Have you heard of clinical trials? Do you know how the drugs we usually use, especially new drugs, are obtained? If you haven't heard of it before but are particularly interested, then we can talk about clinical trials of new drugs together.


Everyone knows that drugs can prevent and treat diseases. The development of medicine is closely related to the health level of the people, and the research and development of new drugs is even more important.


Since the 1950s, Drug development has made remarkable progress. Previously incurable diseases have corresponding therapeutic drugs, and until now, we have been continuously developing various drugs that are more effective in treating diseases. Many years ago, it was believed that incurable diseases can also be controlled and even cured, greatly improving the quality of life and subjective feelings of patients.


So how are new drugs applied to the general public?


After scientists find compounds that are effective for diseases, they need to conduct laboratory research, Animal testing, and then conduct human clinical trials on the basis of ensuring human safety. Some clinical trials of new drugs involve testing new drugs, while others are old drugs that have been on the market for many years but have new uses. The purpose of these trials is to confirm whether new drugs are safe and effective. There are many types of clinical trials for new drugs. According to the purpose of the trial, the trial can observe how the drug works in the human body, where does the drug go to the human body after ingestion or injection, and how does it get out? When did you go out? How do these drugs work? Besides good therapeutic effects, is it safe? Are there any adverse reactions we don't want? Understanding these things requires detailed clinical trials.


When a drug is made, why can't it be sold on the market directly, but rather do a very complicated Human subject research first?
Everyone knows that there is a story of Shennong tasting a hundred herbs in ancient times, because all drugs may have adverse reactions. If drugs are not safe, they not only cannot treat people's illnesses, but may also bring great trouble! In order to gain a clear understanding of drugs, complex clinical trials of new drugs are now required before they are launched. New drugs have accumulated a lot of data in clinical trials, so that before doctors prescribe drugs to patients, they can know the treatment effect of a new drug, the population using the treatment, and potential adverse reactions. This way, patients will be safer when using it.


Some people may say, "Isn't this just a little white mouse?" First of all, I want to tell you that this is definitely impossible. All new drugs have already undergone animal experiments before entering clinical trials. Any researcher conducting a certain experiment must ensure that it does not harm the interests of patients, otherwise the experiment cannot be approved by the ethics committee. And all drug clinical trials must follow the following three basic principles: ethical, scientific, and regulatory principles. Protecting the rights and interests of the subjects is always throughout the entire experiment, and you have the right to withdraw early at any time.
