title: [Correlations between the pharmacological effects of menilon and its concentrations in the plasma and brain of experimental animals].
abstract: The authors carried out studies on the preparation menilon in order to establish eventual correlations between some pharmacological and pharmakokinetic indices. For this purpose they examined the activity of menilon in rats and mice during electric shock and hypothermia and determined the concentrations of the preparation in plasma and brain in rats. The obtained results from the pharmacological investigation revealed manifested action against the seizures after electric shock in both groups of animals. It was established as early as 30 minutes after oral administration of the preparation reached maximal activity after 1-2 hours and disappeared after 6 hours. The authors found strong and continuous hypothermic activity. The hypothermic effect of the doses used was preserved up to the end the 24 th hour. The lowering of temperature in rats was comparatively weaker and shorter. The pharmacokinetic studies showed quick oral resportion of menilon. It was found in plasma and brain of the experimental animals on the 30 th minite after its administration, reached maximal concentration between the first and second hour and still was established on the 24 th hour after administration. The maximal level of the preparation in plasma and brain after oral administration correlated well with the time of maximal activity of its antiseizure and hypothermic effects. The preparation menilon was comparatively slightly toxic.
