药物相互作用是极其复杂的,它涉及到药物的理化性质、作用机理、体内过程、受体或作用部位效应;食物或环境污染物质对药物的影响;遗传基因以及药物对临床检查值的干扰等许多方面因素,概括起来,可分为以下几类: 一、药物之间的相互作用1.物理、化学的相互作用:物理化学的配伍禁忌。根据作用形式又可分为: (1) 形成非吸收性螯合物:四环素族抗生素与Ca~(++)、Mg~(++)、Bi~(++)、Al~(++)等盐类制酸剂或铁剂形成非吸收性螯合物,从而使抗生素吸收降低,影响各自
Drug interactions are extremely complex and involve the physicochemical properties of the drug, its mechanism of action, the in vivo processes, the site effect of the receptor or site of action, the effect of food or environmental contaminants on the drug, the interference of genes and drugs in clinical tests, etc. Many aspects, in a nutshell, can be divided into the following categories: First, the interaction between drugs 1. Physical and chemical interactions: Physical and chemical compatibility taboo. According to the role of form can be divided into: (1) the formation of non-absorbing chelate: tetracycline antibiotics and Ca ~ (++), Mg ~ (++), Bi ~ (++), Al ~ Salt-based antacids or irons form non-absorbing chelates, reducing the absorption of antibiotics, affecting each
