Drug Repurposing: A Quick and Easy Way of Finding New Medicines

Abstract

Every year, we face infectious outbreaks produced by harmful microorganisms commonly called superbugs. Often, there is not enough time to find new treatments to cure infected patients. On average, it takes a decade to develop a promising new drug to the point where it can be used on patients! Also, many of the compounds that we identify in the laboratory as promising anti-infectives are not useful for treating patients, mainly because they have unexpected, unsafe side effects. However, researchers have already found thousands of drugs that can safely be used to treat specific diseases. These compounds are approved to be used on patients for particular illnesses, but many of them have not been tested to treat any other diseases. Some of these drugs could be repurposed to treat infections caused by new superbugs. In this article, we summarize some exciting strategies used to find new anti-infectives by drug repurposing.
