Renal dysfunction, e.g., serum creatinine >1.5 mg/dL [males], >1.4 mg/dL [females] or abnormal creatinine clearance. Metabolic acidosis, including diabetic ketoacidosis. History of a serious hypersensitivity reaction (e.g., anaphylaxis or angioedema) to Sitagliptin + Metformin or to one of its components.

Precautions

Not for use in type 1 DM or treatment of ketoacidosis. Discontinue use if pancreatitis is suspected. Renal & hepatic impairment. Sulfonylurea- or insulin-induced hypoglycemia, risk of lactic acidosis, hypoxic states, surgical procedures, alcohol intake, decreased vit B12 absorption, loss of glycemic control. Pregnancy. Elderly. Childn <18 yr. Lactation: not known if crosses into breast milk, use caution Pregnancy Categories

Pregnancy-Lactation

Pregnancy There is pregnancy exposure registry that monitors pregnancy outcomes in women exposed to drug during pregnancy; health care providers are encouraged to report any prenatal exposure to drug by calling the Pregnancy Registry at 1-800-986-8999 Limited available data in pregnant women are not sufficient to inform a drug- associated risk for major birth defects and miscarriage; published studies with metformin use during pregnancy have not reported a clear association with metformin and major birth defect or miscarriage risk; there are risks to mother and fetus associated with poorly controlled diabetes in pregnancy Poorly controlled diabetes in pregnancy increases maternal risk for diabetic ketoacidosis, pre-eclampsia, spontaneous abortions, preterm delivery, still birth, and delivery complications; poorly controlled diabetes increases fetal risk for major birth defects, still birth, and macrosomia related morbidity Discuss potential for unintended pregnancy with premenopausal women as therapy with metformin may result in ovulation in some anovulatory women Lactation There is no information regarding presence in human milk, effects on breastfed infant, or on milk production; limited published studies report that metformin is present in human milk; there are no reports of adverse effects on breastfed infants exposed to metformin; there is no information on effects of metformin on milk production; sitagliptin is present in rat milk and therefore possibly present in human milk; developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for therapy and any potential adverse effects on breastfed infant from drug or from underlying maternal condition

Interactions

Additive effect w/ sulfonylureas. Thiazide diuretics, corticosteroids, phenothiazines, OC, sympathomimetics, niacin, Ca channel blockers and isoniazid may exacerbate loss of glycaemic control. ACE inhibitors may reduce fasting blood glucose concentrations. May increase serum level w/ cimetidine. Potentially Fatal: Concurrent use w/ iodinated contrast agents may increase the risk of metformin-induced lactic acidosis.

Adverse Effects

Side effects of Metformin Hydrochloride + Sitagliptin : 1-10% Abdominal pain (2.2%), Diarrhea (2.4%), Hypoglycemia (2.1%), Nausea (1.3%), Vomiting (1.1%) Frequency Not Defined Exfoliative disorder of skin of scalp, Stevens-Johnson syndrome, Lactic acidosis (rare ), Anaphylaxis/hypersensitivity reaction, Rhabdomyolysis, Acute renal failure, Angioedema

Mechanism of Action

Sitagliptin: Dipeptidyl peptidase 4 (DPP-4) inhibitor, thereby increasing and prolonging incretin hormone activity which are inactivated by DPP-4 enzyme. Incretins increase insulin release and synthesis from pancreatic beta cells and reduce glucagon secretion pancreatic alpha cells. Metformin: Biguanide; acts by decreasing endogenous hepatic glucose production, decreases intestinal absorption of glucose, and improves insulin sensitivity by increasing peripheral glucose uptake and utilization; improves glucose tolerance and lowers both basal and postprandial plasma glucose .
