Domperidone Tablets contain domperidone as the active ingredient, which belongs to a group of medicines called ‘dopamine antagonists’. This medicine is used to treat nausea (feeling sick) and vomiting (being sick) in adults and adolescents (12 years of age and older and weighing 35 kg or more).
Domperidone is a dopamine antagonist (blocking both D1 and D2 receptors) Dopamine antagonism stimulates gastric emptying, increased rate of intestinal transit time and enhanced strength of oesophageal sphincter contractions. The antiemetic effect of domperidone is due to the prokinetic effect on the gastrointestinal tract combined with antagonisation of dopamine receptors in the chemo trigger zone (CTZ). Domperidone does not readily cross the blood brain barrier.
