General information
Metoclopramide is prescribed to treat nausea and vomiting that results from many causes, including chemotherapy and various digestive disorders.
It is furthermore effective in relieving digestive symptoms such as acid reflux, indigestion and heartburn.
This medication enhances the speed at which the stomach is emptied. This is of particular use in migraine as metoclopramide enhances absorption and efficacy of painkillers (non-opioid). It is therefore often found in migraine cocktails that pharmacists make up. Caution is advised in patients under the age of 20; metoclopramide may cause muscle spasm in the face and neck.
How does metoclopramide work?
Metoclopramide lowers the effect of dopamine in the chemo-emetic trigger zone, thereby preventing messages from being sent to the vomiting centre of the brain. The result is a reduction in nausea and vomiting. It furthermore speeds the passage of food through the stomach into the intestine, which physically helps to prevent vomiting.
