A Comparison of the Efficacy and Safety of Non-Steroidal Anti-Inflammatory Drugs versus Acetaminophen in Symptom Relief for the Common Cold: A Meta-Analysis of Randomized Controlled Trial Studies

Abstract

BackgroundNon-steroidal anti-inflammatory drugs (NSAIDs) and acetaminophen are widely used for common cold symptom relief. The objective of this study was to evaluate and compare the efficacy and safety of acetaminophen and NSAIDs in common cold symptom relief using meta-analysis of randomized controlled trial.MethodsWe searched MEDLINE (PubMed), Cochrane, EMBASE, CINAHL, KMbase, KoreaMed, National Assembly Library, and Riss4u for studies released through June 2012. Two authors independently extracted the data. To assess the risk of bias, the Cochrane Collaborations risk of bias tool was used. The Review Manager ver. 5.1 (RevMan) was used for statistics.ResultsWe identified 5 studies. The relative benefit for participants with pain relief was 1.00 (95% confidence interval [CI], 0.96 to 1.05) and I2 = 0%. The existence of the heterogeneity between studies was not important in this study, thus subgroup analysis was not implemented. The relative benefit for participants with rhinorrhea was 1.02 (95% CI, 0.77 to 1.35) and I2 = 0%, which also indicates the existence of heterogeneity was not important. The relative risk of adverse events was 1.14 (95% CI, 0.93 to 1.40), I2 = 0%. There was no apparent asymmetry in the funnel plot.ConclusionThere was no difference between NSAIDs and acetaminophen in common cold symptom relief.

Preclinical comparison of antinociceptive effects between ibuprofen, diclofenac, naproxen, and acetaminophen on acid-stimulated body stretching and acid-depressed feeding behaviors in rats

“…Clinical studies have been conducted to evaluate the effect of these drugs in different diseases. A meta-analysis study compared the efficacy of NSAIDs and acetaminophen in a model of inflammatory pain, and showed no significant difference between these medications (Choi et al , 2013). Another study showed comparable efficacy between ibuprofen (1200–3200 mg/day), diclofenac (100–200 mg/day), and naproxen (500–1500 mg/day) in the treatment of osteoarthritis (Morgan et al , 1993).…”
