The newly emerged coronavirus SARS-CoV-2, first reported in December 2019, has infected about five and a half million people globally and resulted in nearly 9063264 deaths until the 24th of June 2020. Nevertheless, the highly contagious virus has instigated an unimaginably rapid response from scientific and medical communities. ⋯ An innovative analysis is evaluating the nature of the COVID-19 pandemic. The aim is to increase knowledge of possible viral detection methods, which highlights several new technology limitations and advantages. We have assessed some drugs currently for patients (Lopinavir, Ritonavir, Anakinra and Interferon beta 1a), as the feasibility of COVID-19 specific antivirals is not presently known. The study explores the race toward vaccine development and highlights some significant trials and candidates in various clinical phases. This research addresses critical knowledge gaps by identifying repurposed drugs currently under clinical trials. Findings will be fed back rapidly to the researchers interested in COVID 19 and support the evidence and potential of possible therapeutics and small molecules with their mode of action.

Intranasal Drug Delivery: A Non-Invasive Approach for the Better Delivery of Neurotherapeutics.
The convoluted pathophysiology of brain disorders along with penetration issue of drugs to brain represents major hurdle that requires some novel therapies. The blood-brain barrier (BBB) denotes a rigid barrier for delivery of therapeutics in vivo; to overcome this barrier, intranasal delivery is an excellent strategy to deliver the drug directly to brain via olfactory and trigeminal nerve pathways that originate as olfactory neuro-epithelium in the nasal cavity and terminate in brain. ⋯ Recently few reports have proven that nasal to brain drug delivery system bypasses the BBB. This novel route is associated with targeting efficiency and less exposure of therapeutic substances to non-target site. Nevertheless, this route desires much more research into the safe transferring of therapeutics to the brain. Role of muco-adhesive polymer and surface modification with specific ligands are area of interest of researcher to explore more about this.
