Currently, there are no approved treatments for the fatal infectious coronavirus disease. The process of identifying new applications for approved pharmaceuticals is called drug repurposing. It is a very successful strategy for drug development as it takes less time and cost to uncover a therapeutic agent than the de novo procedure. Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is the seventh coronavirus that has been identified as a causative agent in humans. SARS-CoV-2 has been recorded in 213 countries, with over 31 million confirmed cases and an estimated death rate of 3%. Medication repositioning may indeed be regarded as a unique therapeutic option for COVID-19 in the present situation. There are various drugs and techniques, which are being used to treat the symptoms of COVID-19. These agents are directed against the viral replication cycle, viral entrance, and viral translocation to the nucleus. Additionally, some can boost the innate antiviral immune response. Drug repurposing is a sensible method and could be a vital approach to treating COVID-19. Combining some of the drugs or supplements with an immunomodulatory diet, psychological assistance, and adherence to standards can ultimately act against COVID-19. A better knowledge of the virus itself and its enzymes will enable the development of more precise and efficient direct-acting antivirals. The primary aim of this review is to present the various aspects of this disease, including various strategies against COVID-19.
