hyaluronidase - Generic Medications

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. Sodium hydroxide may be added to adjust pH. Amphadase ® has an approximate pH of 6.8 and an osmolality of 295 to 355 mOsm.

HYLENEX recombinant is a purified preparation of the enzyme recombinant human hyaluronidase. HYLENEX recombinant is produced by genetically engineered Chinese Hamster Ovary (CHO) cells containing a DNA plasmid encoding for a soluble fragment of human hyaluronidase (PH20). The purified hyaluronidase glycoprotein contains 447 amino acids with an approximate molecular weight of 61,000 Daltons. HYLENEX recombinant is supplied as a sterile, clear, colorless, nonpreserved, ready-for-use solution. Each mL contains 150 USP units of recombinant human hyaluronidase with 8.5 mg sodium chloride, 1.4 mg dibasic sodium phosphate, 1 mg albumin human, 1.5 mg L-methionine, 0.2 mg polysorbate 80, and hydrochloric acid and sodium hydroxide added for pH adjustment. HYLENEX recombinant has an approximate pH of 7.0 and an osmolality of 280 to 340 mOsm/kg.

Hyaluronidase is an endoglycosidase used to increase the dispersion and absorption of co-administered drugs when administered subcutaneously. It is a glycosylated single-chain protein produced by genetically engineered Chinese Hamster Ovary (CHO) cells containing a DNA plasmid encoding for a soluble fragment of human hyaluronidase (PH20). Hyaluronidase has an approximate molecular weight of 61 kDa. HYLENEX recombinant (hyaluronidase) injection is supplied as a sterile, clear and colorless, nonpreserved, ready-for-use 1 mL solution in a single-dose vial for infiltration use, for interstitial use, for intramuscular use, for intraocular use, for peribulbar use, for retrobulbar use, for soft tissue use, or for subcutaneous use. Each mL contains 150 USP units of hyaluronidase with albumin human (1 mg), dibasic sodium phosphate (1.4 mg), methionine (1.5 mg), polysorbate 80 (0.2 mg), and sodium chloride (8.5 mg). Hydrochloric acid and sodium hydroxide may be added during manufacture to adjust the pH. HYLENEX has an approximate pH of 7.0.
