Priority Review
AMPHADASE (hyaluronidase) by R-Pharm US is agent, which modifies the permeability of connective tissue through the hydrolysis of hyaluronic acid, a polysaccharide found in the intercellular ground substance of connective tissue, and of certain specialized tissues, such as the umbilical cord and vitreous humor. First approved in 2004.

AI summarySynthesized from FDA + DailyMed + ClinicalTrials.gov data
AMPHADASE (hyaluronidase) is an endoglycosidase enzyme that hydrolyzes hyaluronic acid in connective tissue, temporarily decreasing viscosity and promoting dispersion of injected fluids or localized fluid collections. It is administered via injection to facilitate absorption of exudates, transudates, and co-administered medications through enhanced tissue permeability. The mechanism involves cleaving glycosidic bonds in hyaluronic acid and related acid mucopolysaccharides of connective tissue.
