Metoclopramide is a psychotropic benzamide struc- turally related to the atypical antipsychotic drug sul- piride and the antiarrhythmic compound procainamide (Fig. 1).
What class of drug is metoclopramide?
Metoclopramide is in a class of medications called prokinetic agents. It works by speeding the movement of food through the stomach and intestines.
Can metoclopramide be used as an antipsychotic?
In clinical studies using low doses or dubious measures, it was considered not to be efficacious as an antipsychotic. We now find that it indeed has a clinical profile similar to known neuroleptics when used in a dose range predicted from animal models.
Can metoclopramide cause psychosis?
Chronic administration of a dopamine antagonist (e.g., metoclopramide) might induce dopamine receptor supersensitivity. It is hypothesized that exacerbation or occurrence of psychotic symptoms following neuroleptic withdrawal results from mesolimbic dopamine supersensitivity.
How an antipsychotic became widely used as an antiemetic?
First-generation antipsychotics were known to be effective antiemetics through dopamine D2 blockade, but their extrapyramidal symptoms made them a choice of last resort. One of the most powerful known antiemetics, ondansetron, targeted serotonin 5-HT3 receptors in the gut.
Who should not take metoclopramide?
You also should not use metoclopramide if you’ve had stomach or intestinal problems (a blockage, bleeding, or a hole or tear), epilepsy or other seizure disorder, or an adrenal gland tumor (pheochromocytoma). NEVER USE METOCLOPRAMIDE IN LARGER AMOUNTS THAN RECOMMENDED, OR FOR LONGER THAN 12 WEEKS.

Metoclopramide is also used to treat heartburn for patients with gastroesophageal reflux disease (GERD).
Which antipsychotic medications have antiemetic effects?

- feeling restless;
- feeling drowsy or tired;
- lack of energy;
- nausea, vomiting;
- headache, confusion; or.
- sleep problems (insomnia).
How does metoclopramide cause tardive dyskinesia?
Tardive dyskinesia may represent an idiosyncratic response to metoclopramide; pharmacogenetics affect pharmacokinetic and dopamine receptor pharmacodynamics in response to neuroleptic agents that cause similar neurological complications.
Can metoclopramide cause anxiety?
Metoclopramide has been implicated in the induction of anxiety symptoms in a single case report so far in the literature. In the patient described there, panic and agoraphobia occurred several weeks after taking metoclopramide subsequent to an akathisia.
Does metoclopramide make you poop?
Does Metoclopramide Make You Constipated? It’s not confirmed if Metoclopramide causes constipation. A more common side effect of this medication is diarrhea or other symptoms that may upset your stomach after taking it.

It has favorable rates of weight gain and fatigue and is the only atypical antipsychotic with evidence to improve cognition in bipolar disorder, based on a small controlled trial in euthymic bipolar I patients.
What makes an antipsychotic typical?
It is based on the view that second-generation antipsychotics (SGAs) have atypical properties, such as a low risk of extrapyramidal symptoms (EPS). Drugs that do not have atypical properties are considered typical or conventional antipsychotics.
