What is the best opioid (narcotic analgesic) and its dose for managing musculoskeletal (MSK) pain?

From the Guidelines

For acute moderate to severe musculoskeletal (MSK) pain, hydrocodone/acetaminophen 5/325mg, one tablet not more frequently than every 4 hours as needed, is a reasonable opioid option, as it is specifically mentioned in the CDC clinical practice guideline for prescribing opioids for pain 1. When managing MSK pain, it is crucial to prioritize non-opioid approaches first, including acetaminophen, NSAIDs, topical agents, physical therapy, and non-pharmacological interventions. The key principles in opioid prescribing for acute pain, as outlined in the CDC guideline 1, include:

• Prescribing immediate-release opioids at the lowest effective dose
• Limiting the duration of opioid use to the expected duration of pain severe enough to require opioids
• Maximizing the use of non-opioid pharmacologic and nonpharmacologic therapies
• Working with patients to prevent prolonged opioid use and planning for discontinuation
• Considering concurrent medical conditions and offering naloxone when appropriate Some important considerations for opioid use in MSK pain management include:
• Patient education on proper use, storage, and disposal of opioids
• Regular reassessment of pain and opioid use
• Checking prescription drug monitoring programs before prescribing opioids
• Discussing the risks of opioid use, including respiratory depression, physical dependence, addiction, and overdose
• Setting a clear goal for functional improvement alongside pain relief, with a plan for discontinuation of opioids when possible. It's also important to note that opioids are not recommended as first-line therapy for chronic MSK pain due to limited evidence of long-term efficacy and significant risks 1.

2 DOSAGE AND ADMINISTRATION

Dosage and Administation: 2. 1 Important Dosage and Administration Instructions Use the lowest effective dosage for the shortest duration consistent with individual patient treatment goals [see Warnings and Precautions (5)] Initiate the dosing regimen for each patient individually, taking into account the patient's severity of pain, patient response, prior analgesic treatment experience, and risk factors for addiction, abuse, and misuse [see Warnings and Precautions (5. 1)] . 2. 2 Initial Dosage Use of Oxycodone Hydrochloride Tablets as the First Opioid Analgesic Initiate treatment with oxycodone hydrochloride tablets in a dosing range of 5 to 15 mg every 4 to 6 hours as needed for pain.

The best opioid for managing musculoskeletal (MSK) pain is oxycodone, and its initial dose is 5 to 15 mg every 4 to 6 hours as needed for pain 2.

• The dose should be titrated based on the individual patient's response to their initial dose.
• Patients with chronic pain should have their dosage given on an around-the-clock basis to prevent the reoccurrence of pain.
• The dose can then be adjusted to an acceptable level of analgesia, taking into account side effects experienced by the patient.

From the Research

Opioid Options for MSK Pain

• Oxycodone/acetaminophen has been shown to provide slightly greater pain relief than acetaminophen alone for patients with acute musculoskeletal pain refractory to oral ibuprofen, but with more medication-related adverse events 3
• Hydrocodone may be a more effective analgesic than codeine in acute musculoskeletal pain, with significantly fewer treatment failures and less central nervous system side effects 4
• Oral oxycodone represents a feasible alternative to IV morphine in the treatment of severe acute musculoskeletal pain when difficult or delayed IV placement presents a barrier to treatment 5

Dosing Information

• Oxycodone 10 mg/acetaminophen 650 mg has been used as a second-line treatment for patients with acute musculoskeletal pain who did not respond to ibuprofen 600 mg 3
• Oral 0.125 mg/kg oxycodone has been compared to 0.1 mg/kg IV morphine for the initial treatment of acute musculoskeletal pain in the emergency department 5
• Hydrocodone 5 mg with 500 mg acetaminophen has been used to evaluate the efficacy and prevalence of side effects in acute musculoskeletal pain 4

Considerations for MSK Pain Management

• Non-opioid analgesics, such as ibuprofen and acetaminophen, are often used as first-line treatment for musculoskeletal pain, but may not provide adequate relief for all patients 6
• Opioids may be considered for patients with severe acute musculoskeletal pain, but their use should be carefully weighed against the potential risks and side effects 3, 5, 7
• Repeated assessment of pain levels and functional status is critical for optimal pain management, particularly in older adults with chronic non-malignant musculoskeletal pain 7
