Due to unavailability of effective therapeutic agents
and the anticipated time lag between the speed of spread
of the novel corona virus (nCoV) (later re-named as
severe acute respiratory syndrome-coronavirus-2,
SARS-CoV-2) and the discovery of effective vaccines
against corona virus disease-19 (COVID-19), various
available anti-viral, anti-bacterial and anti-malarial drugs
have been re-purposively used by physicians all over
the world, with the hope to cut-down the huge human
death-tolls and sufferings. Available evidences did not
convincingly advocate their clinical use, though some
favorable reports1 exist amid the clinical context of
COVID-19, but few of these evidences are retracted.
