With this technique, the identification of stages can be done even on the next day. Hormonal variation in blood and histomorphological changes in ovaries at different stages of the estrous cycle were studied in female Wistar rats, which can be used to determine the hormone levels in works related to hormonal drugs, further ovarian morphology can be used to study changes in ovaries during the estrous cycle. This study aims to report a rapid and simple method for vaginal cytology using crystal violet and to report normal hormonal levels and histomorphology of ovaries in various phases of the estrous cycle.

Target identification, target validation; lead identification; and lead optimization are a lengthy and unreliable process that further complicates the discovery of new drugs. A study of more than 15 years reports that the success rate in the discovery of new drugs in the fields of ophthalmology, cardiovascular, infectious disease, and oncology to be 32.6%, 25.5%, 25.2% and 3.4%, respectively. A tedious and costly process coupled with a very low success rate makes the traditional drug discovery a less attractive option. Therefore, an alternative to traditional drug discovery is drug repurposing, a process in which already existing drugs are repurposed for conditions other than which were originally intended. Typical examples of repurposed drugs are thalidomide, sildenafil, memantine, mirtazapine, mifepristone, etc. In recent times, several databases have been developed to hasten drug repurposing based on the side effect profile, the similarity of chemical structure, and target site. This work reviews the pivotal role of drug repurposing in drug discovery and the databases currently available for drug repurposing.
