Ampicillin is a beta-lactam antibiotic effective in the treatment of Gram-positive bacteria. The AUC observed after administration of a single oral dose of 1000 mg ampicillin in a patient with normal kidney function was 40 mg-hr/L. What will be the difference if the same dose was administered to a patient with severe kidney failure if you know that the kidney is the main route of ampicillin elimination ?
