Abstract
Ceftolozane-tazobactam, a combination of the novel antipseudomonal cephalosporin ceftolozane and the well-established extended-spectrum β-lactamase inhibitor tazobactam, is approved for treating complicated urinary tract infections (cUTI) and complicated intra-abdominal infections (cIAI) in adults. To determine doses likely to be safe and efficacious in phase 2 pediatric trials for the same indications, single-dose ceftolozane-tazobactam plasma pharmacokinetic data from a recently completed phase 1 trial in pediatric patients (birth to 2 only): for children ≥12 years old, 1.5 g ceftolozane-tazobactam (1 g ceftolozane with 0.5 g tazobactam), and for neonates/very young infants, infants, and children <12 years old, 20/10 mg/kg of body weight ceftolozane-tazobactam, both via a 1-h intravenous infusion every 8 h.Keywords
