Used to increase the absorption and dispersion of injected drugs by breaking down hyaluronic acid in connective tissues. Commonly applied in subcutaneous fluid administration, enhancing local anesthetics, and improving the spread of contrast agents in diagnostic procedures. Also utilized in ophthalmic surgery to facilitate tissue permeability and in cancer therapy to improve drug penetration into tumors. Its enzymatic action helps reduce viscosity, allowing better diffusion of fluids in tissues.
