Zydus Cadila on Friday announced it has received restricted Emergency Use Approval from the Drug Controller General of India (DCGI) for the use of antiviral 'Virafin' in treating moderate Covid-19 infection in adults.

The single dose subcutaneous regimen of the anti-viral drug reduced the need for supplemental oxygen, indicating that it was able to control respiratory distress and failure -- one of the major challenges in treating Covid-19, according to results of a multicentric trial conducted in 20-25 centres across India.
