Anti Inflammatory And Corticoids Flashcards
3 goals of RA therapy?
Stop inflammation, relieve symptoms, and prevent joint and organ damage
7 non drug therapies for RA?
Rest, exercise, PT, OT, nutrition and diet, bone protection, lower CV risk.
What is drug of choice for additional pain relief? What is the first drug of choice for RA and why?
Acetaminophen
NSAIDS because of anti inflammatory action and pain relief
3 mechanism of actions for prednisone?
Through GR
GR complexing with NFKB and AP1
Lipocortin, an inhibitor of PLA2
What is the clinical application for using prednisone?
Autoimmune diseases like RA
Relieve pain and inflammation while waiting for DMARD effects
Flare ups
How is prednisone converted to its active form?
The liver converts prednisone, which is a pro drug, to prednisone
What is the idea in mind when using prednisone for active RA?
Use it for a short time to quickly minimize disease activity while waiting for DMARDs to kick in. Not a great idea to use chronic, but if you are, use it with DMARDs and less than 5mg a day.
How many joints are involved in mild RA and what is the initial treatment for it?
5 and under
DMARD monotherapy and consider giving glucos for flare ups
How many joints involved in moderate RA, what are two big differences between mild and moderate as far as labs, what would be initial treatment for moderate?
Greater than 5
Rheumatoid factor and antibodies against CCP
Combination DMARDS with glucos for flare ups or
TNF inhibitor with glucos for flare ups, maybe MTX
Non TNF maybe MTX glucos for flare ups
What is the mechanism of action of methotrexate, 3 things?
Becomes MTX PG which leads to blocking thymidine synthesis, blocks purine synthesis, and adenosine activating purinergic G protein receptors for ani inflammatory effect.
What is unique to methotrexate effect and what is the most significant clinical application?
Quickest acting of DMARDs 3-6 weeks
First line drug of choice for RA
2 most common adverse effects of Methotrexate and what 3 adverse effects with chronic administration?
Mucosal ulcers and nausea
Cytopenias (particularly WBC), cirrhosis, and pneumonia
How is sulfasalazine metabolized and what is the clinical application for it?
It is metabolized to 5 ASA (active agent in IBD) and sulfapyridine (active agent in RA)
Early mild RA with methotrexate and/or hydroxy. This is the triple therapy.
2 most common adverse effects of sulfasalazine?
GI and leukopenia
MOA of leflunomide and its clinical application?
Inhibition of DHODH to block synthesis of rUMP that causes cell arrest in autoimmune lymphocytes (particular T cells).
Alternative nonbiological DMARD to methotrexate, so second choice drug.
Can be used in combination with DMARDs as well.
