Abstract
Infants and young children with severe acute malnutrition (SAM) are treated with empiric broad-spectrum antimicrobials. Parenteral ceftriaxone is currently a second-line agent for invasive infection. Oral metronidazole principally targets small intestinal bacterial overgrowth. Children with SAM may have altered drug absorption, distribution, metabolism and elimination. Population pharmacokinetics of ceftriaxone and metronidazole were studied, with the aim of recommending optimal dosing. Eighty-one patients with SAM (aged 2-45 months) provided 234 post-dose pharmacokinetic samples for total ceftriaxone, metronidazole and hydroxymetronidazole. Ceftriaxone protein binding was also measured in 190 of these samples. A 3-compartment model adequately described free ceftriaxone, with a Michaelis-Menten model for concentration and albumin dependent protein binding. A 1-compartment model was used for both metronidazole and hydroxymetronidazole, with only 1% of hydroxymetronidazole predicted to be formed during first-pass. Simulations showed 80 mg/kg once daily of ceftriaxone and 12.5 mg/kg twice daily of metronidazole were sufficient to reach therapeutic targets. This article is protected by copyright.
