Effect of Fever on Antibiotic Pharmacokinetics The physiologic effects of fever could potentially alter PK of a drug although this is not well studied 92.
The reasons for this are likely related to confounders in the febrile model. For example, most febrile models use sepsis or endotoxemia to stimulate the febrile response 93—96.
One PK parameter that is likely affected at higher body temperatures is protein binding, which has been shown to be reduced at higher temperatures 97.
Thus, fever could potentially increase the free fraction of drug, which could enhance distribution and microbiologic activity, although could also hasten metabolism and excretion.And we are dedicated to being the best possible partner for our customers-helping to identify new opportunities to bring the future to life. In 1 case, a 44-year-old female of seizures and drug administration suggests to isolate and identify organisms causing infection and to determine their susceptibility.
Outside of protein binding, the effects of fever on drug PK are largely unknown in animal models due to difficulty in the ability to dissociate fever from other confounders induced in the febrile state.
Recognition of these differences is important; however, the clinical applicability of using age-related PK in an animal model and correlating it to age-related PK in a human is limited.
The main reason for this is the need to prove age-related changes in the animal model mimic those noted in humans. Without a study in neonatal humans, it is unknown whether these differences are applicable from the animal model.
When differences do occur in the animal model, it can provide the stimulus to study the PK in the age groups the antibiotic is being developed for in humans. However, when age-related differences do not occur in the animal model, it does not necessarily indicate that there are no significant clinical differences in drug PK in different aged humans.
With this caveat aside, there are examples of age-related changes in antimicrobial PK in animal models 99,100.
Oftentimes, these less common factors are investigated in animal models only after significant differences in PK are noted in different populations of humans.
A variety of questions can be addressed in these preclinical models to help direct clinical dosing regimens as well as address clinical problems such as toxicity or drug resistance.
The principal analysis tool in most of these studies is PD. There are too numerous to cite examples of how informative and predictive PD animal studies can be. The reader is directed to the many insightful reviews cited here,,81 for further information.
