Liraglutide

Liraglutide is a first-generation GLP-1 receptor agonist primarily utilized for weight management and glycemic control in type 2 diabetes. Users typically administer the peptide via subcutaneous injection at a modal dose of 1.2 mg daily, though reported usage spans from 300 µg to 6 mg per day. While the substance is well-documented for its approved indications, the broader evidence base for exploratory uses remains thin, with many potential applications lacking published results. Reported side effects are infrequent, with nausea, gastrointestinal distress, sleep disturbances, and fluid retention surfacing only occasionally in community reports.

Research Evidence

Evidence shape

Liraglutide carries high-tier clinical evidence, supported by extensive research primarily focused on diabetes and obesity management. With 426 registered trials and 82 blinded studies, the literature base is robust, featuring 132 distinct sponsors and significant data on metabolic outcomes. While the clinical foundation for its primary indications is substantial, the research landscape also includes over 80 exploratory or thin indications, many of which are represented by single-trial long-tail studies that lack the scale or consistent results seen in its core therapeutic applications.

Regulatory safety notes

Warnings and precautions
  • • Acute Pancreatitis: Has been observed in patients treated with GLP-1 receptor agonists, including liraglutide injection. Discontinue if pancreatitis is suspected.
  • • Acute Gallbladder Disease: If cholelithiasis or cholecystitis are suspected, gallbladder studies are indicated.
  • • Hypoglycemia: Can occur in adults when liraglutide injection is used with an insulin secretagogue (e.g. a sulfonylurea) or insulin. The risk may be lowered by a reduction in the dose of concomitantly administered insulin secretagogues or insulin. In the pedia…
  • • Heart Rate Increase: Monitor heart rate at regular intervals.
  • • Acute Kidney Injury Due to Volume Depletion: Monitor renal function in patients reporting adverse reactions that could lead to volume depletion.
  • • Severe Gastrointestinal Adverse Reactions: Use has been associated with gastrointestinal adverse reactions, sometimes severe. Liraglutide injection is not recommended in patients with severe gastroparesis.
  • • Hypersensitivity Reactions: Postmarketing reports of serious hypersensitivity reactions (e.g., anaphylactic reactions and angioedema) . Discontinue liraglutide injection and other suspect medications and promptly seek medical advice.
  • • Pulmonary Aspiration During General Anesthesia or Deep Sedation : Has been reported in patients receiving GLP-1 receptor agonists undergoing elective surgeries or procedures. Instruct patients to inform healthcare providers of any planned surgeries or procedu…
Contraindications
  • • Patients with a personal or family history of medullary thyroid carcinoma (MTC) or
  • • patients with Multiple Endocrine Neoplasia syndrome type 2 (MEN 2) [see Warnings and Precautions (5.1) ] .
  • • Patients with a serious hypersensitivity reaction to liraglutide or to any of the excipients in liraglutide injection. Serious hypersensitivity reactions including anaphylactic reactions and angioedema have been reporte…
Drug interactions
  • • Liraglutide injection delays gastric emptying. May impact absorption of concomitantly administered oral medications. Use with caution. (7)
