The occurrence of early-onset RS in multiplex and/or consanguineous families suggests that genetic control of the host response to K. rhinoscleromatis may be involved in the pathogenesis of RS in endemic areas.
Therapeutic drug monitoring (TDM) is necessary for certain drugs to ensure that the levels are sufficient to be effective, but not so high as to cause adverse effects. This review summarizes the literature regarding TDM for newer-generation extended-spectrum triazoles, including when TDM may be necessary for each drug and why, and laboratory techniques used for the measurement of levels of these drugs. The document includes recommendations for the use of TDM for each triazole that is discussed.
Infants are therapeutic orphans. Many drugs used in infants are used “off-label”, increasing the risk of drug toxicity and suboptimal efficacy in this vulnerable population. This knowledge gap in clinical pharmacology is partly attributed to challenges associated with conducting clinical trials in infants. Consequently, there is a need for novel and efficient study designs more suited to this population. Available literature describing the use of minimal-risk approaches to characterize the pharmacokinetics (PK) of drugs in infants was critically reviewed. Population PK approach with sparse sampling was found to be well established. Other, more recent alternatives, like dried blood spots sampling, opportunistic design, and the use of non-blood matrices are promising strategies with an increasing number of applications in infants. Physiologically based pharmacokinetic modeling provides valuable insight in drug disposition but still needs more prospective validation. Increasing experience with these methods provides understanding of their strengths and limitations and will help improve the design of future PK studies in infants.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
