美國食品藥品管理局于2015年10月發(fā)布了“改變劑型和改變給藥途徑藥品非臨床安全性評價指導原則”,包括前言、背景、一般原則、對全身毒性的建議和對給藥途徑的建議5個部分,并且分別描述了15種不同給藥途徑的藥品在改變劑型時應增加的非臨床毒性研究內(nèi)容。我國目前尚無這類指導原則,了解該指導原則對我國完善相應法規(guī)和制定相應的指導原則及其對這類藥物的審評有所啟迪,也對改變劑型類藥物的開發(fā)有所幫助,所以介紹該指導原則的主要內(nèi)容。

FDA issued “Nonclinical Safety Evaluation of Reformulated Drug Products and Products Intended for Administration by an Alternate Route Guidance” in October 2015, including introduction, background, general considerations, systemic toxicity consideration, route of administration considerations, and describing the additional nonclinical toxicity studies for reformulated drug products used in 15 different routes respectively. And there is no such guidance in our country at present. Because understanding the guidance for our country to improve the relevant regulations, to formulate corresponding guidance and to review these drug products are helpful, and for the development of these drug products also is helpful, therefore the main content is introduced.
