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.
