RESUMO
A novel coronavirus, SARS- CoV-2 (2019-nCoV), emerged in December 2019 as an immediate global challenge. Comprehensive efforts at the present time are focused simultaneously on containing the spread of this virus and extenuating the ill effects. There is an immediate need for drugs that can help before a vaccine can be developed. Researchers are endeavoring to find antiviral therapies specific to the virus. As the condition is an emerging, rapidly evolving situation and development of new drugs is a long process, and is unfeasible to face the immediate global challenge. Strategy to reposition the previously used drugs can prove to be effective to combat this difficult to treat pandemic. Several drugs such as Hydroxychloroquine, Umifenovir, Remdesivir, Lopinavir/ Ritonavir, interferon, Darunavir, Favipiravir, Nitazoxanide, etc. are currently undergoing clinical studies to test the safety and efficacy of the drug against this pandemic. The present review gives a snapshot look at the current clinical experience with repurposed antiviral drugs.

Local anaesthetics (LAs) are considered the most effective drugs for prevention and management of pain associated with dental procedures. Lignocaine is the most preferred LA worldwide. Adverse drug reactions reported with lignocaine use are usually mild, however severe complications have been encountered. This article reports a case of lignocaine-induced seizure in a child. We also reviewed similar cases encountered over the last 10 years. The possible explanations could be placement of the needle in a small vein or hypersensitivity to lignocaine. We hereby reinforce the fact that seemingly safe LA's can cause life-threatening complications and rapid identification of clinical symptoms can drastically change the clinical course. Hence it is vital that primary care physicians and other healthcare professionals should to be aware, alert and be able to diagnose and manage these reactions immediately.
