Evidence
Emergency Medicine
- Oral tramadol combined with acetaminophen administered early in the ED triage was associated with a decrease in IV morphine requirement and increased satisfaction among ED patients with acute pain compared to patients taking acetaminophen alone[1]
- The use of tramadol in an emergency setting is not well studied, and this literature review concluded that tramadol does not offer any particular benefits over existing analgesics for the majority of emergency pain relief situations[2]
- The Extended Release formulation of tramadol has proven efficacy in chronic pain conditions such as osteoarthritis and low back pain, with a favorable side effect profile. Clinical trials have also demonstrated an improvement in pain related sleep disturbances and physical function in those with chronic pain from oseoarthritis and low back pain.[3]
