Britain has become the first country in the world to approve pills against the coronavirus. Molnupiravir is an experimental antiviral drug developed to treat influenza. Clinical trials have shown that it roughly halves the risk of hospitalization and death from the coronavirus.
The British Medicines and Healthcare products Regulatory Agency (MHRA) approved the drugs. Health Secretary Sajid Javid called the day “historic for the country.” According to him, the treatment will “change the game” for patients with weakened immune systems.
The pills will be given twice a day to the most vulnerable patients who have recently been diagnosed with the disease.
Molnupiravir was jointly developed by the American pharmaceutical companies Merck Sharp & Dohme and Ridgeback Biotherapeutics. The drug will be produced in the form of tablets for oral use rather than administered intravenously.
The drug works by blocking an enzyme the virus needs to create its DNA. This should prevent it from multiplying and reduce the risk of a severe course of the disease.
Merck says the pills will also be effective against new strains of the coronavirus that may emerge in the future. The MHRA recommended molnupiravir for patients with moderate and mild symptoms, those with underlying conditions, excess weight, diabetes or heart problems, as well as elderly people.
The head of the MHRA said the pill is “another therapeutic agent that adds to our arsenal in the fight against the coronavirus.”

Britain has already ordered 480,000 courses of the drug, which are expected to arrive by the end of 2021. According to experts, the pills have enormous potential in the fight against the pandemic.
The pills are easy to produce, transport, store and administer. This makes them a particularly attractive option for countries with low and middle incomes, weak infrastructure and limited vaccine supplies.

Based on data from 775 patients who took part in the study and took molnupiravir, the following was established:
The company published these data in an official press release, but independent reviews have not yet confirmed them.
Based on the trial results, the pill must be taken in the early stages of symptoms to be effective. Previously, manufacturers tried to conduct another study involving patients hospitalized with severe coronavirus symptoms, but it had to be stopped because the drug did not produce noticeable results.
Merck was the first company to report trial results for a coronavirus pill. Other pharmaceutical companies are also working on similar developments.
For example, Pfizer has started studies of two different antiviral pills. Swiss company Roche is also developing such drugs.
