- Ampicillin Esters + Lansoprazole— Lansoprazole may interfere with absorption of ampicillin esters where gastric pH is important for bioavailability.
- Ampicillin Esters + Omeprazole— Omeprazole may interfere with ampicillin esters absorption as gastric pH affects its bioavailability.
- Ampicillin Esters + Omeprazole And Sodium Bicarbonate— Omeprazole and sodium bicarbonate may interfere with ampicillin ester bioavailability through effects on gastric pH.
- Ampicillin Esters + Pantoprazole— Pantoprazole may decrease ampicillin esters absorption due to increased gastric pH.
- Ampicillin Esters + Pantoprazole Sodium— Pantoprazole can reduce ampicillin ester absorption by decreasing intragastric acidity, where gastric pH is important fo…
