Gout Treatments Flashcards
Besides NSAIDs and corticosteroids, name 5 drugs that are used to treat gout.
Colchicine, probenecid, allopurinol, febuxostat, pegloticase
Name 3 drugs/drug classes that are used to treat acute gouty arthritis.
NSAIDs, corticosteroids, and colchicine
Name 4 drugs that are used to treat chronic tophaceous gout.
Probenecid, allopurinol, febuxostat, pegloticase
How does colchicine cause the inibition of leukocyte migration, phagocytosis, and cytokine release in acute gouty arthritis? How many hours does it take to start working?
By inhibiting tubulin polymerization; 12-24 hours
Which therapy for chronic tophaceous gout is an uricosuric agent, meaning that it increases the rate of excretion of uric acid? How does it work?
Probenecid; competes with uric acid in the renal tubule to prevent its reabsorption
Which 2 therapies for chronic tophaceous gout are uric acid synthesis inhibitors? Which one is a non-purine, non-competitive antagonist of xanthine oxidase?
Allopurinol and febuxostat; febuxostat
Does allopurinol inhibit uric acid synthesis by competitive or non-competitive inhibition of xanthine oxidase?
Both: allopurinol itself is a competitive inhibitor, while its metabolite alloxanthine is a non-competitive inhibitor
Which therapy for chronic tophaceous gout is a recombinant uricase that directly metabolizes uric acid? What does it convert the uric acid into?
Pegloticase; allantoin
Which 2 therapies for chronic tophaceous gout can cause an initial attack of acute gouty arthritis as they mobilize the urate crystals?
Probenecid and allopurinol
Which gout therapy can cause nausea, vomiting, abdominal pain, and diarrhea; as well as peripheral neuropathy and neutropenia with long-term use?
Colchicine
Which gout therapy can cause GI irritation and decreased secretion of some weak acids, such as penicillin?
Probenecid
Which gout therapy is the newest, most expensive, and can also cause side effects of nausea, rash, and arthralgias?
Febuxostat
Which drug, stabilized by polyethylene glycol, is currently used on chronic gout that is refractory to all other therapies?
Pegloticase
