Ketoprofen versus Paracetamol (Acetaminophen) or Ibuprofen in the Management of Fever

Abstract

Background: Fever is a common symptom in children and one of the major concerns of parents of younger and preschool-age children. Objective: To compare the efficacy and safety of ketoprofen with that of paracetamol (acetaminophen) and ibuprofen in the treatment of febrile conditions in children. Methods: Two prospective, randomized, double-blind, double-dummy, repeated-dose, multicentre, phase III studies with two parallel groups in each study were conducted in primary-care outpatient clinics. Children aged 6 months to 6 years presenting with a febrile condition and an oral body temperature of >38.8°C or rectal temperature of ≥39°C were eligible for inclusion. Patients were randomized to receive either ketoprofen syrup 0.5mg/kg, ibuprofen suspension 5 mg/kg or paracetamol suspension 15 mg/kg every 6 hours by the oral route. The primary outcome measure was the change in temperature at 3 hours (H3), compared with baseline (H0). Results: All three treatments provided similar mean maximum decreases of 1.4–1.5°C in body temperature at H3 compared with H0. Use of ketoprofen was not associated with any increased risk of adverse events compared with the two reference compounds. Conclusion: Ketoprofen 0.5 mg/kg appeared to be equivalent to the standard antipyretic doses of the reference products ibuprofen 5 mg/kg and paracetamol 15 mg/kg. Ketoprofen at the 0.5 mg/kg dose should be an effective and safe option for symptomatic management of fever in children.
