As Glenmark Pharmaceuticals launched antiviral drug Favipiravir for the treatment of mild to moderate COVID-19 cases, medical experts on Saturday cautioned against seeing it as a “magic bullet” to treat the deadly virus but said it will be helpful as it can be orally administered and reduce viral load.

They said the drug’s real efficacy would be known in the coming months.

Glenmark Pharmaceuticals said it has launched antiviral drug Favipiravir, under the brand name FabiFlu, for the treatment of patients with mild to moderate COVID-19 at a price of about Rs 103 per tablet.

FabiFlu is the first oral Favipiravir-approved medication in India for the treatment of COVID-19, it said in a statement.

“This drug was already being used in Japan for influenza. They have been using it in COVID-19 patients also. Even China was using it and Russia had also given permission in May to use it. Antiviral drugs like Remdesivir and Favipiravir are not specific to COVID-19 but were being used for influenza,” said Dr Vikas Maurya, Director, Department of Pulmonology and Sleep Disorders, Fortis Hospital, Shalimar Bagh.

He said studies found that there was some benefit of Favipiravir in COVID-19 treatment and that is why it has now been launched in India as well.

Dr Maurya said with COVID-19 cases rising, the launching of the drug comes as a relief.
