The Annals of pharmacotherapy

To review the chemistry, pharmacology, microbiology, pharmacokinetics, pharmacodynamics, clinical efficacy, safety, dosage, and administration of bedaquiline, a novel oral diarylquinoline antimycobacterial agent approved by the Food and Drug Administration for the treatment of adults with pulmonary multidrug-resistant tuberculosis (MDR-TB). ⋯ In an era of emerging resistance and given the suboptimal efficacy and toxicity of currently available regimens for MDR-TB, bedaquiline represents a great addition to the existing armamentarium of anti-TB agents particularly in areas of the world where the disease is endemic.

Therapeutic hypothermia improves neurological recovery after witnessed cardiac arrest from ventricular fibrillation or tachycardia. Its application is expanding despite associated adverse events. ⋯ Adverse events of therapeutic hypothermia were numerous and frequent, necessitating monitoring. Neurological recovery is primarily driven by the type of arrest, the rapidity of ROSC, the time needed to provide and achieve therapeutic hypothermia, the development of seizures or infection, and the use of insulin or epinephrine.

Predisposition to adverse drug events with advancing age has led to the development of lists of potentially inappropriate medications (PIMs) to be avoided in the elderly, such as the Beers Criteria. The prevalence of Beers medications has been studied widely, but it is still unclear whether PIM use is predictive of adverse events in older people. ⋯ Due caution prescribing Beers medications in the elderly seems justified, paying particular attention to PIMs listed above and to the concurrent use of multiple PIMs. Our results also support the retention of specific medications on PIM lists in future developments.

Current guidelines recommend vancomycin trough concentrations 15 to 20 µg/mL in complicated infections and all trough concentrations above 10 µg/mL. ⋯ The divided-load vancomycin dosing strategy achieved measured trough concentrations 15 to 20 µg/mL for most critically ill patients within 24 hours of initial dosing, without allowing doses given during supratherapeutic concentrations.
