Tramadol (with or without acetaminophen) efficacy and harm: Systematic review and meta-analysis

Area of Science:

• Pharmacology
• Pain Management
• Clinical Trials

Background:

• Tramadol, often combined with acetaminophen, is used for pain relief.
• Its efficacy and safety relative to NSAIDs and opioids require thorough evaluation.

Purpose of the Study:

• To compare the efficacy and safety of tramadol (with or without acetaminophen) against NSAIDs, opioids, and acetaminophen alone in adult pain management.

Main Methods:

• Systematic review and meta-analysis of double-blind, randomized controlled trials (RCTs).
• Searched Ovid MEDLINE, Embase, and Cochrane databases up to August 2022.
• Included 37 RCTs (N=7156) assessing pain reduction, adverse events, and withdrawals.

Main Results:

• Tramadol showed no significant difference in efficacy or harm compared to opioids.
• Tramadol was less effective for pain reduction and had more adverse events than NSAIDs.
• Insufficient evidence existed for fatal serious adverse events, dependence, quality of life, or functional improvement.

Conclusions:

• Tramadol with or without acetaminophen is not significantly different from other opioids but is less effective and tolerated than NSAIDs.
• Study limitations including short duration and small sample sizes affect the scientific validity of the findings.
