Drug repositioning is a drug discovery strategy that utilizes existing drugs as treatment for other diseases. As information regarding the safety, pharmacokinetics, and formulation of existing drugs is already available, the cost and time required for drug development is reduced. Drug repositioning has been dominated by a method involving the search for candidate drugs that act on the target molecules of an organism in a diseased state. 

 Due to the development of artificial intelligence and other innovative technologies, advances in drug repositioning are expected.
