Rheumatoid Arthritis Treatment Flashcards
Therapeutic Categories in Rheumatoid Arthritis
NSAID’s
Disease modifying anti-rheumatic drugs
Biologics
Corticosteroids
How long do Disease Modifying Anti-Rheumatic Drugs take to work
3 months
Examples of DMARD’s
Methotrexate Sulfalazone Hydroxychloroquine Leflunomid Gold Salts Penicillamine
What DMARD’s are commonly used and why
Methotrexate and hydroxychloroquine are often used due to their balance between toxicity and efficacy
Approach to Management
There should be an early and aggressive intervention, effective suppression of inflammation. This will improve symptoms and prevent joint damage and disability.
Methotrexate in Rheumatoid Arthritis
Effective, well tolerated and cheap. It is the cornerstone of combination therapy (DMARD and biologic).
Biologics
Large complex proteins which need to be given parenterally. They work rapidly, are generally well tolerated but have important toxicities.
Key biologics
TNFalpha inhibitors (etanercept) IL-1 Inhibitors (Anakinra) Anti B cell therapies (Rituximab) Anti T cell therapies (abatacept) IL-6 inhibitors (tocilizumab)
Efficacy of Biologics
Better when prescribed alongside Methotrexate
Toxicity of Biologics
Risk of infection and malignancy
Corticosteroids in RA
Short term benefit. These are rarely appropriate as single drug therapy.
