The development of new drugs is a complex and lengthy process. It starts with an idea and requires a wide range of skills to bring that idea to fruition: synthesis or extraction of more or less complicated molecules, proof of their therapeutic effect in cell cultures and animals, testing for toxicity, and clinical studies.
新药的研制是一个复杂而漫长的过程。它发端于一个理念，并需要广泛的技能才得以实现：更为复杂或更加简单的分子的合成或提取，它们在细胞组织和动物身上的治疗作用验证，毒性试验和临床研究。
