A double-blind study of the efficacy and safety of multiple daily doses of amikacin versus one daily dose for children with perforated appendicitis in Costa Rica.

Background: There is evidence that aminoglycosides given in a single daily dose (once daily dose, ODD) are as effective and safe as multiple daily doses (MDD). However, the published pharmacokinetic and pharmacodynamic data are overly representative of pediatric populations in Europe and the USA, and not representative of low or middle-income countries such as Costa Rica, in which the patient population might differ from those in higher income settings.

Methods: A double-blind, randomized clinical trial of the efficacy and safety of ODD vs.
