Experiments on alert rats have shown that, with pre-inhibition of peripheral DOPA-decarboxylase, L-DOPA suppresses behavioral nociceptive reactions without changing hemodynamic ones. Analgetic effect of L-DOPA appears to be related to the stimulation of brain postsynaptic alpha1-adrenoceptors and the drug action on opioidergic systems.
对警觉大鼠的实验表明,在外周多巴脱羧酶预先抑制的情况下,左旋多巴可抑制行为性伤害感受反应,而不改变血液动力学反应。左旋多巴的镇痛作用似乎与脑突触后α1肾上腺素能受体的刺激以及该药物对阿片样物质系统的作用有关。
