Protection against Adriamycin-induced Skin Necrosis in the Rat by Dimethyl Sulfoxide and -Tocopherol¹

Division of Developmental Oncology Research, Mayo Clinic, Rochester, Minnesota 55905

Extravasation of Adriamycin during i.v. infusion can cause serious local complications. We have used a rat skin model to study the protection afforded by dimethyl sulfoxide and -tocopherol (vitamin E) against Adriamycin-induced skin necrosis. Topical daily application of 1 ml dimethyl sulfoxide for 2 days produced a small decrease in ulcer diameter of up to 11% at 2 weeks. Topical daily applications of 1 ml 10% -tocopherol succinate in dimethyl sulfoxide for 2 days produced a marked decrease in ulcer diameter at 2 weeks of up to 68%. Daily topical application of 1 ml 10% -tocopherol succinate in dimethyl sulfoxide for 7 days offered no greater protection than 2-day application. -Tocopherol acetate appeared to have activity slightly less than that of -tocopherol succinate in reducing ulcer size, and both compounds were considerably more active than was -tocopherol alcohol. Administration of -tocopherol succinate or -tocopherol acetate i.p. had no significant effect upon ulcer diameter. Topically applied dimethyl sulfoxide and -tocopherol may provide an effective way of treating accidentally extravasated Adriamycin in cancer patients.
