[Pharmacokinetics of the antitumor drug oxoplatinum labeled with 191Pt].

Abstract

A pharmacokinetic study of the antitumor drug oxoplatinum labeled with 191Pt when administered to control mice and mice with B-16 melanoma have shown that distribution of the drug in organs and tissues in both groups of animals is nonuniform. The drug is more tropic to the kidneys, liver, spleen, adrenals, thymus, skin and tumor. Correlation was established between the values of the coefficient ratios of differential accumulation (CDA) of the organ/blood in the final and initial periods of observation and the period of the drug half-life in the organs. The higher the CDA of the organ/blood the longer the period of the drug half-life. The excretion of the drug from the blood and most other organs is described by a bioexponential curve.
