WebThe medical literature is replete with articles in which there is confusion between "free concentration" and "unbound fraction" (f u ), which is the ratio of free to total plasma concentration. ... This erroneous approach, of using free antimicrobial drug fraction, is not limited to the derivation of PK/PD cutoff, but may also have consequences ... WebBacteriostatic effects are typically observed when the free drug concentration exceeds the MIC for 35-40% of the dosing interval for cephalosporins, 30% for penicillins and 20% for carbapenems. To achieve maximal bactericidal affect, the drug concentration has to be above the MIC 60-70% of the dosing interval for cephalosporins, 50% for ...
