Ibuprofen is to be tested as a potential treatment for coronavirus.
A clinical trial is now underway by scientists working to see if ibuprofen can help hospital patients who are have the virus.
The study aims to evaluate the reduction in severity and progression of lung injury with three doses of lipid ibuprofen in patients with SARS-CoV-2 infections.
Ibuprofen is an anti-inflammatory as well as a painkiller and now, the team from London's Guy's and St Thomas' hospital and King's College believe the drug could treat breathing difficulties.
The hope is that the cost effective painkiller will reduce the need for ventilators among patients infected with the virus.
But in March, some medical experts warned against using ibuprofen and said it was not recommended for managing coronavirus symptoms, but added those already taking the drug for other conditions should not stop without consulting a doctor.
Paracetamol and ibuprofen can both bring a temperature down and help with flu-like symptoms.
But ibuprofen and other non-steroidal anti-inflammatory drugs (NSAIDs) are not suitable for everyone and can cause side-effects - especially for people with asthma, heart and circulatory problems.
A review by the Commission on Human Medicines determined it was safe to take ibuprofen for coronavirus symptoms.
The BBC reports the new trial, called Liberate, will use a special formulation of ibuprofen rather than the regular pills people may usually buy over the counter.
Some people already take lipid ibuprofen for conditions like arthritis.
If you experience mild coronavirus symptoms, the NHS advises people to use paracetamol first as it has fewer side-effects than ibuprofen.
An estimated 230 participants will be part of the new clinical trial.
