🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine combines two active ingredients with complementary mechanisms. Domperidone is a peripheral dopamine D2 receptor antagonist that acts on the chemoreceptor trigger zone and the gastrointestinal tract. By blocking D2 receptors, it enhances gastric and duodenal peristalsis, accelerates gastric emptying, and increases lower esophageal sphincter tone, thereby reducing nausea, vomiting, and reflux. Ranitidine is a competitive histamine H2-receptor antagonist that binds to H2 receptors on gastric parietal cells, reducing both basal and stimulated gastric acid secretion. Together, they address both motility and acid-related components of upper gastrointestinal disorders.
Mechanism Steps
💡 How to Take gastidom 15mg/150mg tablet
Strength: Each tablet contains Domperidone 15 mg and Ranitidine 150 mg.
Dosage Information
| Adult Dosage | The usual adult dose is one tablet taken orally before meals, typically twice daily or as directed by your doctor. The exact dose and frequency depend on the condition being treated, your age, kidney and liver function, and other medications you are taking. Dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function. Do not self-adjust the dose. |
| Pediatric Dosage | Pediatric dosing is not established from available information. Consult a pediatrician. |
| Elderly Dosage | Elderly patients may require a lower dose due to reduced renal and hepatic function. Dose must be individualized by a qualified clinician. |
| Renal Impairment | In patients with severe renal impairment (creatinine clearance <30 mL/min), ranitidine dose should be reduced. Domperidone should be used with caution. Consult your doctor for dose adjustment. |
| Hepatic Impairment | In patients with hepatic impairment, domperidone should be used with caution due to extensive hepatic metabolism. Ranitidine dose may need adjustment. Consult your doctor. |
| Maximum Daily Dose | The maximum recommended daily dose is 30 mg domperidone and 300 mg ranitidine (i.e., two tablets per day). Do not exceed without medical advice. |
