Osteoarthritis is a degenerative joint disease characterized by cartilage breakdown, joint inflammation, and associated pain and stiffness. Treatment focuses on symptom management and improving joint function.
First-line recommendations according to the 2019 American College of Rheumatology (ACR) management guidelines include exercise, weight loss, physical therapy, as well as pharmacotherapy topical and oral NSAIDs (nonsteroidal anti-inflammatory drugs).
First-line recommendations:
Topical NSAIDs: Effective for localized pain relief, particularly in hand and knee OA. Apply diclofenac gel 1% (FDA NDA 22122/S-014) topically 2-4 times daily.
Oral NSAIDs: Used for more severe pain when topical agents are insufficient. Examples include ibuprofen 200-400 mg every 6-8 hours as needed, or naproxen 220 mg twice daily. Use with caution if gastrointestinal or cardiovascular risks are present. Naproxen sodium 220mg (FDA ANDA 204872).
Second-line recommendations:
Acetaminophen: Considered for mild-to-moderate pain relief. Dose: 500-1000 mg every 6-8 hours as needed, not exceeding 3000 mg/day. Acetaminophen 650 mg (FDA M013).
Capsaicin cream: Capsaicin is a potential alternative for osteoarthritis (OA) pain not relieved with acetaminophen or for people who cannot tolerate or are reluctant to use oral medications, Apply topically to the affected joint 3-4 times daily for pain relief. Capsaicin 0.025% with menthol gel (FDA M017).
Interventions:
Intra-articular corticosteroids: Effective for reducing joint inflammation and pain in patients with acute flares. Administered by a healthcare professional.
Duloxetine: FDA-approved for chronic musculoskeletal pain, including OA. Dose: 30-60 mg orally once daily.
Joint replacement if refractory pain and loss of function in large joint
