Just a month ago, the doctors fighting against Covid19 all over the world found a magic drug hydroxychloroquine in the treatment of Covid19. Though this Chloroquine-derivative was known to every doctor for its role in Rheumatoid arthritis and SLE, the action of it in Covid19 was newly detected. The hope and hype increased after the USA purchased 29 million doses of Hydroxychloroquine from India after a bitter exchange of words. Now after the Covid19 death toll of the USA reaching almost 64,000, the USA loses faith in this drug and is looking for a potent antiviral drug. Remdesivir is the most trusted drug at this critical juncture. Favipiravir, Lopinavir, Ritonavir are the other antiviral drugs tried in many parts of the world. Hydroxychloroquine is now a second-line drug in the fight against Covid19. But its need for prophylaxis against Covid19 can not be denied.
