๐ Rapco D 30 mg/20 mg Capsule Uses & Benefits
- This combination is primarily used for the management of gastroesophageal reflux disease (GERD) with associated dysmotility symptoms, such as heartburn, regurgitation, and nausea.
- It is also indicated for the treatment of functional dyspepsia, where both acid suppression and prokinetic effects are beneficial.
- Additionally, it may be used in the management of gastroparesis, particularly in diabetic patients, to improve gastric emptying and reduce symptoms like early satiety, bloating, and vomiting.
Off-label uses: Off-label uses include the treatment of chronic hiccups, cyclic vomiting syndrome, and as an adjunct in the management of refractory nausea and vomiting in palliative care. However, evidence for these uses is limited and should be considered only under specialist guidance.

๐ฌ Pharmacology (PK/PD)
Pharmacokinetics
How It Works
Domperidone is a peripheral dopamine D2 receptor antagonist that increases gastrointestinal motility by blocking inhibitory dopamine receptors in the gut. It enhances lower esophageal sphincter pressure, improves gastric emptying, and coordinates antral and duodenal contractions. Rabeprazole is a proton pump inhibitor that accumulates in the acidic environment of gastric parietal cells, where it is activated and irreversibly binds to the H+/K+ ATPase enzyme, inhibiting acid secretion. This dual action provides both symptomatic relief and healing of erosive esophagitis.

๐ก๏ธ Safety & Warnings
๐ซ Contraindications
Contraindicated in patients with known hypersensitivity to domperidone, rabeprazole, or any excipients. Also contraindicated in patients with gastrointestinal hemorrhage, mechanical obstruction, or perforation. Domperidone is contraindicated in patients with prolonged QT interval, significant electrolyte disturbances, or concomitant use of QT-prolonging drugs. Rabeprazole is contraindicated in patients with severe hepatic impairment.
๐ซ Contraindicated Diseases
- Gastrointestinal hemorrhage
- Mechanical obstruction
- Prolonged QT interval
- Severe hepatic impairment
โ ๏ธ Warnings & Precautions
Domperidone may cause QT prolongation and ventricular arrhythmias, especially at high doses or in patients with risk factors (e.g., electrolyte imbalance, bradycardia, concomitant QT-prolonging drugs). Use lowest effective dose and shortest duration. Rabeprazole may increase risk of Clostridium difficile infection, hypomagnesemia, and vitamin B12 deficiency with long-term use. Bone fracture risk may be increased with high-dose or prolonged PPI use. Monitor renal function and electrolytes periodically. Discontinue if signs of interstitial nephritis occur. Avoid abrupt discontinuation; taper if used long-term.
โ ๏ธ FDA Warning
FDA warns about increased risk of Clostridium difficile infection with PPIs and risk of QT prolongation with domperidone (not approved in USA).
๐ Monitoring Parameters
Monitor ECG in patients at risk for QT prolongation, serum electrolytes (especially potassium, magnesium), renal function, and signs of Clostridium difficile infection. Long-term use: monitor magnesium and vitamin B12 levels.
๐คฑ Lactation Safety
Domperidone is excreted in breast milk and may cause adverse effects in the infant. Rabeprazole is l
Additional Safety Advice
Avoid alcohol as it may worsen GERD and increase side effects.
Use only if clearly needed; consult doctor.
May cause dizziness; avoid driving if affected.
Contraindicated in severe liver disease; use with caution in moderate impairment.
No dose adjustment needed for mild-moderate impairment; caution in severe impairment.
Avoid spicy, fatty, and acidic foods; eat small frequent meals.
๐ Overdose Management
Overdose may cause extrapyramidal reactions (domperidone) and drowsiness, confusion, or blurred vision (rabeprazole). Treatment is symptomatic and supportive. Gastric lavage may be considered if ingestion is recent. Activated charcoal may reduce absorption. Monitor ECG for QT prolongation. Extrapyramidal symptoms may be treated with anticholinergic agents.
โฐ Missed Dose
Take the missed dose as soon as remembered. If it is almost time for the next dose, skip the missed dose and continue the regular schedule. Do not double the dose.
