[Effect of several neuroleptic, adreno-, sympatho- and cholinolytic substances on the development of experimental cerebral edema induced by nicotine].

The influence of some neuroleptic, adreno, sympatho- and cholinolytic substances on the development of experimental brain edema induced with nicotine was studied in tests conducted on rats. It was ascertained that marked antiedemic properties display drugs blocking the alpha-adrenoreceptors (phentolamine, dopegit), the neuroleptic chlorpromazine and central M-cholinolytics (benactizine). Weak action exert central H-cholinolytics (difacil trasentin) and the neuroleptic galoperidol. Sympatho- and beta-adrenolytics (guanethidine, alpha-methyltyrosine, obsidan), and also the neuroleptic triphthazine fail to prevent the development of an experimental brain edema. It is presumed that a brain edema induced with nicotine comes as a result of the catecholamines liberation and is also due to stimulation of alpha-adrenoreactive systems.
