Objective: The aim of the study is to compare the efficacy and tolerability of a single dose of Children’s Motrin® Suspension Liquid or Suspension Drop Vs Dipyrone Injectable used as antipyretics in febrile children.

Methods: This was a double blind, single dose, multi-center, parallel, randomized study. All eligible subjects were randomized to Dipyrone or Ibuprofen treated group.  The dosage ranged from 6.3~9.4mg/kg for each group. For efficacy analysis, the onset of action, the duration of action, the difference of temperature from baseline, the analgesic effect and the investigator’s overall impression of each treatment were analyzed. For tolerability evaluation, all adverse experience during the 8 hours period of study was analyzed. All statistical tests were two-sided at significance level of 0.05.

Results: The demographic data of the Motrin group and the Dipyrone group were comparable. As comparing the efficacy data, the overall antipyretic effect of Motrin group was 99.3% which was superior to 88.6% of Dipyrone group, p<0.05. The result showed that time at onset of antipyretic effect, which was defined as the earliest time that the temperature was³1.0 degree centigrade below baseline, is earlier in Motrin group(1.16±0.10h) than in Dipyrone group(1.68±0.15h), p<0.05. In Motrin group duration of antipyretic effect was almost up to 8 hours which was longer than in Dipyrone group, p<0.05. The maximum temperature decline (2.30±0.65°C) was larger in Motrin group than in Dipyrone group(1.85±0.82°C), p<0.05. Accordingly, the maximum percentage of decline was larger in Motrin group(88.3±26.3%) than in Dipyrone group(69.7±30.2%), p<0.05. The overall appraisal by investigator was significantly better in Motrin group than that in Dipyrone group, p<0.05. Each group had good effect on pain relief after medication, p<0.05. No adverse experience occurred.

Conclusions:  Children’s Motrin® suspension liquid and drop were highly effective and safe for children’s fever, which in turn became the better choice in the clinical practice in pediatric emergency unit.
