Drugs for Rheumatoid Arthritis Flashcards
Classes of drugs used in R.A.
NSAIDS, Glucocorticoids, and DMARDs
Indications of NSAIDs in R.A.
Reduce pain and inflammation
Indications of Oral corticoids in R.A.
Relieve joint symptoms and control systemic manifestations; chronic use may cause many complications
True or False: NSAIDs and corticosteroids do not prevent disease progression or joint destruction.
True
Which group of drugs used in R.A. can reduce or prevent joint damage?
DMARDs
MOA of DMARDs
Delay and possible stop disease progression, but no immediate analgesic effects
Time-line of DMARD effects
6 weeks - 6 months
First DMARD usually prescribed for mild, moderate, or severe R.A.
Methotrexate
When are biologic DMARDs used?
Moderate to severe R.A.
AE of Methotrexate in R.A. use
Minimized because doses are much lower than when used for chemotherapy
Used in combination therapy with Methotrexate for R.A. in patients who do not respond to Methotrexate alone
Leflunomide; as effective as Methotrexate at reducing disease activity and progression
Least toxic of all DMARDs
Hydroxychloroquine
Least effective as mono therapy for R.A.; usually combined with Methotrexate and Sulfasalazine
Hydroxychloroquine
Moderately effective against mild R.A. and may take 3-6 months to show effects
Hydroxychloroquine
Sulfa drug use in R.A.; benefits show after 2-3 months
Sulfasalazine
Limited use in R.A. due to nephrotoxicity and food and drug interactions
Cyclosporine
Used for refractory R.A.
Azathioprine
Use in R.A. limited to most severe cases due to increased risk of infection and malignancy
Cyclophosphamide
Non-Biological DMARDs
Methotrexate, Leflunomide, Hydroxychloroquine, Sulfasalazine, Cyclosporine, Azathioprine, and Cyclophosphamide
Biologic DMARDs
Adalimumab, Infliximab, Etanercept, Anakinra, Rituximab, and Abatacept
Anti-TNF DMARDs
Adalimumab, Infliximab, and Etanercept
Which TNF is most important in inflammatory process of R.A.?
TNF-alpha
TNF inhibitors can be combined with drug to cause synergistic effects?
Methotrexate i.e. Methotrexate + Rituximab
True or False: TNF inhibitors act more quickly than non-biologic DMARDs.
True
Effective in patients who did not respond to non-biologic DMARDs or anti-TNF agents
Abatacept
Biologic DMARD approved for moderate to severe R.A.
Anakinra; modest effects
Mainly used as bridge drugs for symptom relief
NSAIDs
Indications for Glucocorticoids in R.A.
Short courses at low doses for symptomatic relief until effects of DMARDs kick in; intra-articular injection for relieve of acutely inflammated R.A. joint
Initial Treatment of R.A.
Non-biologic DMARD (Methotrexate) + NSAID or corticoid for symptom control
Treatment for mildest cases of R.A.
Hydrochloroquine and Sulfasalazine
1st line treatment of moderate to severe R.A.
TNF inhibitors
Combination therapy in R.A.
Weekly Methotrexate + other agent
Hydroxychloroquine + Methotrexate and Sulfasalazine
AE of combination therapy
Leflunamide + Methotrexate increases hepatotoxicity; monitor closely
Effective combination therapies
Methotrexate +
Hydroxychloroquinolone + Sulfasalazine or individually
Cyclosporine
Leflunomide
TNF Inhibitor
