HYLENEX RECOMBINANT

HYALURONIDASE RECOMBINANT HUMAN
Approved 2005-12-02

Hylenex Recombinant is an endoglycosidase used as an adjuvant to improve the delivery and absorption of other substances. It is indicated for subcutaneous fluid administration to achieve hydration and to increase the dispersion of other injected medications. Additionally, the drug is used in subcutaneous urography to improve the resorption of radiopaque agents. It functions as a facilitating agent rather than a primary treatment for a specific disease.

How HYLENEX RECOMBINANT Works

This drug works as a dispersion agent by modifying the permeability of connective tissue through the hydrolysis of hyaluronic acid. Hyaluronic acid is a major component of the intercellular ground substance that holds cells together. By splitting the bonds within this acid, the enzyme temporarily decreases the viscosity of the cellular cement. This process facilitates the spread and absorption of injected fluids or localized exudates throughout the tissue.
