The antipyretic efficacy and safety of propacetamol compared with dexibuprofen in febrile children: a multicenter, randomized, double-blind, comparative, phase 3 clinical trial

摘要

We aimed to compare the antipyretic efficacy, safety, and tolerability between oral dexibuprofen and intravenous propacetamol in children with upper respiratory tract infection (URTI) presenting with fever. Patients aging from 6?months to 14?years admitted for URTI with axillary body temperature?≥?38.0?°C were enrolled and randomized into the study or control group. Patients in the study group were intravenously infused with propacetamol and subsequently oral placebo medication was administered. Patients in the control group were intravenously infused with 100?mL of 0.9% sodium chloride solution without propacetamol and then oral dexibuprofen was administered. We checked the body temperature of all patients at 0.5?h (hr), 1?h, 1.5?h, 2?h, 3?h, 4?h, and 6?h after oral placebo or dexibuprofen had been applied. A total of 263 patients (125 in the study group) were finally enrolled. The body temperatures of patients in the study group were significantly lower until 2?h after administration (37.73?±?0.58 vs 38.36?±?0.69?°C (p??0.001), 37.37?±?0.53 vs 37.88?±?0.69?°C (p??0.001), 37.27?±?0.60 vs 37.62?±?0.66?°C (p??0.001), 37.25?±?0.62 vs 37.40?±?0.60?°C (p?=?0.0452), at 0.5?h, 1?h, 1.5?h, and 2?h, respectively). The two groups showed no significant differences in terms of the range of body temperature decrease, the Area Under the Curve of body temperature change for antipyretic administration-and-time relationship, the maximum value of body temperature decrease during the 6?h test period, the number of patients whose body temperature normalized (?37.0?°C), the mean time when first normalization of body temperature, and the development of adverse events including gastrointestinal problem, elevated liver enzyme, and thrombocytopenia. Intravenous propacetamol may be a safe and effective choice for pediatric URTI patients presenting with fever who are not able to take oral medications or need faster fever control. CRIS KCT0002888 .
