Pharmacologic Category

  • Antidiabetic Agent, Dipeptidyl Peptidase 4 (DPP-4) Inhibitor

Pharmacology

Linagliptin inhibits dipeptidyl peptidase 4 (DPP-4) 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-4 enzyme.

Warnings/Precautions

Concerns related to adverse effects:

• Arthralgia: Severe and disabling arthralgia has been reported with DPP-4 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-4 inhibitor therapy resumed.

• Bullous pemphigoid: DPP-4 inhibitor use has been associated with development of bullous pemphigoid; cases have typically resolved with topical or systemic immunosuppressive therapy and discontinuation of DPP-4 inhibitor therapy. Advise patients to report development of blisters or erosions. Discontinue therapy if bullous pemphigoid is suspected and consider referral to a dermatologist.

• Hypersensitivity reactions: Rare hypersensitivity reactions (including anaphylaxis, angioedema, and exfoliative skin conditions) have been reported in patients treated with linagliptin; events have generally been noted within the first 3 months of therapy and may occur with the initial dose. Discontinue if signs/symptoms of hypersensitivity reactions occur. Use with caution if patient has experienced angioedema with other DPP-4 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.

Disease-related concerns:

• Bariatric surgery:

Altered absorption: Absorption may be altered given the anatomic and transit changes created by gastric bypass and sleeve gastrectomy surgery (Mechanick 2013; Melissas 2013).

Glucagon-like peptide-1 exposure and therapeutic efficacy: Closely monitor for signs and symptoms of pancreatitis; gastric bypass and sleeve gastrectomy may increase endogenous secretion of glucagon-like peptide-1 (Korner 2009; Peterli 2012). A single-dose, placebo-controlled study evaluated short-term therapy (4 weeks) with sitagliptin in gastric bypass patients having persistent or recurrent type 2 diabetes and found it to be well tolerated and provided a small but significant reduction in postprandial blood glucose (Shah 2018).

• Cardiovascular disease: In cardiovascular outcome trials of patients with type 2 diabetes and atherosclerotic cardiovascular disease, treatment with other DPP-4 inhibitors has been associated with HF. However, in a randomized, double-blind, placebo-controlled trial of patients with type 2 diabetes mellitus and high cardiovascular and renal risks, the occurrence of the primary composite cardiovascular outcome (cardiovascular death, nonfatal MI, nonfatal stroke) with linagliptin was found to be noninferior to placebo. In addition, the rate of hospitalization for HF did not differ from placebo, including in patients with preexisting HF. Median follow-up was 2.2 years (McGuire 2018; Rosenstock 2018). The ADA suggests DPP-4 inhibitors (except saxagliptin) may be considered in patients with HF (ADA 2019).

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.

Other warnings/precautions:

• Appropriate use: Not indicated for use in patients with type 1 diabetes mellitus (insulin dependent, IDDM) or with diabetic ketoacidosis (DKA).

• Patient education: Diabetes self-management education (DSME) is essential to maximize the effectiveness of therapy.

Monitoring Parameters

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 2019]), serum glucose; signs/symptoms of pancreatitis; signs/symptoms of heart failure

Pregnancy Considerations

Poorly controlled diabetes during pregnancy can be associated with an increased risk of adverse maternal and fetal outcomes, including diabetic ketoacidosis, preeclampsia, spontaneous abortion, preterm delivery, delivery complications, major birth defects, stillbirth, and macrosomia (ACOG 201 2013). 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 (ADA 2019; Blumer 2013).

Agents other than linagliptin are currently recommended to treat diabetes mellitus in pregnancy (ADA 2019).
