OMEEBEST-D CAP S/ST
OMEPRAZOLE 20MG + DOMPERIDONE 10MG
OMEEBEST-D CAP S/ST is a capsule combining omeprazole 20 mg with domperidone 10 mg, pairing a proton pump inhibitor with a prokinetic. It is used for gastro-oesophageal reflux, acid dyspepsia and reflux accompanied by nausea, bloating or a sensation of fullness.
01
Benefits
- Omeprazole blocks the gastric proton pump, producing sustained acid suppression that heals oesophagitis and relieves reflux.
- Domperidone increases gastric emptying and lower oesophageal sphincter tone, reducing the reflux itself rather than only its acidity.
- The prokinetic action relieves the nausea, bloating and early fullness that acid suppression alone does not address.
- Particularly useful in reflux associated with delayed gastric emptying, including diabetic gastroparesis.
- One capsule replaces two separate medicines.

03
Precautions
- Domperidone prolongs the QT interval and has been associated with serious arrhythmia and sudden cardiac death. Contraindicated in known QT prolongation, electrolyte disturbance and underlying cardiac disease; use at the lowest effective dose for no more than about a week.
- Contraindicated alongside other QT-prolonging drugs and strong CYP3A4 inhibitors including ketoconazole, erythromycin and clarithromycin.
- Contraindicated in gastrointestinal haemorrhage, mechanical obstruction or perforation, and in prolactin-releasing pituitary tumour.
- Take thirty to sixty minutes before food; a proton pump inhibitor taken after a meal is substantially less effective.
- Long-term proton pump inhibitor use is associated with low magnesium and vitamin B12, fracture risk and enteric infection. Review the need periodically.
- Omeprazole reduces the effect of clopidogrel — discuss an alternative in patients on it.
- Alarm features — weight loss, difficulty swallowing, vomiting blood, black stools, anaemia — need investigation before starting acid suppression.
