Excretion and distribution studies in rats with two forms of 14carbon-labelled polyvinylpyrrolidone with a relatively low mean molecular weight after intravenous administration.

Excretion and autoradiographic distribution studies were performed in rats with two 14C-labelled polyvinylpyrrolidone preparations, both of relatively low mean molecular weight but different in molecular weight distribution. At different time intervals after i.v.

A combined study on the distribution of oxytetracycline and polyvinylpyrrolidone in rats.

With the purpose of studying the influence of polyvinylpyrrolidone (PVP) on the disposition of oxytetracycline (OTC), OTC was administered i.v. to male rats in two formulations, one of which contained 14C-labelled PVP.
