Inhaled budesonide is a form of cortisone (corticosteroid), which was first approved in 1994. It is used globally for treating asthma and in some countries, it is also approved for treating chronic obstructive pulmonary disease (COPD).
Inhaled budesonide exerts powerful anti-inflammatory effects on bronchial and lung tissues. Researchers have also found that it directly inhibits replication of the SARS-CoV-2 virus, amongst its other mechanisms of action against COVID-19.
The origin of the idea to use inhaled budesonide for treating COVID-19 is unclear. In March 2020, early during the pandemic, a clinical trial using inhaled budesonide was registered at HÔPITAUX DE PARIS in France. In parallel, researchers Dr. Dan Nocolau of QUT in Brisbane, Australia, and Dr. Moa Bafahdel of Oxford University in the UK were surprised to notice that asthma and COPD patients using inhaled budesonide were less likely to become infected with SARS-CoV-2 or to develop COVID-19. They theorized that the regular use of inhaled budesonide by these patients was providing a protective effect against COVID-19.
A clinical trial at the University of Oxford enrolled 1,700 early COVID-19 patients. The study results clearly demonstrate the potential for inhaled budesonide to treat early COVID-19 in non-hospitalized patients. In April 2021 the British National Health Service published an interim position statement allowing physicians to prescribe inhaled budesonide to COVID-19 patients aged over 65 years or over 50 years if they suffered from a long-term health condition.
In May 2021 the Ministry of Health, Government of India added inhaled budesonide to its Clinical Management Protocol for COVID-19 in adults. They recommended prescribing it to patients who have persistent symptoms of fever and/or cough beyond 5 days from onset of disease. Their recommended dosing is 800 micrograms twice a day for 5 to 7 days.

Inhaled Budesonide's Anti-COVID Properties
- Downregulates gene expression of ACE2, the SARS-CoV-2 virus receptor on human cells
- Downregulates levels of TMPRSS2, which aids SARS-CoV-2 spike protein binding to ACE2
- Inhibits SARS-CoV-2 replication
- Suppresses excessive Type I interferon
A clinical trial of inhaled budesonide in high-risk COVID-19 patients showed significantly faster recovery times, reduced hospitalizations and lower death rates.

Inhaled Steroid For Early COVID-19: Increased Clinical Recovery And Decreased Persistent Symptoms?
Inhaled Budesonide, a steroid medication, for the treatment of early COVID-19. This new research study published in Lancet found that in early COVID-19 inhaled Budesonide may increase the probability of clinical recovery, decrease the risk for decompensation, and prevent persistence of symptoms (decrease the potential for Long Haulers?)
Study – Inhaled budesonide in the treatment of early COVID-19 (STOIC)
Researchers in UK studied the effect of inhaled budesonide in outpatient setting for mild COVID patients. Researchers found out that the early use of inhaled budesnoid reduces the likelihood of needing urgent medical care and reduces time to recovery after early COVID.

An anti-inflammatory medicine commonly used for asthma has been found to shorten the recovery time of COVID-19 patients and could potentially be used to treat patients early in their illness at home.
