NSAID STEPS - Safety

A
  • In patients at risk of or with existing cardiovascular disease, NSAID’s such as naproxen, ibuprofen and piroxicam are not associated with an increased risk of cardiovascular disease.
  • all NSAID’s carry the risk of causing changes in renal function
  • Patients with a greater risk of GI toxicity include:
    • Elderly patients
    • Patients with a history of GI bleeds
    • Patients concurrently using anticoagulants, antiplatelet drugs, and/or systemic corticosteroids

Q

NSAID STEPS - Efficacy

A
  • Available NSAIDs are equally effective, but individuals’ responses to agents will vary

Q

NSAID STEPS - Preference (Pearls)

A
  • Celecoxib has fewer GI adverse events than other NSAIDs; however, it is no more effective at reducing pain and inflammation
  • Adding misoprostol to an NSAID will decrease the risk of GI ulceration
  • Adding a PPI to an NSAID will decrease nonulcerative symptoms
  • If a patient does not respond to NSAID therapy (after an appropriate 14-28 day trial), providers should consider trying other NSAIDs before concluding therapeutic failure.

Q

Corticosteroid STEPS - Efficacy

A
  • Short-term (weeks), low-dose (less than 15mg of prednisone daily) corticosteroids are effective for symptoms flare

  • Higher corticosteroid doses ma be warranted to treat symptoms of sever or advanced disease (e.g., presence of vasculitis
  • Intra-articular injections may be beneficial, but limit injections in joint to more than every 3-4 months

Q

Methotrexate STEPS - Efficacy
