Treatment of GORD
Increases gastric emptying - 4ActionStimulates motility of upper GI tract and increases lower oesophageal sphincter tone and blocks dopamine receptors at chemoreceptor trigger zone.
Decreases reflux into the oesophagus by increasing the resting pressure of the lower esophageal sphincter and improves acid clearance from the esophagus by increasing amplitude of esophageal peristaltic contractions
Accelerates intestinal transit and gastric emptying by preventing relaxation of gastric body and increasing the phasic activity of antrum - 5Absorption & distributionABSORPTION:GIT
DISTRIBUTION: Distributed to most body tissues and fluids, including the brain. Drug crosses the placental barrier and is distributed in breast milk. - 6Metabolism & excretionMETABOLISM + EXCRETION: Not metabolized extensively; a small amount is metabolized in the liver via conjugation. Excreted in urine and faeces.

CNS depressants - avoid use together due to additive CNS effects
Digoxin - dec. absorbtion of digoxin from stomach. Monitor.
Paracetamol, levodopa, tetracyline - accelerated absorption of drugs from small bowel. Monitor. - 11AssessmentsBlood pressure
Alertness
