Drug class: Incretin Mimetics

Medically reviewed by Drugs.com on Oct 16, 2023. Written by ASHP.

Warning

    Risk of Thyroid C-Cell Tumors
  • Liraglutide causes dose-dependent and treatment duration-dependent thyroid C-cell tumors (adenomas and/or carcinomas) at clinically relevant exposures in both genders of rats and mice.

  • Unknown whether liraglutide causes thyroid C-cell tumors, including medullary thyroid carcinoma (MTC), in humans, as relevance to humans of such tumors in rodents has not been determined.

  • Contraindicated in patients with a personal or family history of MTC and in patients with multiple endocrine neoplasia syndrome type 2 (MEN 2).

    Counsel patients regarding potential risk of MTC and inform them about symptoms of thyroid tumors.

    Routine monitoring of serum calcitonin or use of thyroid ultrasound of uncertain value for early detection of MTC in patients receiving liraglutide.

Introduction

Antidiabetic and antiobesity agent; acylated glucagon-like peptide-1 (GLP-1) agonist (incretin mimetic).

Uses for Liraglutide

Type 2 Diabetes Mellitus

Glycemic Control

Used as an adjunct to diet and exercise to improve glycemic control in adults and pediatric patients ≥10 years of age with type 2 diabetes mellitus.

Has been used in combination with metformin, a sulfonylurea, or the combination of metformin and a sulfonylurea as an adjunct to diet and exercise for the management of type 2 diabetes mellitus.

Various preparations of liraglutide are available; Victoza injection and the fixed-combination injection containing liraglutide and insulin degludec (Xultophy) are specifically FDA-labeled for use in the management of diabetes mellitus.

Current guidelines for the treatment of type 2 diabetes mellitus generally recommend metformin as first-line therapy in addition to lifestyle modifications in patients with recent-onset type 2 diabetes mellitus or mild hyperglycemia because of its well-established safety and efficacy (i.e., beneficial effects on glycosylated hemoglobin [hemoglobin A1c; HbA1c], weight, and cardiovascular mortality).

In patients with metformin contraindications or intolerance (e.g., risk of lactic acidosis, GI intolerance) or in selected other patients, some experts suggest that initial therapy with a drug from another class of antidiabetic agents (e.g., a GLP-1 receptor agonist, sodium-glucose cotransporter 2 [SGLT2] inhibitor, dipeptidyl peptidase-4 [DPP-4] inhibitor, sulfonylurea, thiazolidinedione, basal insulin) may be acceptable based on patient factors.

May need to initiate therapy with 2 agents (e.g., metformin plus another drug) in patients with high initial HbA1c (>7.5% or ≥1.5% above target). In such patients with metformin intolerance, some experts suggest initiation of therapy with 2 drugs from other antidiabetic drug classes with complementary mechanisms of action.

Consider early initiation of combination therapy for the treatment of type 2 diabetes mellitus to extend the time to treatment failure and more rapidly attain glycemic goals.

For patients with inadequate glycemic control on metformin monotherapy, consider patient comorbidities (e.g., atherosclerotic cardiovascular disease [ASCVD], established kidney disease, heart failure), hypoglycemia risk, impact on weight, cost, risk of adverse effects, and patient preferences when selecting additional antidiabetic agents for combination therapy.

Consider early introduction of insulin for severe hyperglycemia (e.g., blood glucose of ≥300 mg/dL or HbA1c >9–10%), especially if accompanied by catabolic manifestations (e.g., weight loss, hypertriglyceridemia, ketosis) or symptoms of hyperglycemia.

Experts recommend that patients with type 2 diabetes mellitus who have established (or are at a high risk for) ASCVD, established kidney disease, or heart failure receive a GLP-1 receptor agonist or SGLT2 inhibitor with demonstrated cardiovascular disease benefit. In patients with these comorbidities, consider GLP-1 receptor agonist or SGLT2 inhibitor therapy independently of patient's HbA1c.

In patients with type 2 diabetes mellitus and CKD, consider a GLP-1 receptor agonist or SGLT2 inhibitor shown to reduce the risk of CKD progression, cardiovascular events, or both, in addition to metformin therapy or in those in whom metformin cannot be used.

In patients on metformin monotherapy without established ASCVD or indicators of high ASCVD risk, heart failure, or CKD, base decision regarding addition of other antidiabetic agents on avoidance of adverse effects, cost, and individual patient factors.

Liraglutide or fixed combination of insulin degludec and liraglutide (Xultophy) not indicated for the treatment of type 1 diabetes mellitus.

Reduction in Risk of Major Adverse Cardiovascular Events

Used to reduce the risk of major adverse cardiovascular events (i.e., cardiovascular death, nonfatal MI, nonfatal stroke) in adults with type 2 diabetes mellitus and established cardiovascular disease.

Manufacturer states that effects on cardiovascular morbidity and mortality not established in patients receiving liraglutide for management of obesity.

Beneficial Effects on Renal Function

Some experts suggest that use of a GLP-1 receptor agonist may reduce risk of progression of albuminuria, cardiovascular events, or both [off-label] in patients with type 2 diabetes mellitus and CKD who are at increased risk for cardiovascular events. Reduced risk of new or worsening nephropathy [off-label] demonstrated with liraglutide in a clinical study.

Chronic Weight Management

Used as an adjunct to a reduced-calorie diet and increased physical activity for the long-term management of body weight.

Indicated for use in adults who are obese (pretreatment BMI ≥30 kg/m2) or who are overweight (pretreatment BMI ≥27 kg/m2) and have at least one weight-related condition (e.g., hypertension, type 2 diabetes mellitus, dyslipidemia).

Indicated for use in pediatric patients ≥12 years of age with a body weight >60 kg and an initial BMI corresponding to 30 kg/m2 for adults (obese) by international cut-offs.

Various preparations of liraglutide are available; Saxenda injection is specifically FDA-labeled for use in chronic weight management.

Manufacturer states that Saxenda preparation is not intended for use in the treatment of type 2 diabetes mellitus. In addition, Saxenda should not be used in combination with any other GLP-1 receptor agonist or with insulin.

Safety and efficacy in combination with other weight-loss products (prescription or OTC drugs, dietary or herbal supplements) not established.

Safety and efficacy not established in patients with a history of pancreatitis.

Safety and efficacy in combination with insulin not established in the management of obesity; do not use with insulin for obesity management.

There is some evidence suggesting once-weekly sub-Q semaglutide injections produce greater weight loss than once-daily sub-Q liraglutide injections.

Clinical practice guidelines recommend that patients with excess body weight and associated health risks be treated for obesity. Essential component of therapy is a comprehensive lifestyle intervention; may consider pharmacologic therapy as an adjunct in patients who fail to achieve or sustain clinically meaningful weight loss (generally defined as loss of >4–5% of total body weight) with behavioral modification alone. Evaluate response to drug therapy after 3–4 months; if clinically meaningful weight loss not achieved, consider new treatment plan because patient is likely not responding to the drug.

Liraglutide Dosage and Administration

General

Patient Monitoring

Administration

Administer liraglutide or the fixed combination of insulin degludec and liraglutide (insulin degludec/liraglutide) by sub-Q injection once daily using a prefilled injection pen; do not administer IV or IM.

Rotate injection sites within the same region to reduce the risk of cutaneous amyloidosis.

If a dose of liraglutide or insulin degludec/liraglutide is missed, resume the regular schedule with the next scheduled dose; do not take an extra dose or increase the dose to replace a missed dose. If >3 days have elapsed since last dose, restart liraglutide or insulin degludec/liraglutide at initial dosage and retitrate.

Administer liraglutide and insulin as separate injections in patients receiving both drugs for diabetes mellitus; do not mix insulin and liraglutide. For patients receiving liraglutide in whom it is appropriate to add therapy with insulin degludec, these drugs are commercially available in fixed combination as Xultophy. May inject liraglutide and insulin in the same body regions; however, do not administer injections adjacent to each other.

Sub-Q Administration

Liraglutide: Administer once daily at any time of day without regard to meals.

Fixed combination of insulin degludec and liraglutide: Administer at the same time each day without regard to meals.

Administer liraglutide or the fixed combination of insulin degludec and liraglutide into abdomen, thigh, or upper arm.

Dosage

Pediatric Patients

Type 2 Diabetes Mellitus
Liraglutide
Sub-Q

Children and adolescents ≥10 years of age: Initially, 0.6 mg daily. After ≥1 week, may increase dosage in 0.6 mg increments if additional glycemic control required. The maximum recommended dosage is 1.8 mg once daily.

If a dose is missed and more than 3 days have elapsed since the last dose, reinitiate at 0.6-mg dosage to minimize adverse GI effects and titrate dosage at the discretion of the clinician.

Chronic Weight Management
Sub-Q

Pediatric patient ≥12 years of age: Initially, 0.6 mg daily.

Increase daily dosage by 0.6 mg at weekly intervals to maintenance dosage of 3 mg daily.

If pediatric patients do not tolerate an increased dose during dose escalation, the dose may be lowered to the previous level. Dose escalation for pediatric patients may take up to 8 weeks.

In pediatric patients who do not tolerate dosage of 3 mg daily, may reduce maintenance dosage to 2.4 mg daily. Discontinue therapy if the patient cannot tolerate the 2.4 mg dose.

Evaluate change in BMI in pediatric patients after 12 weeks on the maintenance liraglutide dosage and discontinue treatment if the patient has not had a reduction in BMI of ≥1% from baseline, since it is unlikely that the patient will achieve and sustain clinically meaningful weight loss with continued treatment.

Adults

Type 2 Diabetes Mellitus
Liraglutide
Sub-Q

Initially, 0.6 mg daily. The 0.6-mg dosage is not effective for glycemic control in adults; intended only as a starting dose to reduce GI intolerance.

After 1 week, increase dosage to 1.2 mg daily. If clinical response is inadequate, may increase dosage to 1.8 mg daily after ≥1 week of treatment with 1.2-mg daily dosage.

If a dose is missed and more than 3 days have elapsed since the last dose, reinitiate at 0.6-mg dosage to minimize adverse GI effects and titrate dosage at the discretion of the clinician.

Insulin Degludec/Liraglutide Fixed-combination Therapy
Sub-Q

Dosage of the fixed combination of insulin degludec and liraglutide (nsulin degludec/liraglutide; Xultophy 100/3.6) is expressed in terms of units of insulin degludec on the dose counter display of the Xultophy injection pen; each dosage unit delivers 1 unit of insulin degludec and 0.036 mg of liraglutide.

Patients naive to basal insulin or GLP-1 receptor agonist: Initially, 10 units (10 units of insulin degludec with 0.36 mg of liraglutide) once daily.

Patients currently receiving basal insulin or a GLP-1 receptor agonist: Discontinue therapy with basal insulin GLP-1 receptor agonist. Initially, 16 units (16 units of insulin degludec with 0.58 mg of liraglutide) once daily.

Dosage of insulin degludec/liraglutide may be increased or decreased by 2 units (of insulin degludec) every 3–4 days as needed. May be increased to a maximum daily dosage of 50 units (50 units of insulin degludec with 1.8 mg of liraglutide).

If a dose is missed and more than 3 days have elapsed since the last dose, reinitiate at starting dose to minimize adverse GI effects due to liraglutide component.

Chronic Weight Management
Sub-Q

Initially, 0.6 mg daily.

Increase daily dosage by 0.6 mg at weekly intervals to maintenance dosage of 3 mg daily.

If dosage increase not tolerated (e.g., adverse GI effects), may delay dosage escalation for approximately 1 week. If 3-mg daily dosage not tolerated, discontinue therapy; efficacy not established at dosages <3 mg daily.

If a dose is missed and more than 3 days have elapsed since the last dose, reinitiate at 0.6-mg dosage to minimize adverse GI effects; retitrate to maintenance dosage of 3 mg once daily.

Evaluate body weight 16 weeks after initiating liraglutide in adults. Discontinue treatment in patients who do not experience a meaningful reduction in weight (≥4% of baseline body weight) after 16 weeks; such patients are unlikely to achieve and sustain meaningful weight loss with continued liraglutide therapy.

Special Populations

Liraglutide: No special population dosage recommendations. Use caution when initiating liraglutide or escalating dosage in patients with renal impairment.

Fixed combination of insulin degludec and liraglutide: Data lacking on use in patients with hepatic impairment. Limited experience with use of the fixed combination in patients with mild or moderate renal impairment; intensify glucose monitoring and individualize dosage as required.

Cautions for Liraglutide

Contraindications

Warnings/Precautions

Warnings

Risk of Thyroid C-Cell Tumors

Dose-dependent and treatment-duration-dependent thyroid C-cell tumors found at clinically relevant exposures in rats and mice. Cases of MTC reported in patients receiving liraglutide during postmarketing experience; data insufficient to establish or exclude a causal relationship between MTC and liraglutide use in humans. Unknown whether liraglutide causes thyroid C-cell tumors, including MTC, in humans; relevance to humans could not be ruled out by clinical or nonclinical studies. Therefore, do not use as first-line treatment for diabetes mellitus until additional studies completed.

Very elevated serum calcitonin values may suggest MTC; such values generally exceed 50 ng/L in patients with MTC. Uncertain value of routine monitoring of serum calcitonin or thyroid ultrasound examinations; further evaluate patients if serum calcitonin is elevated or thyroid nodules noted on physical examination or neck imaging.

To specifically evaluate the risk of MTC, manufacturer is required to establish a cancer registry to monitor the rate of this type of cancer in the US over a period of 15 years.

Sensitivity Reactions

Hypersensitivity Reactions

Serious hypersensitivity reactions (anaphylaxis, angioedema) reported. Asthma, bronchial hyperreactivity, bronchospasm, oropharyngeal swelling, facial swelling, pharyngeal edema, and type IV hypersensitivity reactions also reported. Anaphylactic reactions with additional symptoms (e.g., hypotension, palpitations, dyspnea, edema) reported; may be potentially life-threatening.

Discontinue liraglutide-containing therapy and other suspect drugs and promptly seek medical advice if hypersensitivity reaction occurs. Use with caution in patients with a history of angioedema with another GLP-1 receptor agonist.

Other Warnings and Precautions

Use of Fixed Combinations

When liraglutide is used in fixed combination with insulin degludec or other drugs, consider the cautions, precautions, contraindications, and interactions associated with the concomitant agent(s) in addition to those associated with liraglutide.

Risks During General Anesthesia and Deep Sedation

GLP-1 agonists are associated with adverse GI effects such as nausea, vomiting, and delayed gastric emptying.

Delayed gastric emptying from GLP-1 agonists can increase the risk of regurgitation and pulmonary aspiration of gastric contents during general anesthesia and deep sedation.

The American Society of Anesthesiologists (ASA) Task Force on Preoperative Fasting has issued a consensus-based guidance for management of GLP-1 receptor agonists prior to elective surgery. The task force suggests that for patients on daily GLP-1 agonist dosing (irrespective of indication, dose, or type of surgery), consider holding the drug on the day of procedure/surgery. For patients on weekly dosing (irrespective of indication, dose, or type of surgery), consider holding the GLP-1 agonist a week prior to procedure/surgery. If GLP-1 agonists prescribed for diabetes management are held for longer than the dosing schedule, consider consulting an endocrinologist for bridging the antidiabetic therapy to avoid hyperglycemia.

For patients requiring urgent or emergent procedures, the task force states to proceed and treat the patient as ‘full stomach’ and manage accordingly.

Pancreatitis and Pancreatic Precancerous Changes

Acute pancreatitis, including fatal and nonfatal hemorrhagic or necrotizing pancreatitis, reported during postmarketing experience. Pancreatitis also reported during clinical trials.

Observe patients carefully for manifestations of pancreatitis after drug initiation and dosage increases. If pancreatitis is suspected, promptly discontinue liraglutide and initiate appropriate management. If pancreatitis is confirmed, do not restart liraglutide.

Evaluated in a limited number of adults with a history of pancreatitis; not known if patients with a history of pancreatitis are at increased risk of pancreatitis while taking liraglutide.

Acute Gallbladder Disease

May increase the risk of acute gallbladder disease. Cholelithiasis and cholecystitis reported in GLP-1 receptor agonist clinical trials; most cases required cholecystectomy.

Although substantial or rapid weight loss can increase risk of cholelithiasis, the incidence of acute gallbladder disease was greater with liraglutide than with placebo in obesity clinical trials, even after accounting for the degree of weight loss. If cholelithiasis suspected, gallbladder studies and appropriate clinical follow-up are recommended.

Sharing of Injection Pens

Do not share injection pens containing liraglutide (Victoza, Saxenda) or the fixed combination of liraglutide and insulin degludec (Xultophy) among patients, even if the needle has been changed; sharing poses risk for transmission of blood-borne pathogens.

Hypoglycemia

Patients receiving liraglutide in combination with an insulin secretagogue (e.g., a sulfonylurea) or insulin may have an increased risk of hypoglycemia; reduction in sulfonylurea or insulin dosage may be necessary. Risk of hypoglycemia higher with liraglutide in pediatric patients ≥10 years of age with type 2 diabetes mellitus regardless of concomitant antidiabetic therapy.

Hypoglycemia also reported in liraglutide-treated pediatric patients receiving the drug for chronic weight management.

Manufacturer states that insulin should not be used concomitantly in patients receiving liraglutide for chronic weight management.

Monitor blood glucose parameters prior to starting and during treatment in patients with type 2 diabetes mellitus receiving liraglutide for chronic weight management. If needed, adjust dosage of coadministered antidiabetic drugs based on results of glucose monitoring and risk of hypoglycemia.

Monitor patients with type 2 diabetes mellitus for an increase in blood glucose when liraglutide is discontinued.

Elevated Heart Rate

Increases in heart rate observed with liraglutide therapy for type 2 diabetes mellitus or obesity management. Resting heart rate >100 bpm reported. Tachycardia reported in 0.6% of patients receiving liraglutide for management of obesity versus 0.1% of placebo recipients. Clinical importance of elevated heart rate unknown, especially in patients with cardiovascular or cerebrovascular disease who had limited exposure to liraglutide in obesity clinical trials.

Monitor heart rate regularly; if sustained increase in resting heart rate occurs during therapy, discontinue liraglutide.

Renal Effects

Acute renal failure and worsening of chronic renal failure (sometimes requiring hemodialysis) reported with GLP-1 receptor agonists, including liraglutide, during postmarketing experience. Some patients did not have known underlying renal disease. Other factors (nausea, vomiting, diarrhea, or dehydration) were present in most patients. Some patients received liraglutide in combination with one or more agents known to affect renal function or hydration status.

Not found to be directly nephrotoxic in preclinical or clinical studies.

Renal effects usually reversible with supportive treatment and discontinuance of potentially causative agents, including liraglutide. Use caution when initiating liraglutide or escalating dosage in patients with renal impairment.

Suicidality

Suicidal ideation observed in clinical trials for weight management; suicide attempt reported in one patient.

Monitor patients receiving liraglutide for emergence or worsening of depression, suicidal thoughts or behavior (suicidality), and/or any unusual changes in mood or behavior. Discontinue in patients who experience suicidal thoughts or behaviors.

Avoid use in patients with a history of suicidal attempts or active suicidal ideation.

Immunogenicity

Development of antibodies to liraglutide reported. Development of cross-reactive antibodies to native GLP-1 peptide has occurred; potential for clinically important neutralization of native GLP-1 unknown. Antibody formation has not been associated with reduced efficacy of liraglutide or an increase in adverse events potentially related to immunogenicity (e.g., urticaria, angioedema). However, presence of antibodies has been associated with a higher incidence of injection site reactions and reports of low blood glucose, usually mild and resolving with continued treatment.

Specific Populations

Pregnancy

Data are lacking on the use of liraglutide (Victoza) in pregnant women. Reproduction studies in rats using liraglutide have shown teratogenic effects. Studies in rabbits have shown reduced growth and major abnormalities. Use liraglutide for the management of diabetes mellitus during pregnancy only when potential benefits justify possible risks to fetus.

Weight loss offers no potential benefit to pregnant women and may result in fetal harm. Manufacturer states that liraglutide is contraindicated for the management of obesity in pregnant women. Discontinue liraglutide for obesity management if patient is or plans to become pregnant.

Lactation

Liraglutide is distributed into milk in rats; not known whether distributed into milk in humans. Discontinue nursing or the drug, taking into account the importance of the drug to the woman.

Pediatric Use

Safety and efficacy of liraglutide for the management of type 2 diabetes mellitus not established in children or adolescents <10 years of age.

Safety and efficacy of liraglutide for chronic weight management not established, and use not recommended, in children or adolescents <18 years of age.

Safety and efficacy of the fixed combination of insulin degludec and liraglutide not established in pediatric patients.

Geriatric Use

No substantial differences in safety and efficacy relative to younger adults, but increased sensitivity cannot be ruled out.

Hepatic Impairment

Limited experience in patients with hepatic impairment; use caution.

Renal Impairment

In a clinical study of 26 weeks' duration, patients with moderate renal impairment (eGFR 30–59 mL/minute per 1.73 m2) who received liraglutide 1.8 mg once daily had no worsening of renal function. Experience with liraglutide in patients with renal impairment or end-stage renal disease is limited. Use caution when initiating or escalating doses of liraglutide in patients with renal impairment.

Patients with Gastroparesis

Slows gastric emptying and potentially may affect absorption of concomitantly administered oral drugs. Has not been studied in patients with preexisting gastroparesis.

Common Adverse Effects
