- Diabetes Mellitus, Non-Insulin-Dependent
Dosing
Diabetes Mellitus, Non-Insulin-Dependent Take once daily with a meal; recommended starting dose is 100 mg sitagliptin and 1000 mg metformin HCl extended-release once daily; maximum daily dose is 100 mg sitagliptin and 2000 mg metformin HCl; dose of sitagliptin component limited to 50 mg once daily if eGFR falls below 45 mL/min/1.73 m2; do not split, crush, or chew tablets.
Diabetes Mellitus, Non-Insulin-Dependent Administer U-100 or U-200 SC at meal start or within 20 minutes after starting a meal into abdomen, upper arm, thigh, or buttocks; U-100 also available via CSII insulin pump or IV infusion (under medical supervision, diluted to 1 unit/mL); individualize dose based on metabolic needs and glucose monitoring.
Contraindications
- Severe renal impairment (eGFR below 30 mL/min/1.73 m2)
- Acute or chronic metabolic acidosis, including diabetic ketoacidosis
- History of a serious hypersensitivity reaction to JANUMET XR, sitagliptin, or metformin, such as anaphylaxis or angioedema
- Episodes of hypoglycemia
- Hypersensitivity to insulin lispro-aabc or any excipient in LYUMJEV
Adverse Reactions
Most common (>=5%) Diarrhea, upper respiratory tract infection, headache (from sitagliptin and metformin coadministration studies); nasopharyngitis (sitagliptin monotherapy); hypoglycemia, diarrhea, nausea (extended-release metformin added to glyburide)
Serious Lactic acidosis, pancreatitis, heart failure, acute renal failure, vitamin B12 deficiency, hypoglycemia with insulin or insulin secretagogues, hypersensitivity reactions, severe and disabling arthralgia, bullous pemphigoid
Postmarketing Anaphylaxis, angioedema, rash, urticaria, cutaneous vasculitis, Stevens-Johnson syndrome, hepatic enzyme elevations, fatal and non-fatal hemorrhagic and necrotizing pancreatitis, worsening renal function including acute renal failure, tubulointerstitial nephritis, severe and disabling arthralgia, bullous pemphigoid, constipation, vomiting, myalgia, rhabdomyolysis, cholestatic and hepatocellular liver injury
Most common (>=5%) Nasopharyngitis, upper respiratory tract infection, infusion site reaction, infusion site pain
Serious Hypoglycemia (including severe), severe hypersensitivity reactions (anaphylaxis, angioedema, bronchospasm, hypotension, shock)
Postmarketing Localized cutaneous amyloidosis at injection site, hyperglycemia or hypoglycemia associated with injection into areas of localized cutaneous amyloidosis
Pharmacology
JANUMET XR combines sitagliptin, a selective DPP-4 inhibitor that slows inactivation of incretin hormones (GLP-1 and GIP) to increase insulin release and decrease glucagon in a glucose-dependent manner, and metformin, a biguanide that decreases hepatic glucose production, reduces intestinal glucose absorption, and improves peripheral insulin sensitivity without altering insulin secretion.
Rapid-acting human insulin analog that binds insulin receptors to stimulate peripheral glucose uptake in skeletal muscle and fat and inhibit hepatic glucose production, while also inhibiting lipolysis and proteolysis and enhancing protein synthesis.
