用实验动物进行新药安全性研究是为药物用于人体时提供某些预期可能产生的作用。在安全评价的开始阶段在人和实验动物中进行交叉研究,随着临床研究的进展就需要另外进一步的动物资料去支持临床扩大试验和支持作为药物医疗推广的适用性。关于人的临床研究的开始或继续,应当由药理学家, New drug safety studies with laboratory animals provide some of the anticipated potential benefits of drugs when used in the human body. Cross-sectional studies in humans and laboratory animals at the beginning of the safety assessment require further additional animal data to support clinical expansion of the trial and support for its applicability as a medical medical extension as clinical research progresses. With regard to the beginning or continuation of human clinical studies, pharmacologists,
