🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionDomperidone is rapidly absorbed after oral administration, with peak plasma levels occurring within 30 to 60 minutes. Ranitidine is also rapidly absorbed, with peak levels in 1 to 3 hours. Food may slightly delay absorption but does not significantly affect the extent of absorption for either drug.
DistributionDomperidone is widely distributed in body tissues but does not readily cross the blood-brain barrier. Ranitidine distributes widely, including into breast milk and cerebrospinal fluid. Both drugs have moderate volumes of distribution.
Protein BindingDomperidone is approximately 91-93% bound to plasma proteins. Ranitidine is about 15% bound to plasma proteins.
MetabolismDomperidone undergoes extensive first-pass metabolism in the liver via CYP3A4 and CYP1A2 enzymes. Ranitidine is metabolized in the liver to N-oxide, S-oxide, and desmethyl metabolites, with the N-oxide being the major metabolite.
Half-LifeDomperidone: approximately 7-9 hours; Ranitidine: approximately 2-3 hours.
ExcretionDomperidone is excreted mainly in feces (about 66%) and urine (about 33%). Ranitidine is excreted primarily unchanged in urine (about 70%) and in feces (about 30%).
BioavailabilityDomperidone: about 15% due to first-pass metabolism; Ranitidine: about 50%.
Onset of ActionDomperidone: within 30-60 minutes; Ranitidine: within 1 hour.
Peak Plasma TimeDomperidone: 0.5-1 hour; Ranitidine: 1-3 hours.
Duration of ActionDomperidone: 4-6 hours; Ranitidine: 8-12 hours.

How It Works

This medicine combines two active ingredients with complementary actions. Domperidone blocks dopamine D2 receptors in the chemoreceptor trigger zone and in the gastrointestinal tract, which enhances gastric motility and reduces nausea. Ranitidine competitively blocks histamine H2 receptors on gastric parietal cells, leading to reduced basal and stimulated gastric acid secretion. The combination aims to improve symptoms of acid reflux and dyspepsia by both reducing acid and promoting forward movement of stomach contents.

Mechanism Steps

1
Domperidone blocks dopamine D2 receptors: Domperidone antagonizes dopamine D2 receptors in the chemoreceptor trigger zone and the gastrointestinal tract, which reduces nausea and enhances peristalsis.
2
Ranitidine blocks histamine H2 receptors: Ranitidine competitively inhibits histamine at H2 receptors on gastric parietal cells, decreasing cyclic AMP production and thus reducing gastric acid secretion.
3
Combined effect on gastric motility and acid reduction: The prokinetic action of domperidone moves stomach contents more efficiently into the small intestine, while ranitidine reduces the acidity of the stomach, leading to less reflux and irritation.

💡 How to Take combidom tablet

Dosage Information

Adult DosageThe usual adult dose is one tablet taken orally one to two times daily, preferably before meals. The exact dose and duration depend on the condition being treated and the patient's response. Dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function. Do not exceed the prescribed dose.
Pediatric DosagePediatric dosing is not established from available information. Consult a pediatrician.
Elderly DosageElderly patients may be more sensitive to the side effects of this medicine, especially cardiac arrhythmias and extrapyramidal symptoms. Dose adjustment may be necessary based on renal and hepatic function. Consult a doctor for appropriate dosing.
Renal ImpairmentIn patients with renal impairment, the ranitidine component may require dose reduction. For creatinine clearance less than 50 mL/min, a lower dose or longer dosing interval may be advised. Consult a doctor for individualized dosing.
Hepatic ImpairmentIn patients with hepatic impairment, domperidone metabolism may be reduced, increasing the risk of side effects. Dose reduction or avoidance may be necessary. Consult a doctor for individualized dosing.
Maximum Daily DoseThe maximum recommended daily dose is 2 tablets (domperidone 20 mg and ranitidine 300 mg) per day. Do not exceed this dose.
