What is dexamethasone?
It is a
steroid
that is used to
reduce inflammation by mimicking anti-inflammatory hormones
produced by the body.
This therapy is approved by
the main regulatory agencies, FDA and EMA, against covid-19 in those forms that require hospitalization.
This medicine from the family of corticosteroids is used to treat the infection from the beginning, as Patricia Fanlo, coordinator of the Group of Systemic Autoimmune Diseases (GEAS) of the Spanish Society of Internal Medicine (SEMI), points out. , Spain incorporated it as one of the
essential drugs against covid-19

first treatment shown to reduce mortality
in COVID-19 patients who require oxygen or respiratory assistance. "
