Gout Flashcards
Define gout
type of arthritis caused by a buildup of uric acid crystals primarily in the joints. UA is produced as an end-product of purine metabolism. purines are present in many foods, and they make up one of the base pairs of DNA
normal serum UA
2-6.5 mg/dL in females
3.5-7.2 mg/dL in males
foods to avoid in gout
organ meats
high-fructose corn syrup
alcohol
What goal UA do drugs target
<6 mg.dL
drugs that increase UA
ASA diuretics niacin pyrazinamide pancreatic enzyme products CNIs chemotherapy
Acute gout treatment
NSAID
systemic steroid
cholchicine
ppx for gout
xanthine oxidase inhibitors
- allopurinol
- febuxostat
define tophi
UA crystals that form under the skin in long-term gout
Important point to remember for allopurinol
Asians should be screened for HLA-B*5801 allele for hypersensitivity reactions
MOA of allopurinol
decrease uric acid production
drugs used for chronic urate lowering therapy
xanthine oxidase inhibitors
uricosurics
recombinant uricase
list uricosurics
lesinurad
probenacid
uricosurics MOA
inhibit reabsorption of uric acid in the kidneys which increase uric acid excretion
recombinant uricase MOA
convert uric acid to allantoin which is excreted
list recombinant uricase
pegloticase
