4.0 Hydrogen sulfide as a potential therapy against COVID-19
infection
There is currently no drug for effective treatment of COVID-19.
Investigations into the search for drugs to combat COVID-19 are
underway. In the meantime, remdesivir, an orphan antiviral drug
originally developed to treat Ebola virus disease and Marburg virus
infections (via inhibition of the viral RNA-dependent RNA polymerase),
is the only drug approved by United States Food and Drug Administration
(FDA) for the treatment of COVID-19 in symptomatic patients (Wang et
al., 2020). This antiviral drug is administered along with convalescent
plasma. In addition to remdesivir, a host of vaccine candidates have
been approved and distributed for global use to curb the spread of SARS
CoV-2.
