[Pharmcokinetics of an echinopsin preparation]

The purpose of the present work is to describe the pharmacokynetic characteristics of the preparation Ehinopsine, which represents N-methyl-gamma-chinoline and is synthetised in NIHFI during 1965. The experiments were carried out on male rats of the strain Wistar with weight of 170 to 190. The authors examine in dynamics plasma and tissues after single intraperitonenal administration of a dose of 30 mg/kg of body weight, plasma after venous administration of 25 mg/kg of body weight and 100 mg/kg of body weight and plasma and tissues-after oral administration of 100 mg/kg of body weight. The excretion of the preparation was examined also in bile, urine and feces after oral administration and there were metabolites in urine. On the basis of the experimental data after oral and venous treatment the respective mathematical models of distribution were determined as well as the basic pharmacokynetic parameters, characterizing the behaviour of Ehinopsine in the organism of rats. The obtained results gave a picture for good resorption of the preparation, quick distribution, weak excretion and wide biotransformation in the organism of the experimental animals.
