Acute Gout
- start w/ NSAIDs- naproxen and indomethacin
- next use Colchicine
- next use Glucocorticoids
Explain general preventioin treatment of recurrent gout
- lifestyle changes to reduce urate
- drugs
NSAIDs used for acute gout and when do you start them
Naproxen, indomethacin, and celecoxib
Start w/in 48 hr of onset
Colchicine MOA Uses AE CI
Colchicine
MOA- binds tubulin to block microtubule formation which will inhibit leukocyte migration
Uses- used for acute gout in pt intolerant to NSAIDs
AE- GI
CI- renal/hepatic impairment
Explain the urate-lowering treatment of gout?
Start w/ allpurinol, switch to febuxostat if allopurinol is not tolerated, then as last resort use pegloticase
Allopurinol
MOA
Uses
AE
Allopurinol
MOA- met into alloxanthine which inhibits xanthine oxidase to inc excretion of hypoxanthine and xanthine
Uses- recurrent gout and chem-induce hyperuricemia
AE- rash, acute gout, hypersensitivity if HLA-B+ (asian)
Febuxostat
MOA
Uses
Febuxostat
MOA- inhibits xanthine oxidase to in excretion of xanthine and hypoxanthine
Uses- use in pt who don’t tolerate allopurinol
Pegloticase MOA Uses Kinetics AE
Pegloticase
MOA- attaches to methoxypolyetheylene glycol to convert uric acid into allantoin
Uses- chronic gout refractory to conventional therapy
Kinetics- IV every 2 wks
AE- infusion rxn (premed w/ gluco or antihistamine), acute gout
Probenecid
MOA
uses
AE
Probenecid
MOA- blocks urate reabsorption, inc fractional excretion of urate and dec plasma urate concentration
Uses- urate underexcreters w/ GFR>60 w/o stones
AE- kidney stones, acute gout, sulfa hypersensitivity
