Aspirin
1) Use: Low dose (s syndrome in children with viral infections.

NSAIDs (Ibuprofen, naproxen, indomethacin, ketorolac)
1) Use: Antipyretic, analgesic, anti-inflammatory. Indomethacin is used to close a PDA.
2) Class/MOA: Reversibly inhibits cycooxygenase (both COX-1 and COX-2). Block prostaglandin synthesis.
3) Side effects/ADEs: Renal damage, fluid retention, aplastic anemia, GI distress, ulcers.
4) Fun Facts
1) uses 2) class/ MOA 3) ADE 4)Fun fact/note
COX-2 Inhibitor (celecoxib)
1) Use: Rheumatoid and osteoarthritis; patients with gastritis or ulcers.
2) Class/MOA: Reversibly inhibits the cycooxygenase (COX) isoform 2, which is found in inflammatory cells and vascular endothelium and mediates inflammation and pain; spares COX-1, which maintains the gastric mucosa. Thus, should not have the corrosive effects of other NSAIDs on the GI lining.
3) Side effects/ADEs: Increased risk of thrombosis. Sulfa allergy. Less toxicity to GI mucosa (lower incidence of ulcers, bleeding than NSAIDs).
4) Fun Facts
1) uses 2) class/ MOA 3) ADE 4)Fun fact/note
Acetaminophen
1) Use: Antipyretic, analgesic, but lacking anti-inflammatory properties. Used instead of aspirin to prevent Reye’s syndrome in children with viral infections.
2) Class/MOA: Reversibly inhibits cycooxygenase, mostly CNS. Inactivated peripherally.
3) Side effects/ADEs: Overdose produces hepatic necrosis, acetaminophen metabolite depletes glutathione and forms toxic tissue adducts in the liver. N-aceylcystine is antidote - regenerates glutathione.

Bisphosphonates (Etidronate, pmidronate, alendronate, risedronate, zoledronate (IV))
1) Use: Maligancy associated hypercalcemia, Paget’s diseases of the bone, postmenopausal osteoproposis.
2) Class/MOA: Inhibit osteoclastic activity; reduces both formation and resorption of hydroxyapatite.
3) Side effects/ADEs: Corrosive esophagitis (except zoledronate), nausea, diarrhea, osteonecrosis of the jaw.

Chronic Gout Drug (Probenecid)
1) Use: Chronic Gout (urate lowering therapy)
2) Class/MOA: Inhibits resorption of uric acid in the PCT (also inhibits secretion of penicillin)
3) Side effects/ADEs:

Chronic Gout Drug (Allopurinol)
1) Use: Chronic Gout (urate lowering therapy)
2) Class/MOA: Inhibits xanthine oxidase, decreases conversion of xanthine to uric acid. Also used in lymphoma and leukemia to prevent tumor lysis-associated urate nephropathy. Increases concentration of azathioprine and 6-MP (both normally metabolized by xanthine oxidase).
3) Side effects/ADEs: Do not dive salicylates; all but the highest dosages depress uric acid clearance. Even high doses (5-6 g/day) have only minor uricosuric activity.

Chronic Gout Drug (Febuxostat)
1) Use: Chronic Gout (urate lowering therapy)
2) Class/MOA: Inhibits xanthine oxidase

Acute Gout Drug (Colchicine)
1) Use: Acute Gout (urate lowering therapy)
2) Class/MOA: Binds and stabilizes tubulin to inhibit polymerization, impairing leukocyte chemotaxis and deregulation.
3) Side effects/ADEs: GI side effects, especially if given orally (note: Indomethacin is less toxic, also used in acute gout).
4) Fun Facts

Acute Gout Drug (NSAIDs)
1) Use: Acute Gout (urate lowering therapy)
2) Class/MOA: Naproxen.

The alpha inhibitors (Entanercept)
1) Use: Rheumatoid arthritis, psoriasis, ankylosing spondylitis.
2) Class/MOA: Recombinant form of human TNF receptor that binds TNF.
3) Side effects/ADEs: All TNF alpha inhibitors predispose to infection including reactivation of latent TB since TNF blockade prevents activation of macrophages and destruction of phagocytosed microbe.
4) Fun Facts: EntanerCEPT is a TNF decoy reCEPTor.
1) uses 2) class/ MOA 3) ADE 4)Fun fact/note
The alpha inhibitors (Infliximab)
1) Use: Chron’s disease, rheumatoid arthritis, ankylosing spondylitis.
2) Class/MOA: Anti-TNF antibody
3) Side effects/ADEs: All TNF alpha inhibitors predispose to infection including reactivation of latent TB since TNF blockade prevents activation of macrophages and destruction of phagocytosed microbe.

The alpha inhibitors (Adalimumab)
1) Use: Psoriasis, rheumatoid arthritis, ankylosing spondylitis
2) Class/MOA: Anti-TNF antibody
3) Side effects/ADEs: All TNF alpha inhibitors predispose to infection including reactivation of latent TB since TNF blockade prevents activation of macrophages and destruction of phagocytosed microbe.
