IV: Cardiac conduction disorders, transient flushing of face and upper body (high dose).

Introduction

Metoclopramide blocks dopamine receptors and in higher doses, it also blocks serotonin receptors in chemoreceptor trigger zone of the CNS. It enhances the response to acetylcholine of tissue in upper GI tract causing enhanced motility and accelerated gastric emptying w/o stimulating gastric, biliary, or pancreatic secretions. It also increases lower esophageal sphincter tone.

Antimet Precaution

Patients with underlying neurological conditions, cardiac conduction disturbances, uncorrected electrolyte imbalance, bradycardia. Renal and hepatic impairment. Elderly, childn. Pregnancy and lactation.

Interaction

Antagonistic effect with anticholinergics and morphine derivatives. Potentiation of sedative effects with CNS depressants. Additive effect with other neuroleptics on the occurrence of extrapyramydal disorders. May increase the risk of serotonin syndrome with serotonergic drugs (e.g. SSRIs). May decrease digoxin bioavailability. May increase ciclosporin bioavailability. May prolong the neuromuscular blocking effect of mivacurium and suxamethonium. Increased exposure levels with strong CYP2D6 inhibitors (e.g. fluoxetine). May reduce plasma concentration of atovaquone.

Pregnancy Lactation use

Category B: Either animal-reproduction studies have not demonstrated a foetal risk but there are no controlled studies in pregnant women or animal-reproduction studies have shown an adverse effect (other than a decrease in fertility) that was not confirmed in controlled studies in women in the 1st trimester (and there is no evidence of a risk in later trimesters).

Contraindication

GI haemorrhage, mechanical obstruction or GI perforation; confirmed or suspected pheochromocytoma; history of neuroleptic or metoclopramide-induced tardive dyskinesia; epilepsy, Parkinson's disease; history of methaemoglobinaemia with metoclopramide or of NADH cytochrome-b5 deficiency. Concomitant use with levodopa or dopaminergic agonists.

Special Warning
