耐受性 是机体对药物反应性降低的一种状态,按其性质有先天性和后天获得性之分。前者的耐药性可长期保留;后者往往是连续多次用药后发生的,增加剂量后可能达到原有的效应,停止用药后,其耐受性可以逐渐消失,机体恢复到原有的对药物反应水平。 耐药性 又称抗药性,一般是指病原体的药物反应性降低的一种状态。这是由于长期应用抗菌药,病原体通过产生使药物失活的酶、改变原有代谢过程,而产生的一种使药物效果降低的反应,因而使用的剂量要不 Tolerance is a condition in which the body responds to medication and is congenital and acquired by its nature. The former drug resistance can be long-term retention; the latter is often occurred after repeated doses, the dose may be achieved after the original effect, stop medication, its tolerance can gradually disappear, the body back to the original Drug response level. Drug resistance, also known as drug resistance, generally refers to a state of reduced pathogen drug response. This is due to the long-term use of antibacterial drugs, pathogens through the production of the enzyme inactivation of drugs to change the original metabolic process, resulting in a drug to reduce the effect of the reaction, so the dose or not
