Physiologically based pharmacokinetic-guided evaluation of dosing regimens of meropenem for the treatment of urinary tract infections in elderly and renally impaired patients

Introduction Upper urinary tract infections (UTI) are associated with critical illness and significant mortality. Meropenem is efficacious in treating UTI and has a systemic and urinary minimum inhibitory concentrations (MIC) breakpoint of 1 mg/L for Enterobacterales and 2 mg/L for Pseudomonas aeruginosa. As the fraction of meropenem excreted in the urine decreases with declining renal function, we applied […]
