WASHINGTON (AP) — Drugmaker Merck has asked U.S. regulators to authorize its promising antiviral pill against COVID-19, setting the stage for a decision within weeks.

If cleared by the Food and Drug Administration, it would be the first pill shown to treat COVID-19, adding a new, easy-to-use weapon to the world’s arsenal against the pandemic.

The FDA will scrutinize company data on the drug’s safety and effectiveness before rendering a decision.

All COVID-19 drugs now authorized by the FDA require an IV or injection.
