amitriptyline (tricyclic antidepressant)
fluoxetine (SSRI)
cyclobenzaprine (muscle relaxer)

44
Q

A

Acetaminophen

68
Q
Drug that you need to monitor:
LFTs
Serum creatinine/BUN
Serum Salicylate concentration
Stool Guaiac
A

Aspirin

69
Q

MOA: reversible, alosteric competitive inhibitor of xanthine oxidase (converts xanthine to hypoxanthine which is converted to uric acid) AND also metabolized (oxidation by XO) to oxypurinol which is a non-competitive inhibitor of XO (when molecule is formed, it binds irreversibly to enzyme and kills it).

A

Allopurinol

70
Q

MOA: direct inhibitor of both the oxidized and reduced forms of xanthine oxidase and the enzyme-inhibitor complex is highly stable

A

Febuxostat

71
Q

MOA: small molecule that is secreted into the tubular fluid by an organic acid transporter; uric acid is secreted into the tubular fluid by a uric acid transporter (NOT affected by drug)—drug competes with uric acid for reabsorption at the brush border transporter (decreasing the amount of uric acid that is reabsorbed/increases uric acid excretion in the urine).

A

Probenecid

72
Q

MOA: This drug works by depolimerizaiton of microtubules of migrating cells so that the cells (PMN/WBC) coming toward the gout cannot move—this prevents the release of pro-inflammatory cytokines and STOPS the gout attack and can be used to prevent recurrence of gouty arthritis.

A

Colchicine

73
Q

MOA: COX inhibitor that inhibits leukocyte motility (blocks ability of immune response to attack uric acid crystals→ reduces pain associated with inflammatory response)

A

Indomethacin

74
Q

MOA: rapidly lowers serum levels of uric acid and reduces urinary excretion of uric acid; increases serum levels of allantoin and urinary excretion of allantoin (5 times more soluble than uric acid)

A

Pegloticase

75
Q

AE: increase incidence of active gout (crystals may dissolve and cause flare-ups—so give NSAID); hypersensitivity reactions (dermatitis, exfoliative dermatitis); effects on liver function (need LFTs every 6 weeks at start)

A

Allopurinol

76
Q

AE: transaminase elevations >3 times the upper limit

A

Febuxostat

77
Q

AE: patient needs to drink a lot of water to prevent kidney stones as the uric acid crystals in joints break down

A

Probenecid

78
Q

AE: GI disturbances (acute—sign you have given too much) and blood dyscrasias (chronic)

A

Colchicine

79
Q

AE: occur in 50% of patients: GI (N/V, ulcers); CNS (severe frontal HA); Hematopoietic disorders

A

Indomethacin

80
Q

AE: VERY EXPENSIVE; patients need to be prophylactically (with colcicine) protected because crystals can break down in joints and cause gout flares; not for patients with antibodies against the PEG moitey

A

Pegloticase

81
Q

Gout drug with longest half life.

A

Pegloticase

82
Q

Gout drug that will antagonize furosemide and HCTZ (diuretics).

A

Probenecid

84
Q

A

Allopurinol

85
Q

A

Febuxostat
