The pharmacokinetics of antibiotics in patients with obesity – A systematic review and consensus guidelines for dose adjustments (2025) Anne-Grete Märtson

Description

This systematic review summarizes evidence on antibiotic pharmacokinetic alterations caused by obesity and provides guidance for dose adjustment in adult patients (BMI >30 kg/m²). The review found that obesity modestly alters the pharmacokinetics of β-lactam antibiotics (not supporting routine dose adjustments), but significantly impacts aminoglycosides and glycopeptides, for which weight-based dosing is recommended. Overall evidence certainty was low or very low.
