The UK medicines regulator has become the first in the world to approve an oral antiviral pill for Covid in a move that paves the way for tens of thousands of vulnerable patients to receive the treatment from this winter.

Nearly half a million doses of molnupiravir, a pill that can be taken twice daily at home, are due for delivery from mid-November and will be given as a priority to elderly Covid patients and those with particular vulnerabilities, such as weakened immune systems. The drug will initially be given to patients through a national study run by the NHS.

Prof Peter Horby, the co-leader of the groundbreaking Recovery trial of Covid treatments at the University of Oxford, said the decision by the Medicines and Healthcare products Regulatory Agency (MHRA) was very welcome and amounted to a watershed moment in tackling the pandemic.

The MHRA said on Thursday that the drug developed by Ridgeback Biotherapeutics and Merck Sharp and Dohme (MSD), was safe and effective at reducing the risk of hospitalisation and death in people with mild to moderate Covid who are at increased risk of developing severe disease.

The health secretary, Sajid Javid, said the decision marked a “historic day”, adding “the UK is now the first country in the world to approve an antiviral that can be taken at home for Covid-19. This will be a gamechanger for the most vulnerable and the immunosuppressed, who will soon be able to receive the groundbreaking treatment.  ...

Molnupiravir interferes with the virus’s ability to replicate, meaning it is less able to multiply and reach high enough levels in the respiratory system to cause severe disease. Because the drug is most effective when given in the early stages of infection, the MHRA recommends it is used as soon as possible after a positive test for Covid and within five days of symptoms appearing. ”  ......
