AMPHADASE (hyaluronidase)

Other Approved 2004-10-26

Amphadase is an endoglycosidase enzyme used as an adjuvant to facilitate the administration and absorption of fluids and medications. It is indicated for use in subcutaneous fluid administration for hydration and to increase the dispersion of other injected drugs. Additionally, the agent is utilized in subcutaneous urography to improve the resorption of radiopaque agents.

How AMPHADASE Works

Hyaluronidase functions as a dispersion agent by hydrolyzing hyaluronic acid, a polysaccharide found in the intercellular ground substance of connective tissue. By splitting specific glucosaminidic bonds, the enzyme temporarily decreases the viscosity of the cellular cement and increases tissue permeability. This process promotes the dispersion of injected fluids or localized transudates, thereby facilitating their absorption into the body.
