Influence of insulin on pharmacokinetics of mannosulfan in rats.

Abstract

The purpose of the present study was to investigate the possibilities of potentiation of the antitumor action of mannosulfan after its administration together with insulin. The pharmacokinetics of mannnosulfan were investigated after its administration separately and together with insulin. Concentrations of mannosulfan in the plasma were determined by gas chromatography. Insulin enhanced the rate of absorption of mannosulfan from the peritoneal cavity and prolonged its elimination from the body. It may be assumed that insulin enhances not only passage of mannosulfan from the peritoneal cavity to blood, but also from blood to tissues. Since increased antitumor effectiveness of mannosulfan was accompanied by its decreased toxicity, it may be concluded that insulin causes selective cummulation of the cytostatic only in some tissues, among others, in the tumor.
