In today's world where current medical treatments have reached their peak, many highly effective drugs have been developed with various technologies and unfortunately, despite the development of sophisticated drugs, there are still incurable diseases in the world. However, due to the lack of sufficient funds on a global scale and the inability to access treatments due to the inadequacy of various health policies, many patients cannot be provided with the magnificent fountain of life called "treatment". To some extent, even the limited focus area on developing new scientific perspectives can be compatible with this sad result. The development of biotechnological drugs and their prominent applications in current treatments are increasingly receiving investment and are considered worthy of attention. In addition to the traditional production of many drugs used in treatment, technological developments inevitably change the fate of drug development. In this section, by giving a little favor, examples were presented where biotechnological drugs seem to have won the war against conventional drugs.
