Liraglutide injection contains liraglutide, an analog of human GLP-1 and acts as a GLP-1 receptor agonist. The liraglutide is produced by a solid phase synthesis and is 97% homologous to native human GLP-1 by substituting arginine for lysine at position 34 and attaching a C-16 fatty acid (palmitic acid) with a glutamic acid spacer on the remaining lysine residue at position 26. The molecular formula of liraglutide is C 172 H 265 N 43 O 51 and the molecular weight is 3751.2 Daltons. The structural formula (Figure 1) is: Figure 1: Structural Formula of Liraglutide Liraglutide injection is a sterile, aqueous, clear, colorless solution for subcutaneous use. Each 1 mL of liraglutide injection solution contains 6 mg of liraglutide and the following inactive ingredients: disodium hydrogen phosphate dihydrate, 1.42 mg; phenol, 5.5 mg; propylene glycol, 14 mg; and water for injection. Liraglutide injection has a pH between 8.0 and 8.4, hydrochloric acid or sodium hydroxide may be added to adjust pH. Each prefilled pen contains a 3 mL solution of liraglutide injection equivalent to 18 mg liraglutide (free-base, anhydrous). Image
