Keywords:美国加州论文代写 药物开发阶段

一种药物的开发有5个阶段，直到病人可以使用它。第一个阶段是发现和发展，在这个过程的第一部分，许多物质都有很大的潜力成为一种药物，然而，经过一些测试后，只有少数物质被批准进入第二阶段。在第二阶段也称为临床前研究人员需要找出如果物质有一个潜在的损坏原因,测试也称为毒性和可以执行在体外或体内,通常并不长久的临床前研究,但是这些研究应该显示信息水平的毒性,然后物质是否可以在人类身上进行测试。药物发展的第三阶段,临床研究,指的是对人类的研究和试验,此时在开发人员组织一个研究计划协议和精心设计的问题和目标,他们打算回应举个例子,有多少人被研究的一部分或如何传递给病人和药物剂量。完整的过程需要大约十年,因此第四阶段审查后的药物进行的所有步骤,完成在第五阶段,这是药物的上市后药物安全监测已经访问了消费者,但监控未完待续。

The development of a drug has 5 stages until it becomes accessible to the patients. The first stage is the discovery and development, in this first part of the process many substances possess a great poise to become a medical treatment, and however, after some test only a few are approved for phase two. In the second stage also called preclinical researchers need to find out if substances have a potential cause of damage, the test is also called toxicity and can be performed in vitro or in vivo, normally preclinical studies are not long lasting, but the studies should show information on levels of toxicity and then whether the substance can be tested in humans. The third phase of drug development, Clinical Research, refers to the study and trials that are done on humans, at this point in the development the researchers organize a study plan called protocols and elaborate questions and objectives that they intend to respond for example, how many people have been part of the study or how the drug will be passed on to patients and in which dosage. The complete process can take about ten years, thus following the fourth phase where a review of all the steps of the drug is carried out, finishing in the fifth phase, which is the Post-Market Drug Safety Monitoring where the drug is already accessible to the consumer, but monitoring to be continued.
