Drug Interactions between bacampicillin and Prepopik

GENERALLY AVOID: Coadministration with antacids, H2-receptor antagonists, proton pump inhibitors, or other agents with acid neutralizing or reducing effects may decrease the oral bioavailability and plasma concentrations of ampicillin from bacampicillin. The exact mechanism of interaction is unknown but may be related to degradation of the prodrug when gastric pH is increased.

MANAGEMENT: The possibility of a reduced or subtherapeutic response to bacampicillin should be considered during coadministration with antacids, H2-receptor antagonists, proton pump inhibitors, or other agents that can increase gastric pH. Preferably, these agents should be avoided during therapy with bacampicillin, or an alternative antibiotic be prescribed if these medications cannot be discontinued. Patients treated with antacids (or oral medications that contain antacids such as didanosine buffered tablets or pediatric oral solution) may minimize the effects of the interaction with bacampicillin by separating the times of administration by at least 2 hours.

GENERALLY AVOID: Theoretically, use of sodium picosulfate during or following antibiotic treatment may result in a reduced laxative effect of sodium picosulfate. The proposed mechanism involves antibiotic-induced reduction of colonic bacteria that hydrolyze sodium picosulfate, a prodrug, to its active metabolite bis-(p-hydroxyphenyl)-pyridyl-2-methane (BHPM), a compound that stimulates colonic peristalsis. The clinical significance of this effect remains unknown.

MANAGEMENT: Consider use of an alternate laxative in patients who have recently taken or are currently taking an antibiotic. If concomitant use is required, additional bowel cleansing and colonoscopy may be required.
