Glucagon is an antihypoglycemic agent and a gastrointestinal motility inhibitor. Glucagon is synthesized by solid phase peptide synthesis. The chemical structure of the glucagon is identical to human glucagon. Glucagon is a single-chain polypeptide that contains 29 amino acid residues and has a molecular weight of 3483 Daltons. The empirical formula is C 153 H 225 N 43 O 49 S. The primary sequence of glucagon is shown below. Crystalline glucagon is a white to off-white powder. It is relatively insoluble in water but is soluble at a pH of less than 3 or more than 9.5. Glucagon for injection, USP is a sterile lyophilized white to off white powder in a vial and a syringe of sterile diluent for intravenous, intramuscular, or subcutaneous use. The vial contains 1 mg of glucagon, 49 mg of lactose monohydrate. Hydrochloric acid may have been added during manufacture to adjust the pH of the glucagon to 2.5 to 3.0. One International Unit of glucagon is equivalent to 1 mg of glucagon. The 1-mL diluent syringe contains 12 mg of glycerin, 1 mg hydrochloric acid, and Water for Injection, at pH 1.8 to 2.2. emperical-formula
