What is Gvoke?
Gvoke is a prescription medicine that is used to treat low blood sugar.
GVOKE contains glucagon, an antihypoglycemic agent used to treat severe hypoglycemia. Glucagon is a single chain containing 29 amino acid residues and has a molecular weight of 3483 and is identical to human glucagon. Glucagon is produced by solid phase synthesis with subsequent purification.
Its molecular formula is C 153H 225N 43O 49S with the following structure:
GVOKE is a clear, colorless to pale yellow, sterile solution for subcutaneous injection available in 0.5 mg per 0.1 mL or 1 mg per 0.2 mL auto-injector or pre-filled syringe, and in 1 mg per 0.2 mL vial and syringe kit.
GVOKE Auto-Injector (HypoPen) and GVOKE Pre-Filled Syringe
Each 0.2 mL of GVOKE contains 1 mg of glucagon, 11.1 mg of trehalose dihydrate NF, and 1.2 mg of 1N sulfuric acid NF, in dimethyl sulfoxide diluent.
Each 0.1 mL of GVOKE contains 0.5 mg of glucagon, 5.6 mg of trehalose dihydrate NF, and 0.6 mg of 1N sulfuric acid NF, in dimethyl sulfoxide diluent.
GVOKE Vial and Syringe Kit
Each 0.2 mL of GVOKE contains 1 mg of glucagon, 11.1 mg of trehalose dihydrate NF, 5.8 mg of mannitol USP, and 1.32 mg of 1N sulfuric acid NF, and NF in dimethyl sulfoxide diluent.
Mechanism of Action
Glucagon increases blood glucose concentration by activating hepatic glucagon receptors, thereby stimulating glycogen breakdown and release of glucose from the liver. Hepatic stores of glycogen are necessary for glucagon to produce an antihypoglycemic effect.
