pioglitazone and glimepiride

2 DOSAGE AND ADMINISTRATION Individualize the starting dose of pioglitazone and glimepiride tablets based on the patient's current regimen. ( 2.1 ) May adjust the dosing based on effectiveness and tolerability while not exceeding the maximum recommended daily dose of pioglitazone 45 mg and glimepiride 8 mg. ( 2.1 ) Pioglitazone and glimepiride tablets should be given in a single dose once daily with meals. ( 2.1 ) Obtain liver tests before starting pioglitazone and glimepiride tablets. If abnormal, use caution when treating with pioglitazone and glimepiride tablets, investigate the probable cause, treat (if possible) and follow appropriately. Monitoring liver tests while on pioglitazone and glimepiride tablets is not recommended in patients without liver disease. ( 5.5 ) 2.1 Recommendations for All Patients Pioglitazone and glimepiride tablets should be taken once daily with the first main meal. Pioglitazone and glimepiride tablets are available as a 30 mg pioglitazone plus 2 mg glimepiride or a 30 mg pioglitazone plus 4 mg glimepiride tablet. If therapy with a combination tablet containing pioglitazone and glimepiride is considered appropriate the recommended starting dose is: 30 mg/2 mg or 30 mg/4 mg once daily and gradually titrated, as needed, after assessing adequacy of therapeutic response and tolerability, for patients inadequately controlled on glimepiride monotherapy: 30 mg/2 mg or 30 mg/4 mg once daily and gradually titrated, as needed, after assessing adequacy of therapeutic response and tolerability, for patients inadequately controlled on pioglitazone monotherapy: 30 mg/2 mg once daily and gradually titrated, as needed, after assessing adequacy of therapeutic response and tolerability, for patients who are changing from combination therapy of pioglitazone plus glimepiride as separate tablets: pioglitazone and glimepiride tablets should be taken at doses that are as close as possible to the dose of pioglitazone and glimepiride already being taken, for patients currently on a different sulfonylurea monotherapy or switching from combination therapy of pioglitazone plus a different sulfonylurea (e.g., glyburide, glipizide, chlorpropamide, tolbutamide, acetohexamide): 30 mg/2 mg once daily and adjusted after assessing adequacy of therapeutic response. Observe for hypoglycemia for one to two weeks due to the potential overlapping drug effect. for patients with systolic dysfunction, the lowest approved dose of pioglitazone and glimepiride tablets should be prescribed only after titration from 15 mg to 30 mg of pioglitazone has been safely tolerated. After initiation of pioglitazone and glimepiride tablets or with dose increase, monitor patients carefully for hypoglycemia and 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 (5.7) ] . Liver tests (serum alanine and aspartate aminotransferases, alkaline phosphatase, and total bilirubin) should be obtained prior to initiating pioglitazone and glimepiride tablets. Routine periodic monitoring of liver tests during treatment with pioglitazone and glimepiride tablets is not recommended in patients without liver disease. Patients who have liver test abnormalities prior to initiation of pioglitazone and glimepiride tablets or who are found to have abnormal liver tests while taking pioglitazone and glimepiride tablets should be managed as described under Warnings and Precautions [see Warnings and Precautions (5.5) and Clinical Pharmacology (12.3) ] . 2.2 Concomitant Use with an Insulin Secretagogue or Insulin If hypoglycemia occurs in a patient coadministered pioglitazone and glimepiride tablets and an insulin secretagogue, the dose of the insulin secretagogue should be reduced . If hypoglycemia occurs in a patient coadministered pioglitazone and glimepiride tablets 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. 2.3 Concomitant Use with Strong CYP2C8 Inhibitors Coadministration of pioglitazone and gemfibrozil, a strong CYP2C8 inhibitor, increases pioglitazone exposure approximately 3 fold. Therefore, the maximum recommended dose of pioglitazone is 15 mg daily when used in combination with gemfibrozil or other strong CYP2C8 inhibitors. If gemfibrozil or other CYP2C8 inhibitors need to co-administered, patients should switch to individual components of pioglitazone and glimepiride tablets because the minimum dose of pioglitazone in pioglitazone and glimepiride tablets exceeds 15 mg [see Drug Interactions (7.1) and Clinical Pharmacology (12.3) ]. 2.4 Concomitant Use with Colesevelam When colesevelam is coadministered with glimepiride, maximum plasma concentration and total exposure to glimepiride is reduced. Therefore, pioglitazone and glimepiride tablets should be administered at least four hours prior to colesevelam [see Drug Interactions (7.7) and Clinical Pharmacology (12.3) ] .

1 INDICATIONS AND USAGE Pioglitazone and glimepiride tablets are indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus who are already treated with a thiazolidinedione and sulfonylurea or who have inadequate glycemic control on a thiazolidinedione alone or a sulfonylurea alone [see Clinical Studies (14) ] .
