The distinction between pharmaceutical equivalent and pharmaceutical alternative drug products can lead to considerable confusion, especially with the proliferation of various branded, alternative, and generic medications that contain the same active ingredient. To illustrate this problem, four examples of medication products containing the active ingredients paroxetine, venlafaxine, bupropion, and valproate will be described. Understanding these differences is important for nurses providing patient care. Only generic drugs can be freely substituted for a brand-name product. Switching to a pharmaceutical alternative requires a change in prescription. Finally, the use, labeling, and cost of branded, alternative, and generic medications may be different.
药学等效药品和药学替代药品之间的区别可能会导致相当大的混淆，尤其是随着含有相同活性成分的各种品牌药、替代药和仿制药的激增。为说明这个问题，将描述四种含有帕罗西汀、文拉法辛、安非他酮和丙戊酸盐活性成分的药品实例。理解这些差异对于提供患者护理的护士来说很重要。只有仿制药可以自由替代品牌药产品。改用药学替代药需要更改处方。最后，品牌药、替代药和仿制药的使用、标签和成本可能会有所不同。
