Drug Repurposing: A Leading Strategy for New Threats and Targets

Ashish Sriram Mishra et al. ACS Pharmacol Transl Sci. .

Abstract

Less than 6% of rare illnesses have an appropriate treatment option. Repurposed medications for new indications are a cost-effective and time-saving strategy that results in excellent success rates, which may significantly lower the risk associated with therapeutic development for rare illnesses. It is becoming a realistic alternative to repurposing "conventional" medications to treat joint and rare diseases considering the significant failure rates, high expenses, and sluggish stride of innovative medication advancement. This is due to delisted compounds, cheaper research fees, and faster development time frames. Repurposed drug competitors have been developed using strategic decisions based on data analysis, interpretation, and investigational approaches, but technical and regulatory restrictions must also be considered. Combining experimental and computational methodologies generates innovative new medicinal applications. It is a one-of-a-kind strategy for repurposing human-safe pharmaceuticals to treat uncommon and difficult-to-treat ailments. It is a very effective method for discovering and creating novel medications. Several pharmaceutical firms have developed novel therapies by repositioning old medications. Repurposing drugs is practical, cost-effective, and speedy and generally involves lower risks when compared to developing a new drug from the beginning.

Illustration of the advantages of drug repurposing. Drug repurposing is a prominent approach used in the field of pharmaceutical research, whereby novel therapeutic applications for pre-existing medications are identified. The use of this approach has many notable benefits, including accelerated development processes, reduced risk factors, enhanced treatment possibilities, improved patient outcomes, sustainable practices, versatile applications, cost-effectiveness, and identification of synergistic combinations of pharmaceutical agents. Nevertheless, the industry has obstacles, such as the task of discerning appropriate people and maneuvering through regulatory processes for novel applications. Thorough assessment and scholarly investigation are required in order to effectively harness the potential advantages of pharmaceutical repurposing.

Drug repurposing and conventional drugs: a comparative analysis. The comparative study conducted between medication repurposing and traditional drug development elucidates significant disparities in the methodologies used in pharmaceutical research. The concept of drug repurposing, as examined within this framework, entails the identification of novel applications for pre-existing medications, in contrast to traditional drug discovery which primarily centers on the development of totally new chemical compounds for therapeutic purposes. The purpose of this comparative study is to highlight the benefits, drawbacks, and changing frameworks in the domain of pharmaceutical research and development. Ultimately, this analysis helps in making better-informed decisions and allocating resources more effectively in the quest for innovative therapeutic interventions.
