Pharmacokinetics of antibiotics in burn patients.
Drug pharmacokinetics are significantly altered in the burned patient but the interplay of a large number of variables is involved in deciding how an individual will deal with a drug. Consequently the burn patient population shows significant inter- and intrapatient variation. In 1976 altered aminoglycoside pharmacokinetics and the need for increased dosage in burn patients was reported but, despite this early study, a review of the currently available literature shows that for many drugs there is a paucity of information to support current dosage recommendations. In addition, many reports are based upon small numbers of patients, and even in larger studies there is no standardization of the study population with regard to the important variables known to affect drug handling. For the sub-population of burn patients who eliminate drugs extremely rapidly, a concern exists over the adequacy of antibiotic dosing. It is suggested that antibiotic serum concentrations be measured for all drugs in every patient to ascertain whether there is a significant problem with dosing. Additionally, future pharmacokinetic studies need to be standardized in burn patients.
