Osteoarthritis Treatment Guidelines

Introduction to Osteoarthritis Management

  • The British Medical Journal recommends exercise and physical activity focusing on local muscle strengthening and general aerobic fitness as a first-line treatment for osteoarthritis 1, 2, 3
  • Weight loss interventions are recommended for overweight or obese patients with osteoarthritis 1, 2
  • Education about the condition and self-management strategies is also a first-line treatment for osteoarthritis 2

Pharmacological Treatments for Osteoarthritis

  • Paracetamol (acetaminophen) is recommended as a second-line pharmacological treatment for osteoarthritis, with regular dosing as needed 1, 2, 4
  • Topical NSAIDs are recommended for knee and hand osteoarthritis 1, 2
  • Oral NSAIDs/COX-2 inhibitors, such as etoricoxib, are recommended when paracetamol or topical NSAIDs are insufficient 1, 2, 5
  • The British Medical Journal recommends prescribing oral NSAIDs/COX-2 inhibitors with a proton pump inhibitor for gastroprotection 1, 5

Etoricoxib Safety Profile

  • Etoricoxib has a better gastrointestinal safety profile than non-selective NSAIDs 6
  • The Annals of the Rheumatic Diseases notes that all COX-2 inhibitors and NSAIDs carry cardiovascular risk that must be evaluated 7
  • Etoricoxib should be used at the lowest effective dose (60mg for OA) for the shortest possible duration 1, 2

Risk Assessment and Monitoring

  • The British Medical Journal recommends evaluating gastrointestinal risk factors before prescribing NSAIDs/COX-2 inhibitors 1, 5
  • The Annals of the Rheumatic Diseases suggests assessing cardiovascular risk factors, particularly uncontrolled hypertension, before prescribing NSAIDs/COX-2 inhibitors 7
  • Renal function, especially in elderly patients, and hepatic function should be considered before prescribing NSAIDs/COX-2 inhibitors 1, 2, 5
  • Regular assessment of pain relief and functional improvement is recommended during treatment with NSAIDs/COX-2 inhibitors 1, 2
