Abstract
The influence of the route of administration (i.v., i.p. and s.c.) on pharmacokinetics and tissue distribution of bovine testicular hyaluronidase and vinblastine was studied in mice (plasma, skeletal muscle, liver, kidney and human melanoma). After i.v. injection, hyaluronidase was accumulated in liver and kidney, whereas i.p. and s.c. administration led to almost equal distribution in plasma, ...
Abstract
The influence of the route of administration (i.v., i.p. and s.c.) on pharmacokinetics and tissue distribution of bovine testicular hyaluronidase and vinblastine was studied in mice (plasma, skeletal muscle, liver, kidney and human melanoma). After i.v. injection, hyaluronidase was accumulated in liver and kidney, whereas i.p. and s.c. administration led to almost equal distribution in plasma, muscle, liver and kidney. In melanoma, the highest levels of hyaluronidase were found after s.c. injection of the enzyme close to the tumor. Hyaluronidase s.c. increased the intratumoral concentration of s.c. co-administered vinblastine most efficiently, making local simultaneous application as in interstitial chemotherapy most promising.
