For time-dependent antibiotics, such as beta-lactams and glycopeptides, optimal bacterial kill is achieved by maximising the time of the concen-tration over the MIC (T >MIC). The maximum effect is achieved in septic patients when this time is approaching 100% of the dosing interval. Area under curve/MIC. For area under curve …

Figure 14.21 The Etest can be used to determine the MIC of an antibiotic. In this Etest, vancomycin is shown to have a MIC of 1.5 μg/mL against Staphylococcus aureus. Check Your Understanding. In microbiology, the minimum inhibitory concentration (MIC) is the lowest concentration of a chemical, usually a drug, which prevents visible growth of a bacterium or bacteria. MIC depends on the microorganism, the affected human being (in vivo only), and the antibiotic itself. It is often expressed in micrograms per milliliter (μg/mL) or milligrams per liter (mg/L). The MIC is determined by preparing of the chemical in vitro at increasing concentrations, incubat…

However, the observed discrepancy (less than one twofold dilution), even for the most degraded drug for which the concentration at 24 h was reduced by two thirds, suggests that this would …
Webb20 juli 2024 · Time-dependent antibiotics exert optimal bactericidal effects when drug concentrations are maintained above the MIC for at least 40–50% of the dosing interval.
