Q

Class;Mechanism;Therapeutics;SideEffects

Glucocorticoids
(Corticosteroids)

A

DMARD 1. Inhibits phospholipase A2 (inhibiting release of arachidonic acid and, thus, formation of prostaglandins)
2. Inhibits cytokine production (which prevents induction of COX-2) Rheumatoid arthritis; acute gouty arthritis (intraarticular injection for relief of acute monoarticular gout) Cushingoid symptoms — Started initially (fast acting) before other drugs become effective
Can give orally or intra-articularly

Q

Class;Mechanism;Therapeutics;SideEffects

Methotrexate (Trexall)

A

DMARD
(Immunosuppressive) 1. Inhibition of aminoimidazolecarboxamide (AICAR) transformylase and
thymidylate synthetase, with secondary effects on PMN chemotaxis
2. Causes adenosine accumulation, which inhibits inflammation Rheumatoid arthritis Nausea, stomatitis, hepatotoxicity (rare) — Takes several weeks to start working; “gold standard” of therapy

19
Q

Class;Mechanism;Therapeutics;SideEffects

Colchicine (Colcrys)

A

— Prevents tubulin polymerization & leads to inibition of leukocyte migration, phagocytosis, and release of cytokines Acute gouty arthritis Long-term use causes peripheral neuropathy & neutropenia Nausea, vomiting, abdominal pain, troublesome diarrhea Works in 12-24 hours!
