In the search for effective COVID-19 treatments, many drugs failed to live up to their early promise.

In October 2021, a global trial investigated an experimental viral drug called molnupiravir, which is branded Lagevrio outside the United States.
The research was led by the pharmaceutical company Merck — known as MSD outside the U.S. and Canada — and Ridgeback Therapeutics.
The scientists found that the drug reduced the risk of hospital admission or death from COVID-19 by approximately 50%.
The World Health Organization (WHO) has now conditionally recommended its use for some people with COVID-19 who have the highest risk of hospital admission.
