric motility and alleviates related symptoms.
• Gastro‑oesophageal reflux disease (GERD) adjunct: used alongside other agents to improve reflux control.

• Metoclopramide blocks dopamine D2 receptors in the chemoreceptor trigger zone and throughout the gastrointestinal tract, diminishing the neural stimulus for nausea and vomiting. By inhibiting D2 receptors it also increases acetylcholine release, promoting coordinated gastric contractions and accelerating gastric emptying. Weak antagonism of 5‑HT3 receptors adds to its antiemetic effect.

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

Common Side Effects

• Drowsiness: feeling unusually sleepy or fatigued.
• Fatigue: reduced energy and increased tiredness.
• Restlessness: an uneasy feeling or inability to stay still.
• Diarrhea: loose, frequent stools.

Serious or Rare Side Effects

• Extrapyramidal symptoms: dystonia, akathisia, or other movement disorders.
• Tardive dyskinesia: potentially irreversible involuntary movements with long‑term use.
• Neuroleptic malignant syndrome: rare but life‑threatening reaction with fever and muscle rigidity.
• Hyperprolactinemia: elevated prolactin causing galactorrhea or menstrual disturbances.

When prescribing Metoclopramide, clinicians should consider several safety measures.

• Assess neurological status: monitor for extrapyramidal symptoms, especially in the elderly.
• Limit duration: avoid use beyond 12 days to reduce risk of tardive dyskinesia.
• Use caution in renal impairment: dose adjustment may be required.
• Avoid in patients with known hypersensitivity to metoclopramide.
• Pregnancy and lactation: use only if benefits outweigh risks, as safety data are limited.
• Store at ambient temperature: keep below 25 °C, protect from moisture and light, retain in original packaging.

Metoclopramide can interact with other medicines, requiring attention to avoid adverse outcomes.

Major Interactions (Avoid)

• Anticholinergic agents: may diminish the prokinetic effect.
• CYP2D6 inhibitors (e.g., fluoxetine, paroxetine): increase metoclopramide plasma concentrations.
• Other dopamine antagonists (e.g., phenothiazines): additive risk of extrapyramidal symptoms.

Moderate Interactions (Monitor Closely)

• Opioids: may enhance constipation and sedation.
• Serotonergic agents (e.g., ondansetron): potential additive antiemetic effect but increased risk of serotonin syndrome.
