Esomeprazole Magnesium - Interactions and Warnings


The potential for interacting with other drugs is limited and is similar to that of omeprazole. The most common adverse effects are headache, respiratory infection, and abdominal symptoms. Esomeprazole has pharmacokinetic properties that may make it more effective than omeprazole in some patients.

Gastric polyps and nodules may be found in children receiving long-term omeprazole therapy.

Since intragastric pH will increase with esomeprazole treatment, it can be hypothesised that the absorption of digoxin and ketoconazole may be affected. In studies with diazepam, phenytoin and (R)-warfarin, it was shown that esomeprazole has the potential to interact with CYP2C19. Clarithromycin interacts with the metabolism of esomeprazole resulting in a doubling of the AUC of esomeprazole.

Caution is indicated when certain drugs are co-prescribed. The incidence of clinically significant drug interactions increases proportionately with the number of drugs taken and with the age of the patient. The drug interaction with the greatest clinical importance is the reduction in benzodiazepine clearance by omeprazole.
