🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionThis medicine is given by injection, so absorption is not required. It is completely available to the body after intravenous administration.
DistributionRanitidine distributes widely into body tissues and fluids, including breast milk. It crosses the placenta. The volume of distribution is approximately 1.4 L/kg.
Protein BindingApproximately 15% of ranitidine is bound to plasma proteins.
MetabolismRanitidine undergoes limited hepatic metabolism. The main metabolites are N-oxide, S-oxide, and desmethyl ranitidine, which are pharmacologically less active than the parent drug.
Half-LifeThe elimination half-life of ranitidine is approximately 2 to 3 hours in healthy adults. It is prolonged in patients with kidney impairment.
ExcretionRanitidine is primarily excreted unchanged in the urine. About 30% of an intravenous dose is recovered in urine as unchanged drug, and the rest is excreted as metabolites. Renal clearance is the major route of elimination.
BioavailabilityBioavailability is 100% after intravenous administration. After intramuscular injection, bioavailability is approximately 90% to 100%.
Onset of ActionAcid suppression begins within 30 to 60 minutes after intravenous administration.
Peak Plasma TimePeak plasma concentration is reached at the end of an intravenous infusion or within 15 minutes after intramuscular injection.
Duration of ActionA single dose suppresses gastric acid for approximately 4 to 8 hours.

How It Works

This medicine works by competitively blocking histamine H2 receptors located on the basolateral membrane of gastric parietal cells. This blockade reduces cyclic AMP production inside the parietal cell, which in turn decreases the activity of the proton pump and lowers both basal and stimulated gastric acid secretion. It also reduces pepsin output and increases gastric pH.

Mechanism Steps

1
Binding to H2 receptors: This medicine binds competitively to histamine H2 receptors on the surface of gastric parietal cells.
2
Reduction of cyclic AMP: Blocking the H2 receptor reduces the production of cyclic AMP inside the parietal cell.
3
Decreased proton pump activity: Lower cyclic AMP levels lead to reduced activity of the hydrogen-potassium ATPase pump, which is responsible for secreting acid into the stomach.
4
Reduced gastric acid secretion: As a result, both the volume and concentration of gastric acid decrease, and gastric pH rises.

💡 How to Take Rancafe Injection

Strength: Injection, 2 ml vial containing ranitidine 50 mg (25 mg/mL).

1This medicine is given by a healthcare professional only.
2It is administered as an intravenous or intramuscular injection.

Dosage Information

Adult DosageThe usual adult dose of this medicine is 50 mg given by intravenous or intramuscular injection every 6 to 8 hours. For continuous intravenous infusion, a dose of 150 mg may be infused over 24 hours. For aspiration prophylaxis before surgery, 50 mg is often given 45 to 60 minutes before anesthesia. Dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function.
Pediatric DosagePediatric dosing is not established from available information. Consult a pediatrician.
Elderly DosageElderly patients may require a lower dose because kidney function often declines with age. Dose must be individualized by a qualified clinician based on renal function and clinical response.
Renal ImpairmentIn patients with kidney impairment, the dose of this medicine should be reduced. For creatinine clearance less than 50 mL/min, the usual dose is 50 mg every 12 to 24 hours. Dose must be individualized by a qualified clinician based on renal function.
Hepatic ImpairmentIn patients with severe liver disease, the dose may need to be reduced. Monitor for side effects. Dose must be individualized by a qualified clinician.
Maximum Daily DoseThe maximum recommended daily dose is 400 mg per day by injection, but this may vary based on indication and patient factors. Dose must be individualized by a qualified clinician.
