Major Heartburn Relief Maximum Strength
Major Heartburn Relief Maximum Strength Uses, Dosage, Side Effects, Food Interaction and all others data.
Major Heartburn Relief Maximum Strength is a histamine H2-receptor antagonist. Major Heartburn Relief Maximum Strength completely inhibits the action of histamine on H2-receptors of parietal cell. It inhibits basal, overnight and pentagastrin stimulated gastric acid secretion. The H2-receptor antagonist activity of Major Heartburn Relief Maximum Strength is slowly reversible, since the drug dissociates slowly from H2-receptor.
Major Heartburn Relief Maximum Strength decreases the production of gastric acid, suppresses acid concentration and pepsin content, and decreases the volume of gastric secretion. Major Heartburn Relief Maximum Strength inhibits both basal and nocturnal gastric acid secretion, as well as acid secretion stimulated by food, caffeine, insulin, and pentagastrin.
Major Heartburn Relief Maximum Strength has a dose-dependent therapeutic action, with the highest dose having the most extended duration of action and the highest inhibitory effect on gastric acid secretion. Following oral administration, the onset of action is within one hour, and the peak effect is reached within 1-3 hours. The duration of effect is about 10-12 hours.

Uses
Major Heartburn Relief Maximum Strength is used for-
- Short term treatment of active duodenal ulcer and benign gastric ulcer
- Maintenance therapy for prevention of relapses of duodenal ulceration
- Gastro-oesophageal reflux disease
- Zollinger Ellison Syndrome
Major Heartburn Relief Maximum Strength is also used to associated treatment for these conditions: Chronic Back Pain, Duodenal Ulcer, Erosive Esophagitis, Extra-Articular Rheumatism, Gastritis, Heartburn, Helicobacter Pylori Infection, Multiple Endocrine Neoplasia, Muscle Spasms, Nonspecific Pain Post Traumatic Injury, Osteoarthritis (OA), Postoperative pain, Stress Ulcers, Zollinger-Ellison Syndrome, Active Gastric ulcer, Acute Duodenal Ulcers, Gastrointestinal ulceration, Pathological hypersecretory conditions, Symptomatic non-erosive gastroesphageal reflux disease
How Major Heartburn Relief Maximum Strength works
Histamine acts as a local hormone that stimulates the acid output by parietal cells via a paracrine mechanism. Neuroendocrine cells called enterochromaffin-like (ECL) cells lie close to the parietal cells and regulate the basal secretion of histamine. Histamine release is also promoted from stimulation by acetylcholine and gastrin, a peptide hormone. Gastrin (G) cells release gastrin, which works on CCK2 receptors on ECL cells. This action promotes the release of histamine from ECL cells. Upon release, histamine acts on H2 receptors expressed on the basolateral membrane of parietal cells, leading to increased intracellular cAMP levels and activated proton pumps on parietal cells. Proton pump releases more protons into the stomach, thereby increasing the secretion of acid. In conditions that are associated with acid hypersecretion such as ulcers, there is a loss of regulation of acid secretion. Major Heartburn Relief Maximum Strength works on H2 receptors and blocks the actions of histamine.
Dosage
Major Heartburn Relief Maximum Strength dosage
Duodenal ulcer: 40 mg at night for 4 to 8 weeks
Benign gastric ulcer: 40 mg at night for 4 to 8 weeks; Maintenance therapy: 20 mg at night for preventing the recurrences of duodenal ulceration
Gastro-oesophageal reflux disease: 20 mg twice daily for 6 to 12 weeks
Zollinger Ellison syndrome: The recommended starting dose is 20 mg every six hours. Dosage should then be adjusted to individual response. Doses up to 160 mg every six hours have been administered to some patients without the development of significant adverse effects.
Dosage can be administered irrespective of meals. Antacids may be given concomitantly if needed.
Side Effects
Major Heartburn Relief Maximum Strength is generally well tolerated and side effects are uncommon. Dizziness, headache, constipation and diarrhoea have been reported rarely. Other side effects reported less frequently include dry mouth, nausea and/or vomiting, rash, abdominal discomfort, anorexia and fatigue.
Toxicity
The oral LD50 is 4049 mg/kg in rats and 4686 mg/kg in mice. The subcutaneous LD50 is 800 mg/kg in rats and mice. The lowest published toxic dose (TDLo) in man following oral administration is 4 mg/kg/7D.
Symptoms of overdose resemble the adverse events seen with the use of recommended doses, and they should be responded with supportive and symptomatic treatment. Any unabsorbed drug should be removed from the gastrointestinal tract, and the patient should be monitored accordingly. The use of hemodialysis to eliminate the drug from the systemic circulation is effective, but the experience of using hemodialysis in response to famotidine overdose is limited in clinical settings.
Precaution
Dosage reduction should be considered or interval between doses should be prolonged if creatinine clearance falls to or below 30 ml/min.
Interaction
Major Heartburn Relief Maximum Strength does not interact with the cytochrome P450 linked drug metabolising enzyme system. So, no interactions have been found in man with Warfarin, Theophylline, Phenytoin, Diazepam, Propranolol, Aminopyrine or antipyrine.
Food Interaction
- Avoid excessive or chronic alcohol consumption. Alcohol increases the risk of gastric irritation.
- Limit caffeine intake. Caffeine and other acidic beverages increases the risk of gastric irritation.
- Take with or without food. Food slightly increases bioavailability, but not to a clinically significant extent.

Major Heartburn Relief Maximum Strength Disease Interaction
Volume of Distribution
The steady-state volume of distribution ranges from 1.0 to 1.3 L/kg. Major Heartburn Relief Maximum Strength is found in breast milk; however, it is found in breast milk at the lowest concentrations compared to other H2 receptor antagonists.
Elimination Route
Following oral administration, the absorption of famotidine is dose-dependent and incomplete. The oral bioavailability ranges from 40-50%, and the Cmax is reached in 1-4 hours post-dosing. While the bioavailability can be slightly increased with the intake of food and decreased by antacids, there is no clinical significance.
Half Life
The elimination half-life is about 2 to 4 hours. The half-life is expected to increase nonlinearly in patients with decreased renal function.
Clearance
Renal clearance is 250-450 mL/min, indicating some tubular excretion. Because the renal clearance rate exceeds the glomerular filtration rate, famotidine is thought to be mainly eliminated via both glomerular filtration and renal tubular secretion.
Elimination Route
About 65-70% of the total administered dose of famotidine undergoes renal elimination, and 30-35% of the dose is cleared by metabolism. Following intravenous administration, about 70% of the drug is eliminated in the urine as an unchanged drug.
Pregnancy & Breastfeeding use
Pregnancy: There are no adequate, well controlled studies on Major Heartburn Relief Maximum Strength in pregnancy, but it is known to cross the placenta and should be prescribed only if clearly needed.
Lactation: It is not known whether Major Heartburn Relief Maximum Strength is secreted into human milk, nursing mothers should either stop nursing or stop taking the drug.
Contraindication
There are no known contraindication to Major Heartburn Relief Maximum Strength. If any evidence of hypersensitivity appear, the therapy should be discontinued and consultation with physician is required.
