I read an article on the BBC which said that corticosteroids where used to treat Covid-19 patients in India. Later they changed the word corticosteroids into steroids and they added that they were used to reduce lung inflammation. I didn't know what corticosteroids were so I checked on Wikipedia, where I also found this article, which repeats from another source that corticosteroids where used to treat Covid-19 patients.
As far as I understood corticosteroids are immunosuppressors, therefore I cannot understand why they are used to threat a viral infection. Isn't there a more appropriated treatment to reduce lung inflammation in such cases?
There is another question about corticosteroids and covid-19, but it asks something different: Why do corticosteroids harm COVID-19 patients?
