Compositions and methods for increasing the oral absorption of antimicrobials

摘要

The present invention provides compositions and methods for increasing absorption of antibacterial agents, particularly third generation cephalosporin antibacterial agents, in oral dosage solid and/or suspension forms. Specifically, the composition is comprised of a biopolymer that is preferably swellable and/or mucoadhesive, a antimicrobial agent, and a cationic binding agent contained within the biopolymer such that the binding agent is tonically bound or complexed to at least one member selected from the group consisting of the biopolymer and the antimicrobial agent.
