[Penetration of the anti-arrhythmia preparation ethmozin through the hemato-encephalic barrier of the guinea pig brain perfused in situ].
In experiment with an artificially perfused guinea-pig brain, labelled ethmosine possessing gamma-activity was used to study the penetration of the drug through the blood-brain barrier. The ethmosine transport constant was found to be in a range of 0.45-0.62 x 10(-3) ml x min-1 x g-1 for various segments of the anterior brain, suggesting that the agent penetrated into the central nervous system very slowly. The slight penetration of ethmosine through the blood-brain barrier may be one of the reasons for this phenothiazine derivative having no marked neurotropic activity.
