A Pooled Population Pharmacokinetic Study of Oral and Intravenous Administration of Clavulanic Acid in Neonates and Infants: Targeting Effective Beta‐Lactamase Inhibition

Data published on the oral clavulanic acid pharmacokinetics in the pediatric population is lacking. This research aimed to describe clavulanic acid disposition following oral and intravenous administration and to provide insights into clavulanic acid exposure based on threshold concentrations for (pre-)term neonates and infants. This pooled population pharmacokinetic study combined four datasets for analysis in NONMEM v7.4.3. Clavulanic acid exposure was simulated using the percentage of time above the threshold concentrations (%fT > C
