Hyaluronidase is an endoglycosidase. It is a preparation of purified bovine testicular hyaluronidase, a protein enzyme. Hyaluronidase is composed of two major glycosylated forms, α and β. The exact chemical structure of this enzyme is unknown. Amphadase ® (hyaluronidase injection) is supplied as a sterile, clear and colorless, ready for use 1 mL solution in a single-dose vial for infiltration use, for interstitial use, for intramuscular use, for peribulbar use, for soft tissue use, or for subcutaneous use. Each mL contains 150 USP units of hyaluronidase with calcium chloride (0.4 mg), edetate disodium (1.0 mg), monobasic sodium phosphate (1.7 mg), sodium chloride (8.5 mg), not more than 0.1 mg thimerosal (mercury derivative), and Water for Injection, USP.
