Transcript of Gout Drugs
AGENTS USED TO TREAT HYPERURICEMIA AND
GOUT
GOUT -a chronic metabollic disease associated
with the development of hyperuricemia, the
presence of abnormally elevated
amounts of uric acid in the blood
HYPERURICEMIA -may arise because of a reduction in the renal elimination of uric acid, an increase in uric acid production, or a
combination of these two factors
URIC ACID is an agent formed in the body by protein breakdown
-either be derived from dietary protein sources or from the breakdown of body
tissues
-not metabolized by the body
-it is generally excreted in the urine
In GOUT, uric acid precipitates from saturated body fluids as crystals
(TOPHI) which deposits in tissues and joints
This may cause GOUTY
ARTHRITIS, a condition
characterized by inflammation at the
site of crystal deposition and acute joint pain
MANAGEMENT OF ACUTE GOUTY ARTHRITIS
COLCHICINE
-drug of choice for acute attack of gout-particularly beneficial in clients who are hypersensitive to aspirin and NSAIDs
-Colchicine relieves pain and confirms the diagnosis of gout
CONTROL OF HYPERURICEMIA
-aimed at reducing serum urate levels to below 6mg/dl
-at this level, tophi do not form within the joints and tissues of the body
CONTROL OF HYPERURICEMIA
URICOSURIC AGENTS (Probenecid, Sulfinpyrazone) – increase the urinary
excretion of uric acid
XANTHINE OXIDASE INHIBITORS (Allopurinol) – preventing the formation
of uric acid in the body
URICOSURIC AGENTS
Example: Probenecid (Benemid), Sulfinpyrazone (Anturane)
-these agents increase uric acid excretion by preventing the
reabsorption of uric acid in the renal tubules
NURSING IMPLICATIONS:
-encourage client to drink large volumes of water (10-12 8-ounce glasses) daily to prevent increase UA concentration in the urine
NURSING IMPLICATIONS:
-Sulfinpyrazone (Anturane) is capable of affecting platelet function
XANTHINE OXIDASE INHIBITORS
Example: Allopurinol (Zyloprim)
-interferes with the conversion of purines to uric acid by inhibiting the
enzyme xanthine oxidase
NURSING IMPLICATIONS:
-May cause skin rashes and/or hepatotoxicty in some clients
-Avoid foods that are rich in purine
SOME FOODS HIGH IN PURINES

KEY NURSING IMPLICATIONS IN THE USE OF HYPERURICEMIA
Assess the client taking colchicine for nausea and loose stools
Local tissue reactions can occur with infiltration of colchicine
Treatment should be initiated at the first sign of an attack of gout
KEY NURSING IMPLICATIONS IN THE USE OF HYPERURICEMIA
Factors that may produce attacks include a high fat diet, purine rich foods, thiazide diuretics, liver extracts, penicillin, levodopa, ethambutol
Aspirin is avoided when probenecid or sulfinpyrazone is used
KEY NURSING IMPLICATIONS IN THE USE OF HYPERURICEMIA
Fluid intake is encouraged during probenecid, sulfinpyrazone, and allopurinol therapy
Notify the prescriber promptly if skin rash occurs during allopurinol
