Pharmacokinetics of copolymers of n-vinylpyrrolidone with acrylic acid. Article 1

The authors studied the pharmacokinetics of the copolymers of n-vinyl-pyrrolidone (I) with acrylic acid (II) (copolymer III) using the radioactive isotope /sup 125/I. In experiments on mice, they studied the distribution of a copolymer of I with II (/sup 125/I-III) in the organism of the animals. The content of /sup 125/I-III and its possible radioactive metabolites in the blood and organs of mice after a single intravenous administration of the given preparation is shown. The radioactivity of organs after butanol extraction is presented.
