ABSTRACT
The neurotropic activity, toxicity and pharmacokinetics of triftazine in the form of syrup and powder were subjected to a comparative study on albino mice, rats and dogs. Investigations demonstrated that as follows from the tests under study these drugs display an egual depressing activity. Triftazine from the syrup was found to quicker enter the blood and was detected later in it (after 24 hours). The toxicity of peroral triftazine administered to mice and rats is the same for both dosage forms, it being somewhat higher for intraperitoneal triftazine syrup.

It is shown that the replacement of the ethyl or methyl radical in the molecules of aethaperazine or metherazine with the adamantyl one results in the appearance of a singular immunotropic activity. Such a drug (adapiprazine) exerts an immunodepressive action both on the primary and secondary response of the mice immunized with sheep erythrocytes. The immunodepressive action of adapiprazine is manifest with a low-dosage optimum introduced before immunization. In analogous conditions aethaperazine and metherazine fail to display any immunodepressive action. Adapiprazine arrests the rejection of a skin allotrasplant in mice differing from the donors in the presence of a strong histocompatibility locus. In in vitro tests adapiprazine in a concentration of 10(-5) mol and less has no effect on the spontaneous migration of leucocytes in the capillary, nor upon the process of immune roset-formation.
