"June 28, 2010 -- Older patients who take Avandia have a higher risk of death, heart failure, and stroke than patients taking Actos, a similar diabetes drug, a new study finds.
It's far from the first study to address Avandia safety, but"...
Monotherapy and Combination Therapy
Important Limitations of Use
ACTOS exerts its antihyperglycemic effect only in the presence of endogenous insulin. ACTOS should not be used to treat type 1 diabetes or diabetic ketoacidosis, as it would not be effective in these settings.
DOSAGE AND ADMINISTRATION
Recommendations for All Patients
ACTOS should be taken once daily and can be taken without regard to meals.
The recommended starting dose for patients without congestive heart failure is 15 mg or 30 mg once daily.
The recommended starting dose for patients with congestive heart failure (NYHA Class I or II) is 15 mg once daily.
The dose can be titrated in increments of 15 mg up to a maximum of 45 mg once daily based on glycemic response as determined by HbA1c.
After initiation of ACTOS or with dose increase, monitor patients carefully for adverse reactions related to fluid retention such as weight gain, edema, and signs and symptoms of congestive heart failure [see BOXED WARNING and WARNINGS AND PRECAUTIONS].
Liver tests (serum alanine and aspartate aminotransferases, alkaline phosphatase, and total bilirubin) should be obtained prior to initiating ACTOS. Routine periodic monitoring of liver tests during treatment with ACTOS is not recommended in patients without liver disease. Patients who have liver test abnormalities prior to initiation of ACTOS or who are found to have abnormal liver tests while taking ACTOS should be managed as described under WARNINGS AND PRECAUTIONS [see WARNINGS AND PRECAUTIONS and CLINICAL PHARMACOLOGY].
Concomitant Use with an Insulin Secretagogue or Insulin
If hypoglycemia occurs in a patient co-administered ACTOS and insulin, the dose of insulin should be decreased by 10% to 25%. Further adjustments to the insulin dose should be individualized based on glycemic response.
Concomitant Use with Strong CYP2C8 Inhibitors
Coadministration of ACTOS and gemfibrozil, a strong CYP2C8 inhibitor, increases pioglitazone exposure approximately 3-fold. Therefore, the maximum recommended dose of ACTOS is 15 mg daily when used in combination with gemfibrozil or other strong CYP2C8 inhibitors [see DRUG INTERACTIONS and CLINICAL PHARMACOLOGY].
