Axcel Cimetidine
Axcel Cimetidine Uses, Dosage, Side Effects, Food Interaction and all others data.
Axcel Cimetidine competitively inhibits histamine at H2-receptors of the gastric parietal cells resulting in decreased gastric acid secretion, gastric volume and hydrogen ion concentration. It is also used in patients with pancreatic insufficiency to reduce the breakdown of pancreatic enzyme supplements.
Axcel Cimetidine is a histamine H2-receptor antagonist. It reduces basal and nocturnal gastric acid secretion and a reduction in gastric volume, acidity, and amount of gastric acid released in response to stimuli including food, caffeine, insulin, betazole, or pentagastrin. It is used to treat gastrointestinal disorders such as gastric or duodenal ulcer, gastroesophageal reflux disease, and pathological hypersecretory conditions. Axcel Cimetidine inhibits many of the isoenzymes of the hepatic CYP450 enzyme system. Other actions of Axcel Cimetidine include an increase in gastric bacterial flora such as nitrate-reducing organisms.

How Axcel Cimetidine works
Axcel Cimetidine binds to an H2-receptor located on the basolateral membrane of the gastric parietal cell, blocking histamine effects. This competitive inhibition results in reduced gastric acid secretion and a reduction in gastric volume and acidity.
Dosage
Axcel Cimetidine dosage
Benign gastric and duodenal ulceration: 800 mg daily at bedtime or 400 mg bid for at least 4 wk (duodenal ulcer), 6 wk (gastric ulcer) and 8 wk (NSAID-associated ulcer). Maintenance: 400 mg daily at bedtime or bid.
GERD: 400 mg 4 times/day or 800 mg bid for 4-12 wk.
Zollinger-Ellison syndrome: 300 or 400 mg 4 times/day.
Prophylaxis of GI haemorrhage from stress ulceration: 200-400 mg 4-6 hrly.
Prophylaxis of acid aspiration during general anaesth: 400 mg 90-120 min before induction of anaesth up to 400 mg 4 hrly if needed.
Non-ulcer dyspepsia: Max: 800 mg/day in divided doses.
Prophylaxis of nocturnal heartburn: 100 mg at bedtime.
Short bowel syndrome: Initial: 400 mg bid, adjusted according to response.
Pancreatic insufficiency: 800-1600 mg/day in 4 divided doses. IV
Benign gastric and duodenal ulceration; Zollinger-Ellison syndrome Intermittent infusion: 300 mg 6-8 hrly infused over 15-20 min. Max: 2400 mg/day.
Continuous infusion: 37.5 mg/hr (900 mg/day). A 150 mg IV loading dose may be given in patients requiring rapid elevation of gastric pH.
Should be taken with food.
Side Effects
Diarrhoea, other GI disturbances, dizziness, headache, tiredness, myalgia, arthralgia, rashes, altered LFTs, reversible confusional states. Rarely, hypersensitivity reactions and fever, reversible alopecia, blood disorders (e.g. agranulocytosis, leucopenia, and thrombocytopenia), acute pancreatitis, interstitial nephritis, hallucinations and depression, CV disorders (e.g. bradycardia, tachycardia, heart block), transient hypotension, gynaecomastia and impotence.
Toxicity
In the rare event of cimetidine overdose, it is vital to maintain the airway and cardiovascular status. The patient should be closely monitored and provided with symptomatic and supportive treatment as needed. Interventions such as gastric lavage and administration of activated charcoal may be initiated if deemed appropriate and necessary.
Precaution
History of peptic ulcer. Increased risk of developing community-acquired pneumonia in the elderly, patients with chronic lung disease, DM, or the immunocompromised. Increased possibility of a hyperinfection caused by Strongyloides stercoralis in immunocompromised patients. Possibility of malignancy should be excluded prior to therapy as the drug may mask symptoms and delay diagnosis of gastric malignancy. Avoid rapid IV inj. Renal and hepatic impairment. Pregnancy and lactation.
Interaction
Reduces absorption of dasatinib, ketoconazole, itraconazole and posaconazole. May increase serum levels of phenytoin, theophylline, lidocaine, hydroxyzine and oral anticoagulants. Absorption may be reduced by antacids. Decreased bioavailability with metoclopramide, sucralfate or propantheline. May potentiate the myelosuppressive effects (e.g. agranulocytosis, neutropenia) of myelosuppressive drugs (e.g. antimetabolites, alkylating agents) or therapies (e.g. radiation).
Food Interaction
- Take with food. Food increases bioavailability. For prophylaxis of gastric symptoms, take cimetidine 30-60 minutes prior to food administration.
Axcel Cimetidine Alcohol interaction
[Minor] Concurrent use of cimetidine and ethanol may result in increased ethanol concentrations.
The mechanism appears to be due to inhibition of gastric alcohol dehydrogenase by cimetidine, leading to increased bioavailability of the alcohol and inhibition of hepatic metabolism of alcohol.
The clinical significance of this interaction is limited.
More importantly, patients requiring cimetidine for gastrointestinal disease should be counseled to avoid alcohol to prevent worsening of their disease.
The other H-2 receptor antagonists appear to have minimal effects on the concentrations of alcohol.
Axcel Cimetidine Drug Interaction
Moderate: duloxetine, duloxetineMinor: acetaminophen, acetaminophen, cyanocobalamin, cyanocobalamin, cholecalciferol, cholecalciferolUnknown: aspirin, aspirin, diphenhydramine, diphenhydramine, omega-3 polyunsaturated fatty acids, omega-3 polyunsaturated fatty acids, pregabalin, pregabalin, ascorbic acid, ascorbic acid, cetirizine, cetirizine
Axcel Cimetidine Disease Interaction
Major: liver disease, GI bleedingModerate: hemodialysis, renal dysfunction
Volume of Distribution
The volume of distribution of cimetidine is reported to be 1 L/kg.
Elimination Route
Two peak plasma concentrations are often observed after oral administration of cimetidine, likely as a result of discontinuous absorption in the gastrointestinal tract. In healthy patients, the absolute bioavailability of cimetidine is approximately 60%; however, the bioavailability can be as high as 70% in patients with peptic ulcer disease. Overall, rates of bioavailability are much more variable in patients with peptic ulcer disease.
Half Life
Axcel Cimetidine's half-life is estimated to be around 2 hours.
Clearance
Axcel Cimetidine's reported systemic clearance value is approximately 500-600 ml/min.
Elimination Route
Axcel Cimetidine is excreted primarily in the urine.
Pregnancy & Breastfeeding use
Pregnancy Category B. Either animal-reproduction studies have not demonstrated a foetal risk but there are no controlled studies in pregnant women or animal-reproduction studies have shown an adverse effect (other than a decrease in fertility) that was not confirmed in controlled studies in women in the 1st trimester (and there is no evidence of a risk in later trimesters).
Contraindication
Axcel Cimetidine is contraindicated in any patient hypersensitive to the drug or its components.
Acute Overdose
Symptoms: Dizziness, bradycardia, CNS depression, vomiting.
Management: Induce vomiting and/or gastric lavage, followed by symptomatic and supportive treatment.
