Pharmacokinetics of potassium clavulanate in combination with amoxicillin in pediatric patients

Abstract
Two dosages of a liquid suspension formulation of amoxicillin and potassium clavulanate were tested in 34 infants and children. The smaller dosage resulted in suboptimal plasma concentrations. With a greater dosage (3.3 mg of clavulanate per kg and 13.3 mg of amoxicillin per kg), the mean peak plasma concentrations were 1.6 micrograms clavulanic acid per ml and 4.9 micrograms amoxicillin per ml.
