Insights
Ibuprofen is more effective than acetaminophen for reducing fever in children with infectious illnesses. This study found ibuprofen led to greater temperature reduction at 1, 2, and 4 hours, with similar safety profiles.
Area of Science:
- Pediatric pharmacology
- Infectious disease management
- Evidence-based medicine
Background:
- Fever is a common symptom in children with infectious diseases.
- Ibuprofen and acetaminophen are widely used antipyretics in pediatric populations.
- Comparative efficacy and safety data are crucial for clinical decision-making.
Purpose of the Study:
- To evaluate and compare the efficacy of ibuprofen versus acetaminophen in treating infectious fever in children.
- To assess temperature reduction at specific time points (1, 2, and 4 hours) post-administration.
- To analyze and compare the incidence of adverse events associated with each medication.
Main Methods:
- Systematic review and meta-analysis of randomized controlled trials and retrospective cohort studies.
- Inclusion criteria focused on studies comparing ibuprofen and acetaminophen in children with infectious fever.
- Data extraction included temperature changes at 1, 2, and 4 hours, and adverse event data; analyzed using mean difference (MD) and risk ratio (RR) with 95% confidence intervals.
Main Results:
- Ten studies involving 1773 patients were analyzed.
- Acetaminophen resulted in higher temperatures compared to ibuprofen at 1, 2, and 4 hours post-administration (significant P-values and high I² heterogeneity).
- No significant difference in adverse events was observed between ibuprofen and acetaminophen (RR = 0.8, 95% CI (0.52, 1.24), P = 0.32).
Conclusions:
- Ibuprofen demonstrates superior efficacy in reducing fever in children with infectious fever compared to acetaminophen.
- Both medications exhibit comparable safety profiles regarding adverse events.
- Findings support ibuprofen as a potentially more effective first-line antipyretic for pediatric infectious fever.
Background:
To evaluate ibuprofen and acetaminophen in the treatment of infectious fever in children.
Methods:
We searched randomized controlled trials and retrospective cohort studies comparing ibuprofen and acetaminophen in the treatment of infectious fever among children. Data were extracted from eligible studies. We sought to evaluate temperature after taking drugs in 1, 2, and 4 hours, respectively, and analyzed the adverse events. Results were expressed as mean difference(MD) and risk ratio (RR) with 95% confidence intervals.
Results:
Ten studies were included in this study with a total of 1773 patients. The results showed that acetaminophen had higher temperature than ibuprofen after 1 hour (The overall mean difference was -0.29 with 95% CI (-0.49, -0.09). The P value of the overall effect was = 0.004, I 2 = 91%), 2 hours (MD = -0.46, 95% CI (-0.67, -0.25), P < 0.00001, I 2 = 95%), and 4 hours (MD = -0.57, 95% CI (-0.82, -0.33), P < 0.00001, I 2 = 97%). There is no difference between two drugs in the adverse events (RR = 0.8, 95% CI (0.52, 1.24), P = 0.32, I 2 = 0%). The sensitivity analysis and funnel plot showed that our study was robust and had low publication bias.
Conclusion:
Our study suggested that ibuprofen is more effective than acetaminophen in children with infectious fever.
