随着医学科学的发展和临床实践需要,常将数种注射剂混合使用,不但可减少多次注射的痛苦,而且从医疗需要角度上来考虑,各种药品都有一定特性和局限性,因此配伍用药很有必要。但每种药品的理化性质不同,配伍后可引起药理上的拮抗作用或协同作用,物理和化学上的配伍变化;如变色、混浊或沉淀等可以从外观上观察得到,有些变化则观察不到,但由于产生了变化,改变了原来的性质,使用时忽视这些问题,不作深入调查研究,除可降低疗效或产生副作用外,甚至可引起致命的危险。今从某公社医院寄来两张处方为例,以供用
With the development of medical science and the need of clinical practice, several injections are often used in combination, which not only reduces the pain of multiple injections, but also considers from the point of view of medical needs, various drugs have certain characteristics and limitations, so the compatibility of drugs necessary. However, the physical and chemical properties of each drug are different. After compatibility, it can cause pharmacological antagonism or synergistic effects, physical and chemical compatibility changes, such as discoloration, turbidity, or precipitation can be observed from the appearance, and some changes can not be observed. However, due to changes, changes in the original nature, use of these issues are ignored, do not conduct in-depth investigation and study, in addition to lower efficacy or side effects, and even can cause fatal dangers. Here are two prescriptions sent from a commune hospital for example.
