Saxenda Vs. Trulicity: Drug Comparison

Saxenda^® (liraglutide) is an injectable medication used for chronic weight management in adults with obesity or overweight with at least one weight-related condition, such as hypertension, type 2 diabetes, or high cholesterol. It works by mimicking the hormone glucagon-like peptide-1 (GLP-1), which helps regulate appetite and food intake, leading to reduced caloric consumption and weight loss. Administered once daily, Saxenda is used in conjunction with a reduced-calorie diet and increased physical activity. Common side effects include nausea, diarrhea, and constipation, and it should be used with caution in patients with a history of pancreatitis​.

Trulicity^® (dulaglutide) is an injectable medication used to improve blood sugar control in adults and pediatric patients aged 10 years and older with type 2 diabetes, alongside diet and exercise. It acts as a glucagon-like peptide-1 (GLP-1) receptor agonist, enhancing insulin secretion, slowing gastric emptying, and reducing glucagon production. Additionally, Trulicity is indicated to reduce the risk of major adverse cardiovascular events, such as heart attack, stroke, and cardiovascular death in adults with type 2 diabetes who have established cardiovascular disease or multiple cardiovascular risk factors. Administered once weekly, Trulicity can be used alone or with other diabetes medications. Common side effects include gastrointestinal issues like nausea, diarrhea, and vomiting. It should be used cautiously in individuals with a history of pancreatitis​.

Glucagon-like peptide-1 (GLP-1) receptor agonist

Saxenda (liraglutide) is indicated:

• As an adjunct to a reduced-calorie diet and increased physical activity for chronic weight management in:

  • Adult patients with an initial body mass index (BMI) of:

    • 30 kg/m² or greater (obese), or

    • 27 kg/m² or greater (overweight) in the presence of at least one weight-related comorbid condition (e.g., hypertension, type 2 diabetes mellitus, or dyslipidemia)

  • Pediatric patients aged 12 years and older with:

    • Body weight above 60 kg and

An initial BMI corresponding to 30 kg/m² for adults (obese) by international cut-offs

Trulicity (dulaglutide) is indicated:

• As an adjunct to diet and exercise to improve glycemic control in adults and pediatric patients 10 years of age and older with type 2 diabetes mellitus.

• To reduce the risk of major adverse cardiovascular events in adults with type 2 diabetes mellitus who have established cardiovascular disease or multiple cardiovascular risk factors

• Typically taken as an injection once daily

• Comes in single-patient-use pens that deliver 0.6 mg, 1.2 mg, 1.8 mg, 2.4 mg, or 3 mg per injection

• Typically taken as an injection once weekly

• Comes in 0.75 mg, 1.5 mg, 3 mg, and 4.5 mg per 0.5 mL single-dose pens

• Vomiting

• Injection site reactions

• Headache

• Low blood sugar

• Indigestion

• Fatigue

• Dizziness

Most common adverse reactions (incidence ≥5%) are:

• Nausea

• Diarrhea

• Vomiting

• Abdominal pain

• Decreased appetite

• Personal or family history of medullary thyroid carcinoma or multiple endocrine neoplasia syndrome type 2

• Hypersensitivity to liraglutide or any excipients in Saxenda

• Drug interactions: Saxenda delays gastric emptying. May impact absorption of concomitantly administered oral medications

• Patients with a personal or family history of medullary thyroid carcinoma or in patients with multiple endocrine neoplasia syndrome type 2

• Patients with a serious hypersensitivity reaction to dulaglutide or any of the product components

• Drug interactions: Trulicity delays gastric emptying and has the potential to reduce the rate of absorption of concomitantly administered oral medications

• Thyroid C-cell tumors

• Acute pancreatitis

• Acute gallbladder disease

• Low blood sugar: Can occur in adults when Saxenda is used with an insulin secretagogue (e.g., a sulfonylurea) or insulin

• Heart rate increase

• Renal impairment

• Hypersensitivity reactions

• Suicidal behavior and ideation

• Thyroid C-cell tumors

• Pancreatitis

• Low blood sugar: Concomitant use with an insulin secretagogue or insulin may increase the risk of low blood sugar, including severe low blood sugar

• Hypersensitivity reactions

• Acute kidney injury

• Severe gastrointestinal disease

• Diabetic retinopathy complications

• Acute gallbladder disease

• Pregnancy: Should be used during pregnancy only if the potential benefit justifies the potential risk to fetus

WARNING: RISK OF THYROID C-CELL TUMORS

Liraglutide causes thyroid C-cell tumors at clinically relevant exposures in both genders of rats and mice. It is unknown whether Saxenda causes thyroid C-cell tumors, including medullary thyroid carcinoma (MTC), in humans, as the human relevance of liraglutide-induced rodent thyroid C-cell tumors has not been determined.

Saxenda is contraindicated in patients with a personal or family history of MTC or in patients with multiple endocrine neoplasia syndrome type 2 (MEN 2). Counsel patients regarding the potential risk of MTC and the symptoms of thyroid tumors.

WARNING: RISK OF THYROID C-CELL TUMORS

Dulaglutide causes thyroid C-cell tumors in rats. It is unknown whether Trulicity causes thyroid C-cell tumors, including medullary thyroid carcinoma (MTC), in humans as the human relevance of dulaglutide-induced rodent thyroid C-cell tumors has not been determined.

Trulicity is 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 the potential risk of MTC and symptoms of thyroid tumors.
