The American Geriatrics Society 2015 Beers Criteria Update Expert Panel has revised its recommendation to avoid use of nitrofurantoin in renal impairment from patients with a creatinine clearance (Clcr) of less than 60 mL/min to those with a Clcr of less than 30 mL/min, based on two retrospective studies that identified the safety and efficacy of nitrofurantoin in this population. This change in recommendation, along with increasing resistance to both sulfamethoxazole/trimethoprim and fluoroquinolones, gave rise to the advantages of nitrofurantoin and may reflect a surge in prescribing among the elderly. The purpose of the manuscript is to provide readers with a brief review of updated evidence to confidently treat older patients with nitrofurantoin.

Background And Objectives: Cefiderocol approved dosages are based on a prolonged infusion (PI) of 3 h that may not be adequate in all settings The objective of this study was to identify alternative cefiderocol dosage regimens based on short infusion (SI) or continuous infusion (CI).
Methods: We performed 1000-patient pharmacokinetic/pharmacodynamic (PK/PD) simulations based on a reference population model. Drug penetration into the epithelial lining fluid (ELF) was considered for pneumonia.

Polymyxin B is a viable option for treating antibiotic-resistant infections; however, current data on its pharmacokinetics, particularly in patients with renal insufficiency, remain inconclusive and necessitates further investigation. To address this gap, we conducted an open-label, single-center, single-dose, parallel-group pharmacokinetic study. Participants received an intravenous dose of 0.

Determining an effective dosing regimen for piperacillin-tazobactam in critically ill patients is challenging due to substantial pharmacokinetic variability caused by complex pathophysiological changes. To address this need, a prospective clinical study was conducted, which enrolled 112 critically ill patients and employed an opportunistic sampling strategy. Population modeling and simulation were performed to characterize the pharmacokinetics (PK) and probability of target attainment (PTA) of piperacillin-tazobactam under various dosing regimens.
