Objective: Our purpose was to study the pharmacokinetics of ceftazidime at different stages of pregnancy and in the nonpregnant state to determine whether glomerular filtration rate is altered and whether tubular secretions occurs.
Study Design: Twelve pregnant women with asymptomatic bacteruria were given a bolus dose of 400 mg of ceftazidime followed by a constant infusion for 4 hours. Inulin was infused simultaneously to determine glomerular filtration rate.
