Y1 - 2021 N1 - T2 - Katzung & Trevor's Pharmacology: Examination & Board Review, 13e AB - In the antimicrobial treatment of infections, multiple daily dosage regimens traditionally have been designed to maintain serum concentrations above the minimal inhibitory concentration (MIC) for as long as possible. However, the in vivo effectiveness of some antibiotics, including aminoglycosides, results from concentration-dependent killing. As the plasma level increases above the MIC, aminoglycosides kill an increasing proportion of bacteria and at an increasingly rapid rate. Many other antibiotics, including penicillins and cephalosporins, cause time-dependent killing of microorganisms: their in vivo efficacy is directly related to time above MIC and is independent of concentration once the MIC has been reached.
