摘要: PHENOTHIAZINES and related neuroleptic drugs, such as thioxanthenes, markedly increase the content of homovanillic acid (3-methoxy-4-hydroxyphenylacetic acid) in brain, especially extrapyramidal centres various animal species. This has raised question whether drugs accelerate synthesis catecholamines through a feed-back mechanism either result blockade dopaminergic noradrenergic receptors or alteration amine storage1–6,16. The present communication shows that vivo chlorpromazine neuroleptics enhance hydroxylation tyrosine which seems to be rate-limiting step formation catecholamines7.
