Potentially Fatal: Neuroleptic malignant syndrome; cardiac conduction disorders may occur with IV dosage form.

Drug Interactions

Increased sedative effects with CNS depressants. GI effects antagonised by antimuscarinics and opioids. Reduces absorption of digoxin. Increases absorption of ciclosporin, levodopa, aspirin, paracetamol. Interferes with hypoprolactinaemic effect of bromocriptine. Inhibits serum cholinesterase and prolongs neuromuscular blockade produced by suxamethonium and mivacurium. Potentially Fatal: Serotonin syndrome with sertraline (SSRI).

Contraindications

GI haemorrhage, mechanical obstruction and perforation; phaeochromocytoma; history of seizures

Mechanism of Action

Metoclopramide enhances the motility of the upper GI tract and increases gastric emptying without affecting gastric, biliary or pancreatic secretions. It increases duodenal peristalsis which decreases intestinal transit time, and increases lower oesophageal sphincter tone. It is also a potent central dopamine-receptor antagonist and may also have serotonin-receptor (5-HT3) antagonist properties. Absorption: Rapidly and almost completely absorbed from the GI tract (oral); peak plasma concentrations after 1-2 hr. Distribution: Widely distributed; crosses the blood-brain barrier and placenta; enters breast milk. Metabolism: Extensively hepatic. Excretion: Via urine (as unchanged drug, sulfate or glucuronide conjugates and metabolites), faeces; 4-6 hr (terminal elimination half-life).

Special Precautions

Children, elderly. Renal or hepatic impairment, porphyria, epilepsy, Parkinson's disease, history of depression. Ability to drive or operate machineries may be impaired. Pregnancy and lactation. Monitor patients on prolonged therapy. Increased risk of tardive dyskinesia in patients on prolonged or high-dose treatment.
