Ranicom

Ranicom Uses, Dosage, Side Effects, Food Interaction and all others data.

Ranicom competitively blocks histamine at H2-receptors of the gastric parietal cells which inhibits gastric acid secretion. It does not affect pepsin secretion, pentagastrin-stimulated intrinsic factor secretion or serum gastrin.

Ranicom decreases the secretion of gastric acid stimulated by food and drugs. It also reduces the secretion of gastric acid in hypersecretory conditions such as Zollinger-Ellison syndrome. Marked improvements in the appearance of the esophageal tissues have been observed by endoscopic imaging after ranitidine therapy.

How Ranicom works

After a meal, the hormone gastrin, produced by cells in the lining of the stomach, stimulates the release of histamine, which then binds to histamine H2 receptors, leading to the secretion of gastric acid. Ranicom reduces the secretion of gastric acid by reversible binding to histamine (H2) receptors, which are found on gastric parietal cells. This process leads to the inhibition of histamine binding to this receptor, causing the reduction of gastric acid secretion. The relief of gastric-acid related symptoms can occur as soon as 60 minutes after administration of a single dose, and the effects can last from 4-10 hours, providing fast and effective symptomatic relief.

Dosage

Ranicom dosage

Ranicom Tablet & Syrup:

Duodenal and gastric ulcer: The usual dosage is 150 mg twice daily taken in the morning and evening or 300 mg as a single daily dose at night for 4 to 8 weeks.

Reflux oesophagitis: 150 mg twice daily or 300 mg at bed time for up to 8 weeks.

Episodic dyspepsia: 150 mg twice daily or 300 mg at bed time for up to 6 weeks.

Maintenance: 150 mg at night for preventing recurrences.

Child (peptic ulcer)

Ranicom IV injection & IV Infusion:

Ranicom injection may be given either as a slow (over a period of at least two minutes) intravenous injection of 50 mg, after dilution to a volume of 20 ml per 50 mg dose, which may be repeated every six to eight hours; or as an intermittent intravenous infusion at a rate of 25 mg per hour for two hours; the infusion may be repeated at six to eight hour intervals; or as an intramuscular injection of 50 mg (2 ml) every six to eight hours. In the prophylaxis of haemorrhage from stress ulceration in seriously ill patients or the prophylaxis of recurrent haemorrhage in patients bleeding from peptic ulceration, parenteral administration may be continued until oral feeding commences.: 2-4 mg/kg twice daily, maximum 300 mg daily.

In the prophylaxis of upper gastrointestinal haemorrhage from stress ulceration in seriously ill patient sapriming dose of 50 mg as low as intravenous injection followed by a continuous intravenous infusion of 0.125-0.250 mg/kg/hour may be preferred. In patients considered to be at risk of developing aspiration syndrome Ranicom injection 50 mg may be given intramuscularly or by slow intravenous injection 45 to 60 minutes before induction of general anaesthesia.

Children: The recommended oral dose for the treatment of peptic ulcer in children is 2 mg/kg to 4 mg/kg twice daily to a maximum of 300 mg ranitidine per day. Safety and effectiveness of Ranicom injection have not been established in case of children.

Reconstitutions

Slow IV inj: Ranicom 50 mg diluted to a concentration ≤2.5 mg/mL (e.g. total of 20 mL) with NaCl 0.9% inj or dextrose 5% or 10%, lactated Ringer's, Na bicarbonate 5% soln.

Intermittent slow IV infusion: Ranicom 50 mg diluted to a concentration ≤0.5 mg/mL (e.g. total of 100 mL) of dextrose 5% inj or NaCl 0.9%, lactated Ringer's, Na bicarbonate 5% soln.

Continuous IV infusion: Ranicom 150 mg diluted in 250 mL of dextrose 5% inj or NaCl 0.9%, lactated Ringer's, Na bicarbonate 5% soln.

Patients with Zollinger-Ellison syndrome or other hypersecretory conditions: Ranicom should be diluted to a concentration ≤2.5 mg/mL with dextrose 5% or NaCl 0.9%, lactated Ringer's, Na bicarbonate 5% soln.

Side Effects

Ranicom is well tolerated and side effects are usually uncommon. Altered bowel habit, dizziness, rash, tiredness, reversible confusional states, headache, decreased blood counts, muscle or joint pain have rarely been reported.

Toxicity

Oral doses of 1,000 mg/kg in mice and rats were not found to be lethal. Intravenous LD50 values in mice and rats were 77 and 83 mg/kg, respectively.

Overdose information

There has been limited experience with ranitidine overdose. Reported acute ingestions of up to 18 grams orally were followed by temporary adverse effects similar to the normal adverse effects of this drug, including tachycardia, bradycardia, dizziness, diarrhea, nausea, and vomiting, among other effects. Gait abnormalities and hypotension have also been observed. When an overdose with ranitidine is suspected, remove unabsorbed ranitidine from the gastrointestinal tract if possible, and monitor the patient and provide supportive therapy as required.

Precaution

Ranicom should be given in reduced dosage to patients with impaired renal and hepatic function.

Interaction

Delayed absorption and increased peak serum concentration with propantheline bromide. Ranicom minimally inhibits hepatic metabolism of coumarin anticoagulants, theophylline, diazepam and propanolol. May alter absorption of pH-dependent drugs (e.g. ketoconazole, midazolam, glipizide). May reduce bioavailability with antacids.

Food Interaction

  • Take with or without food. The absorption is unaffected by food.

Volume of Distribution

The volume of distribution is higher than body volume, and measures at approximately 1.4 L/kg. It concentrates in breast milk, but does not readily distribute into the cerebrospinal fluid.

Elimination Route

Ranicom is rapidly absorbed with peak concentrations reached within 1-3 hours after administration, and varying greatly among patients. Bioavailability is about 50%-60% due to hepatic metabolism. In a pharmacokinetic study of healthy males, the AUC 0-infinity was about 2,488.6 ng x h/mL and the median Tmax was 2.83 hours. Food or antacids have limited effects on absorption. One clinical study found that the administration of a potent antacid (150 mmol) in subjects in the fasted state led to decreased absorption of ranitidine.

Half Life

The elimination half-life or ranitidine is about 2.5-3 hours. It may be longer after oral administration versus injection. The plasma half-life is longer for elderly patients population due to a decrease in renal function, and is measured at 3-4 hours.

Clearance

Renal clearance is about 410 mL/min according to FDA prescribing information. Another resource mentions a plasma clearance of approximately 600 ml/min. Clearance is decreased in the elderly and those with impaired or hepatic renal function. It is recommended to decrease the dose of ranitidine by one-half in patients with renal impairment.

Elimination Route

This drug is mainly excreted in the urine but also excreted in the feces. About 30% of a single oral dose has been measured in the urine as unchanged drug within 24 hours of ingestion.

Pregnancy & Breastfeeding use

Pregnancy: Ranicom crosses the placenta. But there is no evidence of impaired fertility or harm to the foetus due to Ranicom. Like other drugs, Ranicom should only be used during pregnancy if considered essential.

Lactation: Ranicom is excreted in human breast milk. Caution should be exercised when the drug is administered to a nursing mother.

Contraindication

Patients hypersensitive to Ranicom

Special Warning

Use in elderly patients: In clinical trial the ulcer healing rates have been found similar in patients age 65 and over with those in younger patients. Additionally, there was no difference in the incidence of adverse effects.

Acute Overdose

Ranicom is very specific in action and accordingly no particular problems are expected following overdosage with the drug. Symptomatic and supportive therapy should be given as appropriate. If required, the drug may be removed from the plasma by haemodiaiysis.

Storage Condition

Store in a cool and dry place. protect from light.
