Pharmacokinetics of 14C-N-N'-dicyclopropyl-methyl-piperazine-dichlorhydrate. 2nd communication: tissue distribution in rats.

The distribution of radioactivity in rats after intravenous or oral administration of 14C-labelled N-N'-dicyclopropyl-methyl-piperazine-dichlorhydrate (14C-Ino 2628-CZ) demonstrated that the labelled compound was widely distributed in the body. An important diffusion of the isotope was found in the central nervous system, the gastric mucosa and several glands. Only small amounts of radioactivity were found in these organs 24 h after dosage.

Pharmacokinetics of 14C-N-N'-dicyclopropyl-methyl-piperazine-dichlorhydrate. 1st Communication: balance of elimination, plasma and blood kinetics, metabolism in rats.

N-N'-Dicyclopropyl-methyl-piperazine-dichlorhydrate (Ino 2628-CZ) is a novel inotropic compound. The absorption, distribution, excretion and metabolism of radiochemically labelled 14C-Ino 2628-CZ has been studied in male and female rats after intravenous and oral administration. The compound was mainly excreted during the first 24 h after both administrations, although traces of radioactivity were still measured at 7 days post-dose.
