- Antidiabetic Agent, Dipeptidyl Peptidase 4 (DPP-4) Inhibitor
Linagliptin inhibits dipeptidyl peptidase IV (DPP-IV) enzyme resulting in prolonged active incretin levels. Incretin hormones (eg, glucagon-like peptide-1 [GLP-1] and glucose-dependent insulinotropic polypeptide [GIP]) regulate glucose homeostasis by increasing insulin synthesis and release from pancreatic beta cells and decreasing glucagon secretion from pancreatic alpha cells. Decreased glucagon secretion results in decreased hepatic glucose production. Under normal physiologic circumstances, incretin hormones are released by the intestine throughout the day and levels are increased in response to a meal; incretin hormones are rapidly inactivated by the DPP-IV enzyme.
Not extensively metabolized
80% feces unchanged; 5% urine unchanged
Time to Peak
Effective (therapeutic): ~12 hours; Terminal (DPP-IV saturable binding): >100 hours
70% to 80%; concentration dependent
Special Populations: Renal Function Impairment
Exposure of linagliptin is increased in moderate and severe renal impairment, but renal clearance was below 5% and 7% of the administered dose, respectively. No dosage adjustment is required.
Special Populations: Hepatic Function Impairment
Mean AUC and Cmax of linagliptin decreased in patients with mild or moderate hepatic impairment, and Cmax decreased in patients with severe hepatic impairment. However, no dosage adjustment is necessary.
Use: Labeled Indications
Type 2 diabetes mellitus: As an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes (noninsulin dependent, NIDDM) as monotherapy or in combination with other antidiabetic agents
Hypersensitivity (eg, anaphylaxis, angioedema, exfoliative skin conditions, urticaria, or bronchial hyperreactivity) to linagliptin or any component of the formulation
Canadian labeling: Additional contraindications: Use in type 1 diabetes mellitus or diabetic ketoacidosis
Type 2 diabetes: Oral: 5 mg once daily
Concomitant use with insulin and/or insulin secretagogues (eg, sulfonylureas): Reduced dose of insulin and/or insulin secretagogues may be needed.
Refer to adult dosing.
Dosing: Renal Impairment
No dosage adjustment necessary.
Dosing: Hepatic Impairment
No dosage adjustment necessary. Note: Canadian labeling does not recommend use in severe hepatic impairment.

<1% (Limited to important or life-threatening): Acute pancreatitis, severe arthralgia (FDA Safety Alert, Aug 28, 2015), severe hypersensitivity, stomatitis
Concerns related to adverse effects:
• Arthralgia: Severe and disabling arthralgia has been reported with DPP-IV inhibitor use; onset may occur within one day to years after treatment initiation and may resolve with discontinuation of therapy. Some patients may experience a recurrence of symptoms if DPP-IV inhibitor therapy resumed.
• Hypersensitivity reactions: Rare hypersensitivity reactions (including anaphylaxis, angioedema, and exfoliative skin conditions) have been reported in patients treated with linagliptin; discontinue if signs/symptoms of hypersensitivity reactions occur. Events have generally been noted within the first 3 months of therapy, and may occur with the initial dose. Use with caution if patient has experienced angioedema with other DPP-IV inhibitor use.
• Pancreatitis: Cases of acute pancreatitis, including fatalities, have been reported with use. Monitor for signs/symptoms of pancreatitis; discontinue use immediately if pancreatitis is suspected and initiate appropriate management. Use with caution in patients with a history of pancreatitis as it is not known if this population is at greater risk.
Concurrent drug therapy issues:
• Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information.
• Diabetes mellitus (type 1): Not indicated for use in patients with type 1 diabetes mellitus (insulin dependent, IDDM) due to lack of efficacy in this patient population.
• Diabetic ketoacidosis: Not indicated for the treatment of diabetic ketoacidosis (DKA) due to lack of efficacy in this patient population.
• Heart failure: Clinical trials included only a limited number of patients with heart failure (HF). No specific recommendations regarding this population are provided in the approved U.S. labeling (Canadian labeling recommends against use in this population).
• Patient education: Diabetes self-management education (DSME) is essential to maximize the effectiveness of therapy.
HbA1c (at least twice yearly in patients who have stable glycemic control and are meeting treatment goals; quarterly in patients not meeting treatment goals or with therapy change [ADA 2016a]), serum glucose; signs/symptoms of pancreatitis
Pregnancy Risk Factor
Adverse events were not observed in animal reproduction studies, except with doses that were also maternally toxic.
In women with diabetes, maternal hyperglycemia can be associated with congenital malformations as well as adverse effects in the fetus, neonate, and the mother (ACOG 2005; ADA 2015; Kitzmiller 2008; Metzger 2007). To prevent adverse outcomes, prior to conception and throughout pregnancy maternal blood glucose and HbA1c should be kept as close to target goals as possible but without causing significant hypoglycemia (ACOG 2013; ADA 2015; Blumer 2013; Kitzmiller 2008). Prior to pregnancy, effective contraception should be used until glycemic control is achieved (Kitzmiller 2008). Other agents are currently recommended to treat diabetes in pregnant women (ACOG 2013; Blumer 2013).
• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
• Patient may experience pharyngitis, rhinitis, rhinorrhea, cough, or diarrhea. Have patient report immediately to prescriber signs of low blood sugar (dizziness, headache, fatigue, feeling weak, shaking, a fast heartbeat, confusion, hunger, or sweating), signs of pancreatitis (severe abdominal pain, severe back pain, severe nausea, or vomiting), eczema, dysphagia, or severe joint pain (HCAHPS).
• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
