Special warnings
Neurological Disorders
Extrapyramidal disorders may occur, particular in children and young adults, and/or when high doses are used.
These reactions occur usually at the beginning of the treatment and can occur after a single administration. Metoclopramide should be discontinued immediately in the event of extrapyramidal symptoms. These effects are generally completely reversible after treatment discontinuation, but may require a symptomatic treatment (benzodiazepines in children and/or anticholinergic anti-Parkinsonian medicinal products in adults).
Prolonged treatment with metoclopramide may cause tardive dyskinesia, potentially irreversible, especially in the elderly. Treatment should not exceed 3 months because of the risk of tardive dyskinesia. Treatment must be discontinued if clinical signs of tardive dyskinesia appear.
Neuroleptic malignant syndrome has been reported with metoclopramide in combination with neuroleptics as well as with metoclopramide monotherapy. Metoclopramide should be discontinued immediately in the event of symptoms of neuroleptic malignant syndrome and appropriate treatment should be initiated.
Special care should be exercised in patients with underlying neurological conditions and in patients being treated with other centrally-acting drugs
Symptoms of Parkinson's disease may also be exacerbated by metoclopramide.
Methaemoglobinemia
Methemoglobinemia which could be related to NADH cytochrome b5 reductase deficiency has been reported. In such cases, metoclopramide should be immediately and permanently discontinued and appropriate measures initiated (such as treatment with methylene blue).
Cardiac Disorders
There have been reports of serious cardiovascular undesirable effects including cases of circulatory collapse, severe bradycardia, cardiac arrest and QT prolongation following dministration of metoclopramide by injection, particularly via the intravenous route.
Special care should be taken when administering metoclopramide, particularly via the intravenous route to the elderly population, to patients with cardiac conduction disturbances (including QT prolongation), patients with uncorrected electrolyte imbalance, bradycardia and those taking other drugs known to prolong QT interval.
Intravenous doses should be administered as a slow bolus (at least over 3 minutes) in order to reduce the risk of adverse effects (e.g. hypotension, akathisia).
Renal and Hepatic Impairment
In patients with renal impairment or with severe hepatic impairment, a dose reduction is recommended.

Symptoms
Extrapyramidal disorders, drowsiness, decreased level of consciousness, confusion, hallucination, and cardio-respiratory arrest may occur.
Management
In case of extrapyramidal symptoms related or not to overdose, the treatment is only symptomatic (benzodiazepines in children and/or anticholinergic anti-parkinsonian medicinal products in adults).
A symptomatic treatment and a continuous monitoring of the cardiovascular and respiratory functions should be carried out according to clinical status.

Metoclopramide is a substituted benzamide. It is used among other things because of its anti-emetic properties. The anti-emetic effect is the result of two mechanisms of action involving the central nervous system:
- antagonism of the dopaminergic D2 receptors in the chemoreceptor trigger zone and in the vomiting centre of the medulla which is affected in apomorphine-induced vomiting;
- antagonism of the serotoninergic 5HT3 receptors and agonist effect on the 5HT4 receptors which are affected in chemotherapy-induced vomiting.
In addition to the central action, metoclopramide has a stimulant effect on gastrointestinal motility via a peripheral mechanism of action. There is an antidopaminergic effect and potentiation of the effect of acetylcholine. This causes accelerated emptying of the stomach and there is an increase in the pressure exerted by the lower oesophageal sphincter. Metoclopramide has no effect on gastric secretions.
Metoclopramide Mercury hydrochloride is an anti-emetic and an accelerator of gastric emptying.
Following oral administration the relative bioavailability compared with intravenous administration is 60 to 100%. Peak plasma concentrations are reached within 0.5 to 2 hours.
The distribution volume is 2-3 l/kg; 13-22% is bound to plasma proteins. Metoclopramide is excreted primarily in the urine, both in unchanged form and in sulfate or glucuronide conjugate form. The principal metabolite is an N-4 sulphur conjugate.
The plasma elimination half-life is 5 to 6 hours, irrespective of the route of administration.
Special patient populations
Renal impairment
The clearance of metoclopramide is reduced by up to 70% in patients with severe renal impairment, while the plasma elimination half-life is increased (approximately 10 hours for a creatinine clearance of 10-50 mL/minute and 15 hours for a creatinine clearance <10 mL/minute).
Hepatic impairment
In patients with cirrhosis of the liver, accumulation of metoclopramide has been observed, associated with a 50% reduction in plasma clearance.
Renal impairment
The clearance of Metoclopramide Mercury is reduced by up to 70% in patients with severe renal impairment, while the plasma elimination half-life is increased (approximately 10 hours for a creatinine clearance of 10-50 mL/minute and 15 hours for a creatinine clearance <10 mL/minute).
Hepatic impairment
