Interactions

Amoxicillin: May reduce the efficacy of OC. May increase the effect of anticoagulants. Increased risk of allergic reactions w/ allopurinol. Increased and prolonged blood levels w/ probenecid. Chloramphenicol, macrolides, sulfonamides and tetracyclines may interfere w/ the bactericidal effect of amoxicillin. Clarithromycin: Serious adverse reactions have been reported in patients taking Clarithromycin concomitantly with CYP3A4 substrates. These include colchicine toxicity with colchicine; rhabdomyolysis with simvastatin, lovastatin, and atorvastatin; and hypotension and acute kidney injury with calcium channel blockers metabolized by CYP3A4 (e.g., verapamil, amlodipine, diltiazem, nifedipine). Most reports of acute kidney injury with calcium channel blockers metabolized by CYP3A4 involved elderly patients 65 years of age or older. Rabeprazole: May decrease serum concentration of ketoconazole, itraconazole and clopidogrel. Increased risk of hypomagnesaemia w/ diuretics and digoxin. May increase prothrombin time and INR of warfarin. May increase plasma concentration of saquinavir and methotrexate. Decreased serum levels w/ sucralfate. Potentially Fatal: May decrease plasma concentrations and pharmacological effects of rilpivirine and atazanavir.

Mechanism of Action

Amoxicillin: Inhibits bacterial cell wall synthesis by binding to one or more penicillin binding proteins that in turn inhibit the final transpeptidation step of peptoglycan synthesis in cell wall biosynthesis. Clarithromycin: Inhibits protein synthesis by binding to 50S ribosomal subunit causing antibacterial activity. Rabeprazole: Proton pump inhibitor (PPI); binds to H+/K+-exchanging ATPase (proton pump) in gastric parietal cells, blocking acid secretion.
