Repurposing drugs is a strategy that allows for the discovery of new uses for approved or experimental medicines. It has the potential to improve the efficacy and reduce side effects of the original product. The benefits of repurposing a drug are numerous. Here are a few:
Drug repurposing is an approach to finding new uses of approved or investigational drugs.
A novel strategy for progressing research and development is to develop a new drug use. The most rewarding objective of drug research is to develop novel therapies. This process is much more achievable than the time-consuming and costly process of de novo drug discovery. The medicines have already been approved so repurposing is much more likely. Despite the fact that there may be fewer clinical studies needed, the petitioner still must conduct a clinical trial in order to establish safety and efficacy at higher doses than the approved dosage.
Repurposing can be described as repositioning or re-profiling and the rescue of drugs. This approach is characterized by the convergence of several disciplines - basic sciences, clinical research, and medicine. For instance, academic units that are not backed by large foundations should consider creating an Experimental Drug Network, which would provide non-competitive advice to pharmaceutical companies. This network could be built around CTSA. This would enable these academic units access to the highly skilled work-force in the pharmaceutical industry.
It decreases mortality and morbidity
Repurposing, in the treatment of cancer, is used to treat patients who do not respond to standard treatments. Using an off-patent medicine to treat cancer can reduce costs while providing a better treatment option. This is particularly true for rare and advanced cancers. They account for 20% to 20% of all new European cancer cases. Repurposing used to be based on an ad hoc discovery process, but nowadays, systematic data-driven approaches are used to discover new medicines and compounds. The use of computational assistance in repurposing is increasing, which includes Big Data and artificial intelligent.
It is an efficient way to quickly provide new treatments by repurposing old drugs that have been used to treat cancer. It also identifies new uses for drugs that already have a high profile. Multiple drugs have been successfully reused for different diseases. You can repurpose drugs for different diseases at any stage of drug discovery, but it's most effective when the drug has been approved for another indication.
It increases efficiency
Repurposing drugs means repurposing an older or less successful drug for a new purpose. Drugs can now be identified as having a gene transcription signature, which provides insight into how molecules function in the body. This information forms the basis of the new indications that repurposed drugs can be used. This method may prove to be more efficient and produce evidence quicker. The preclinical stage, animal models, as well as safety testing are the first steps. Next, a clinical program will be conducted and then approval.
Repurposing drugs offers many benefits. It is possible to accelerate traditional drug discovery, find new clinical uses for an already existing drug, and lower the cost of drug development. It works by using the same molecular pathways as in various diseases. This means that a drug's efficacy in one setting may be improved by repurposing it to a different application. However, this also increases the computational complexity. It requires more computational power and time.
It lowers side effects
Repurposing existing drugs has numerous benefits, including cost-effectiveness and time savings. Although clinical and preclinical research are not always reliable due to the fact that they may have focused on different aspects, these studies can still be useful in determining the drug's mechanism. Furthermore, the process of developing a new drug can involve repeated steps, resulting in new-product approval with all of the associated costs and risks. This article explores the logic behind drug repurposing and discusses some approaches to repurposing.
Repurposing falls into several categories, including "off-label" use, "on-label" use, and repositioning for clinical trial. Physicians have the right not to be listed as an indication for a drug. But, scientific societies and regulatory agencies often disapprove of this "off-label” use. Moreover, the effectiveness and safety of a drug for an off-label indication may not be well-established. It is necessary to invest significant money to get approval for a novel indication. To guarantee a return on your investment, you will need a patent.
