Introduction
Tradename: Avandia. Medication Guide to be provided with each prescription
Indications
- adjunct to diet & exercise to improve diabetic control in patients with diabetes mellitus type 2
- indicated as monotherapy or for use in combination with metformin or insulin[7]
- for patients inadequately controlled on a maximum dose of metformin, rosiglitazone should be added to rather than substituted for metformin
- psoriasis (not FDA-approved use)[9]
Contraindications
(cautions)
Dosage
- 4 mg PO QD-BID
- max dose: 4 mg if used in combination with insulin[7]
- reduce insulin by 10-25% if hypoglycemia develops[7]
Tabs: 2, 4, 8 mg
Pharmacokinetics
- bioavailability after oral dose is 99%
- 99.8% bound to serum proteins
- metabolized in the liver largely by cyt P450 2C8 with cyt P450 2C9 playing a minor role
- N-demethylation & hydroxylation followed by conjugation
- t1/2: 103-158 hours
elimination via liver
1/2life = 103-158 hours
protein binding = 99.8 %
Monitor
- LFTs at start, then every 2 months for 1st year, then periodically
- discontinue if AST > 2.5 x upper limit of normal
Adverse effects
- reversible elevations in ALT 3X (0.2%)
- No evidence of hepatotoxicity
- anemia: decreases in hemoglobin of 1.0 g/dL
- fluid retention & edema
- may exacerbate heart failure[4][6][8]
- may exacerbate heart failure in patients with class 1 or 2 NYHA Heart failure[13]
- may increase risk of heart failure[18][22][32]
- may increase serum triglycerides < 15%[10]
- diabetic macular edema [12]
- most have peripheral edema
- may resolve with discontinuation
- may increase risk of fractures (females)[14][22]
- may increase risk of myocardial infarction in patients with type 2 diabetes (odds ratio 1.43)[15][16],
- No increase risk of myocardial infarction[18][22][31]
- cardiovascular risk in elderly confirmed[20] for CHF (relative risk, 1.6) or AMI (RR, 1.4) & for death (RR, 1.29)
- risk of osteoporosis & fractures in women[23]
- increased risk of macular edema (RR = 6.5 at 1 year)[30]
Drug interactions
- risk of heart failure increased when used in combination with insulin[4]
- drug interaction(s) of gemfibrozil with rosiglitazone
- drug interaction(s) of fluoroquinolones with hypoglycemic agents
Mechanism of action
- thiazolidinedione
- PPAR-gamma agonist
- PPAR-gamma regulates transcription of insulin-responsive genes
* PPAR: peroxisome proliferator-activated receptor
More general terms
Additional terms
- metformin/rosiglitazone (Avandamet)
- peroxisome proliferator-activated receptor gamma; PPAR-gamma; nuclear receptor subfamily 1 group C member 3 (PPARG, NR1C3)
