Part Descriptions
LP206568-0 Floxacillin.free
Floxacillin or flucloxacillin (tradename Flopen or Floxapen) is an isoxazolyl penicillin often used to treat many infections caused by Gram-positive species, such as streptococci and penicillinase-producing staphylococci, including methicillin-susceptible Staphylococcus aureus (MSSA). Studies have shown that flucloxacillin is 95%-97% bound to plasma albumin. The extent of binding to plasma proteins is important, as it is the unbound (free) fraction of drug that produces the pharmacological effect. For critically ill patients, hypoalbuminaemia may be observed, and the effects of hypoalbuminaemia on the pharmacokinetics of highly bound antiboitics may pose a potential risk for inappropriate antibiotic therapy in these patients.

LP207910-3 free DRUG/TOX
The measurement of free (unbound) drug concentrations in plasma is important for certain drugs and has two advantages over measurement of total concentration: (1) the free concentration is independent of changes in plasma binding (e.g., due to changes in albumin), and (2) the free concentration is more directly related to both the efficacy and toxicity of the drug PMID: 6636249. For most drugs and the majority of patients, measuring the free and total concentrations is not necessary. However, for certain drugs, including some anticonvulsants and antibiotics, and specific patient populations, such as critically ill or immunosuppressed patients, the free concentration is a better indicator of therapeutic effect and potential toxicity.
