This study aims to investigate the effect of domperidone on gastric emptying and appetite sensations in healthy subjects. Domperidone is a dopamine 2 (D2) receptor antagonist with claims of gastrointestinal tract pro-kinetic activity. Accelerated gastric emptying (GE) may lead to reduced satiation, increased food intake and is associated with obesity and diabetes mellitus. It is hypothesized that domperidone will increase gastric emptying rate and reduce satiety responses to a high-fat meal.
