Liraglutide (rDNA Origin)
Common Brand Name: Victoza, Saxenda*
Common Dosage Forms:
Solution for Injection (Victoza): Pre-filled, multi-dose 3 mL pens deliver doses of 0.6 mg, 1.2 mg, 1.8 mg (6 mg/mL).

FDA Indications/Dosages:
As an adjunct to diet and exercise to improve glycemic control in adults: One dose administered once daily by subcutaneous injection in the abdomen, thigh, or upper arm and independent of meals. Starting dose is 0.6 mg daily for one week and is intended to reduce gastrointestinal adverse effects during titration. After one week at 0.6 mg daily, increase the daily dose to 1.2 mg. If 1.2 mg does not produce sufficient glycemic control, the daily dose may be increased to 1.8 mg. Consider reducing the dose of concomitantly given sulfonylureas during initial titration.
Monitor: FBG, HbA1c, serum calcitonin
Pharmacology/Pharmacokinetics: Liraglutide is an acylated human glucagon-like peptide-1 (GLP-1) receptor agonist (97% similar to human GLP-1). In the presence of glucose, liraglutide increases intracellular cyclic AMP which results in the release of insulin from pancreatic beta cells. This insulin release decreases as glucose levels decrease. Liraglutide also decreases glucagon secretion in a glucose-dependent manner and delays gastric emptying. Unlike human GLP-1 which has a half-life of about 2 minutes, liraglutide has a half-life of 13 hours. Peak concentrations are reached 8-12 hours post dose. Plasma protein binding is extensive (98%). Liraglutide is endogenously metabolized similar to other proteins.
Drug Interactions: May decrease the plasma levels of digoxin and lisinopril. Additive effects may be seen when given with sulfonylureas.
Contraindications/Precautions: CONTRAINDICATED IN PATIENTS WITH A PERSONAL OR FAMILY HISTORY OF MEDULLARY THYROID CARCINOMA and in patients with Multiple Endocrine Neoplasia syndrome type 2. LIRAGLUTIDE INCREASES THE RISK OF MEDULLARY THYROID CARCINOMA, pancreatitis, hypoglycemia, and renal impairment. Pregnancy Category C.
Adverse Effects: Most common adverse effects are gastrointestinal in nature and include nausea (28%), diarrhea (17%), vomiting (11%), and constipation (10%). May also cause headache (9%). Rare but serious adverse effects include medullary thyroid carcinoma, pancreatitis, and renal impairment.
Patient Consultation:
Promptly report any signs of thyroid carcinoma (mass in the neck, dysphagia, dyspnea, or persistent hoarseness).
Promptly report any symptoms of pancreatitis (persistent severe abdominal pain with or without vomiting).
If a dose is missed, skip it and return to once daily dosing. Do not double doses. If more than 3 days have lapsed between doses, reinitiate with 0.5 mg daily.
