一、序言 肾上腺能受体激动剂,亦称为拟交感神经药物。这类药物的作用与交感神经兴奋的效果一致。肾上腺能受体激动剂指的是直接与受体作用,并引起相应效应的药物。机体的很多重要功能,是通过肾上腺素和去甲肾上腺素完成的,前者是激素,后者是神经传导递质,均归属于肾上腺能受体激动剂。交感神经兴奋引起生理和生化反应的结果,使机体在短时内,动员了大量可利用的能量,以应付紧急情况,所以肾上腺素和去甲肾上腺素在保护自体和适应环境过程中,起着关键作用。组织中的肾上腺能受体分为两大类,即肾上腺能α受体和β受体,这些受体又进而分为不同的亚型受体,即α_1和α_2及β_1
First, the preamble Adrenergic receptor agonists, also known as sympathomimetic drugs. The role of these drugs and sympathetic nerve stimulation effect. Adrenergic receptor agonists refer to drugs that act directly on the receptor and cause a corresponding effect. Many important functions of the body through the epinephrine and norepinephrine to complete the former is a hormone, the latter is a neurotransmitter neurotransmitter, are attributed to adrenergic receptor agonists. Sympathetic nerve excitation caused by physiological and biochemical reactions, the body in a short time, mobilized a large amount of available energy to deal with emergencies, so adrenaline and norepinephrine in the protection of self and adapt to the environment, play Key role. Adrenergic receptors in the tissue are divided into two broad categories, ie, adrenergic alpha receptors and beta receptors, which in turn are subdivided into different subtype receptors, namely alpha 1 and alpha 2 and beta 1
