First anti-viral pill to treat Covid-19 approved for use

Molnupiravir can now be taken by people testing positive for coronavirus

A pill to treat Covid-19 that you can take at home has been approved for use in the UK, the first time an anti-viral drug has been approved for home use anywhere in the world.

Molnupiravir is an anti-viral treatment for people who have had a positive Covid test and have at least one risk factor for developing severe illness, such as obesity, being over the age of 60, diabetes or heart disease.

The UK’s Medicines and Healthcare products Regulatory Agency (MHRA) has approved the drug's use, saying it is safe and effective at reducing the risk of hospital admission and death in people with mild to moderate Covid but who are at extra risk from the virus.

The Government announced last month that it had secured 480,000 courses of molnupiravir after a study found it cut the rate of hospital admission and death by 50% in mild-to-moderately ill patients who had at least one risk factor for the disease.

How does anti-viral Molnupiravir work against Covid?

The drug, from Ridgeback Biotherapeutics and Merck Sharp & Dohme (MSD), works by interfering with the virus’s replication.

It prevents the virus from multiplying, keeping levels low in the body and therefore reducing the severity of the disease.

The MHRA said the drug should be taken as soon as possible following a positive Covid-19 test and within the first five days.

In the study, the tablet was given twice a day to patients recently diagnosed with coronavirus.

The first country in the world to approve an anti-viral treatment

Health and Social Care Secretary, Sajid Javid, said: “Today is a historic day for our country, as the UK is now the first country in the world to approve an anti-viral 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 ground-breaking treatment.

“We are working at pace across the Government and with the NHS to set out plans to deploy molnupiravir to patients through a national study as soon as possible

“This antiviral will be an excellent addition to our armoury against Covid-19, and it remains vital everyone comes forward for their life-saving Covid-19 vaccine – particularly those eligible for a booster – to ensure as many people as possible are protected over the coming months.”

"Another therapeutic to add to our armoury against Covid-19"

Dr June Raine, MHRA chief executive, said: “Following a rigorous review of the data by our expert scientists and clinicians, we are satisfied that Lagevrio (molnupiravir) is safe and effective for those at risk of developing severe Covid-19 disease and have granted its approval.

“Lagevrio is another therapeutic to add to our armoury against Covid-19.

“It is also the world’s first approved anti-viral for this disease that can be taken by mouth rather than administered intravenously.

“This is important, because it means it can be administered outside of a hospital setting, before Covid-19 has progressed to a severe stage.

“With no compromises on quality, safety and effectiveness, the public can trust that the MHRA has conducted a robust and thorough assessment of the data.”

Coronavirus FAQs

What is Covid-19?

Covid-19 emerged as a virus in December 2019 as the first cases are reported in Wuhan, China. Scientifically known as SARS-CoV-2, the virus created a global pandemic as it began to spread around the world. Symptoms can range from very mild to severe, causing death in some cases. Some people are completely asymptomatic and do not realise they even have the virus.

Has there been a virus like this before?

The SARS pandemic in 2003 was similar to Covid-19 in that it was also caused by a coronavirus. SARS stands for Severe Acute Respiratory Syndrome. The global outbreak of SARS lasted from 2002-2003, infecting over 8,000 people and killing 774. Covid-19 and SARS are both respiratory illnesses, but SARS was much more deadly and less infectious.

What are the main symptoms?

The NHS say the main Covid-19 symptoms are a high temperature, a new and continuous cough and loss or change to taste of sense or smell. NHS advises people with Covid-19 to take plenty of rest, drink lots of fluids, and take paracetamol for a high temperature.

What was the Government reaction?

The UK Government announced the first of several lockdowns in March 2020. By the end of the month, more than 100 countries around the world introduce full or partial lockdowns, preventing people from going to work, restricting everyday tasks and affecting the livelihoods of billions of people globally.

Which countries have been worst hit?

During the first year of the pandemic, the US recorded the highest number of Covid-19 cases in the world and the most deaths, reporting an unprecedented 100,000 new cases in one day on November 4th 2020. Thousands of new cases were recorded on the same date in India (46,000+), the United Kingdom (22,000+), Brazil (17,000+) and Mexico (5,000+), while Ireland records less than 1,000 (578). Hundreds of other countries also reported a high rate of infection.

How have vaccines fought against Covid-19?

Vaccines began being approved for use across the globe. By January 2021, the UK approved the use of three different vaccines. The Pfizer-BioNtech vaccine, Oxford/AstraZeneca vaccine and the Moderna vaccine are rolled out to the public, with older people and those with greater health concerns getting priority. In April 2022, just under 53 million people had received at least one dose of the vaccine.

What are new Covid variants?

Four new variants of Covid-19 were discovered around the world. Beta was found in South Africa, Gamma in Brazil and Delta in India, while the Alpha variant was first located in Kent, UK. New variants are not likely to make someone more seriously ill than Covid-19 would, but variants like Delta have a higher infection rate, meaning it can be more easily spread.

The Omicron variant was first detected late 2021 in South Africa. Since then, it has become one of the most dominant variants in the world, with its own sub strains - BA.4 and BA.5.
