Lansoprazole + Amoxicillin + Clarithromycin


This is indicated for the eradication of H. pylori in active chronic gastric, duodenal and gastric ulcers.


Lansoprazole is a proton-pump inhibitor which inhibits the stomach's production of gastric acids. Amoxicillin is a penicillin antibiotic. It acts by inhibiting the synthesis of bacterial cell inhibits cross-linkage between the linear peptidoglycan polymer chains that make up a major component of the cell walls of both Gram-positive and Gram-negative bacteria. Clarithromycin is a macrolide antibiotic.It prevents bacteria from growing by interfering with their protein synthesis. It binds to the subunit 50S of the bacterial ribosome and thus inhibits the translation of peptides

Dosage & Administration

Adult dose: One strip twice daily for 7-14 days or as per the physician's advice.

Geriatric use: Elderly patients may suffer from asymptomatic renal and hepatic dysfunction. Care should be taken when administering to these patients.


  • Lansoprazole is metabolized through the cytochrome P450 system,specially through the CYP3A and CYP2C19 isozymes.Studies in healthy subjects have shown that Lansoprazole does not have clinically significant interactions with other drugs metabolized by the cytochrome P450 system, such as warfarin, antipyrine, indomethacin, ibuprofen, phenytoin, propranolol, prednisolone, diazepam, clarithromycin or terfenadine.
  • Clarithromycin use in patients who are receiving theophylline may be associated with increase of serum theophylline concentrations.
  • There have been reports of interactions of erythromycin and/or clarithromycin with carbamazepine, cyclosporine, tacrolimus, hexobarbital, phenytoin, alfetanil, disopyramide, lovastatin, bromocriptine, valproate, terfenadine, cisapride, pimozide & astemizole.


This is contraindicated in patients with known hypersensitivity to any of its component.

Side Effects

Adverse reactions which were reported as possibly or probably related to treatment (>3%) in clinical trials when all three components of this therapy were given concomitantly are listed below and divided by body systems. Digestive system: Nausea, vomiting, diarrhea, dark stools, dry mouth, glossitis, oral moniliasis, stomatitis, tongue discoloration. Musculoskeletal System: myalgia. Nervous System: confusion, headache, dizziness; Skin: skin reactions. Urogenital System: vaginitis,vaginal moniliasis.

Pregnancy & Lactation

There were no adequate and well-controlled studies  in pregnant women. This should be used during pregnancy only if the potential benefit justifies the potential risk of the mother. Amoxicillin is excreted in human milk in very small amounts. Because of the potential for serious adverse reactions in nursing infants. A decision should be made whether to discontinue nursing or to discontinue the drug therapy, taking into account the importance of the therapy to the mother.

Precautions & Warnings

Serious and occasionally fatal hypersensitivity (anaphylactoid) reactions have been reported in patients on Amoxicillin therapy. These reactions are more appropriate to occur in individuals with a history of penicillin hypersensitivity. Clarithromycin should not be used in pregnant women except in clinical circumstances where no alternative therapy is appropriate.
