The role of serotoninergic mechanisms in the effect of psychotomimetic drugs was investigated. Inhibition of the synthesis of serotonin by p-chloro-phenylalanine (p-CPA) markedly reduced behavioural effects of LSD, mescaline and p-bromo-methamphetamine (V-111) in rats and the pyrotogenic effect of LSD and V-111 in rabbits. Blockade of tyrosine hydroxylase activity by α-methyl-p-tyrosine (α-MPT) failed to influence the behavioural effects of the psychotomimetics studied.
