The influence of haloperidol and propranolol on aggressiveness, motility exploration and general behavior, and the activity or level of adenylate cyclase, cyclic AMP, and protein kinase in the brain of mice treated with LSD was tested. Haloperidol evidently, and propranolol slightly less, inhibited the behavioral and biochemical changes induced by LSD. It is suggested that psychotomimetic effects of LSD depend on complex action of this compound on aminergic receptors in the central nervous system, and the antipsychotic effectiveness of haloperidol and propranolol is related to interaction of these drugs and LSD with the receptors for monoamines participating in the central neuromediation.
