The emergence of the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), responsible for causing coronavirus disease 2019 (COVID-19), marked the third time in the twenty-first century when a new, highly pathogenic human coronavirus outbreak has led to an epidemic. The COVID-19 epidemic has emerged in late December 2019 in Wuhan city of China and spread rapidly to other parts of the world. This quick spread of SARS-CoV-2 infection to many states across the globe affecting many people has led WHO to declare it a pandemic on March 12, 2020. As of July 4, 2020, more than 523,011 people lost their lives worldwide because of this deadly SARS-CoV-2. The current situation becomes more frightening as no FDA-approved drugs or vaccines are available to treat or prevent SARS-CoV-2 infection. The current therapeutic options for COVID-19 are limited only to supportive measures and non-specific interventions. So, the need of the hour is to search for SARS-CoV-2-specific antiviral treatments and to develop vaccines for SARS-CoV-2. Also, it is equally important to maintain our immunity, and natural products and Ayurvedic medicines are indispensable in this regard. In this review, we discuss recent updates regarding various therapeutic approaches to combat COVID-19 pandemic and enlist the major pipeline drugs and traditional medicines that are under trial for COVID-19. Also, possible mechanisms involved in viral pathogenesis are discussed, which further allow us to understand various drug targets and helps in discovering novel therapeutic approaches for COVID-19. Altogether, the information provided in this review will work as an intellectual groundwork and provides an insight into the ongoing development of various therapeutic agents.
