Application of artificial intelligence in drug repositioning

The use of artificial intelligence technologies in biology, pharmacy, and medicine has brought about a dramatic change in these industries. Drug repositioning is a method of drug development in the process of applying existing therapeutic agents to new diseases. This paper first outlines the use of artificial intelligence technology in the field of drug repositioning, then reviews a variety of application methods of artificial intelligence in the realm of drug repositioning, and finally summarizes the advantages and disadvantages of these methods, and proposes the difficulties faced by artificial intelligence in drug repositioning in the future and the corresponding suggestions to achieve the goal of helping researchers to develop more effective methods of drug repositioning.
