Description
Combination of pioglitazone, a thiazolidinedione, and glimepiride, a second-generation sulfonylurea
Used in adults for the treatment of type 2 diabetes mellitus
Monitor patients for hypoglycemia, edema, weight gain, and heart failure
Indications
Indicated for management of type 2 diabetes mellitus as adjunct to diet and exercise
Indicated for type 2 diabetes mellitus in patients treated with combination of pioglitazone and a sulfonylurea, or patients not adequately controlled on a sulfonylurea alone, or who have initially responded to pioglitazone and require additional glycemic control Management of diabetes mellitus as adjunct to diet and exercise

Warnings
Increased risk of cardiovascular mortality
Edema; thiazolidinediones, which are peroxisome proliferator-activated receptor (PPAR) gamma agonists, can cause dose-related fluid retention, particularly when used in combination with insulin
Hemolytic anemia may occur with glucose 6-phosphate dehydrogenase (G6PD) deficiency when treated with sulfonylurea agents
Fluid retention may occur and can exacerbate or lead to congestive heart failure; combination use with insulin and use in congestive heart failure NYHA Class I and II may increase risk; monitor patients for signs and symptoms
Hypoglycemia may be severe. when insulin or an insulin secretagogue is used with pioglitazone, a lower insulin dose or insulin secretagogue dose may be needed to reduce risk of hypoglycemia
Postmarketing reports for glimepiride include anaphylaxis, angioedema, and Stevens-Johnson syndrome; promptly discontinue glimepiride, assess for other causes, institute appropriate monitoring and treatment, and initiate alternative treatment for diabetes
Postmarketing reports of hepatic failure, sometimes fatal; causality cannot be excluded; if liver injury detected, promptly interrupt therapy and assess patient for probable cause, then treat cause if possible, to resolution or stabilization; do not restart therapy if liver injury confirmed and no alternate etiology can be found
Dose-related edema may occur
Increased incidence of bone fracture reported
Macular edema reported; recommend regular eye exams in all patients with diabetes according to current standards of care with prompt evaluation for acute visual changes
No clinical studies establishing conclusive evidence of macrovascular risk reduction with glimepiride/pioglitazone or any other antidiabetic drug exist
Increase in weight gain possibly related to pioglitazone effects on fluid retention and fat accumulation
Pregnancy and Lactation
Limited data in pregnant women are not sufficient to determine a drug-associated risk for major birth defects or miscarriage; there are clinical considerations related to fetal and neonatal adverse reactions and drug discontinuation if glimepiride is used during pregnancy
There is no information regarding presence of pioglitazone or glimepiride in human milk, effects on breastfed infant, or on milk production; pioglitazone and glimepiride are present in rat milk; however, due to species-specific differences in lactation physiology, animal data may not reliably predict drug levels in human milk
