There is indeed a large gap between the quality of generic drugs in my country and the original research drugs. At present, most of the domestic production of generic drugs refers to incomplete and irregular standards, and some are produced in accordance with the standards of other generic drugs, which are different from the original drugs in terms of safety and effectiveness. Big gap. The pharmaceutical industry estimates that more than 70% of domestic generic drugs have a gap between the efficacy of the original drugs. In terms of treatment, the risk of side effects of generic drugs is far greater than that of original drugs. For example, the generic drug ampicillin, even if the penicillin skin test is negative, you must be highly alert to the possibility of drug eruption; there are also some generic antifungal drugs, which have more toxic side effects such as skin rash and damage to the kidney and liver than the original drug. high.

Bi Jingquan: "The consistency evaluation of the quality and efficacy of the generic drugs that have been approved for marketing is a lesson in history. Because the drugs we approved for marketing in the past did not have mandatory requirements for the evaluation of the quality and efficacy of the original drugs, so some There is some gap between the efficacy of drugs and the original research drugs. The gap between the drugs approved for marketing before 2007 is even greater. You all know the stories that happened in that era. In history, the United States, Japan and other countries have also experienced the same process. Japan uses It took more than ten years to advance this work. The consistency evaluation of quality and efficacy requires that the quality and efficacy of the generic drugs that have been approved for marketing should be consistent with the original drug in terms of quality and efficacy, and they can be replaced by the original drug in clinical practice. This is conducive to saving social medical expenses.

1. The main body of the consistency evaluation is the enterprise, and the enterprise should actively look for product reference preparations, research and conduct clinical trials according to the prescribed methods.

This is also a huge challenge for enterprises, but this work will improve the quality of the development of the pharmaceutical industry, and truly transform our country’s pharmaceutical industry from a major pharmaceutical country to a powerful pharmaceutical country, and truly enable the preparations and drugs we produce to enter the international market. , Are all crucial. "
