There are no medicines that can cure COVID-19 infection. However, there are treatments that can benefit people who have serious symptoms. The medicines listed below have been recommended by the World Health Organization (WHO) and the United States National Institutes of Health (US NIH). This list will be revised as global treatment guidelines are updated.
Systemic corticosteroids are steroid hormones. They have an anti-inflammatory effect and are given orally or by injection.
Around 50 countries have the medicine either approved or for emergency use authorization for the treatment of COVID-19. Remdesivir was also another medicine that was studied in the Solidarity Trial, which was led by the World Health Organization (WHO).
The RECOVERY (Randomized Evaluation of COVID-19 Therapy) trial found that death from COVID-19 was lower among patients who received dexamethasone than those who received the standard of care without dexamethasone. In addition, the WHO and other researchers conducted a meta-analysis (which is a review of multiple studies) on the use of corticosteroid therapy for COVID-19 and found that these medicines improved survival of those with severe COVID-19 disease.
Remdesivir is an antiviral drug that inhibits the replication of a broad range of viruses.
The WHO does not recommend the use of remdesivir in hospitalized patients with COVID-19, regardless of disease severity. This recommendation was mainly based on the results of the SOLIDARITY trial, which was one of the largest randomized clinical trials to study COVID-19 treatments. Updated information on the use of remdesivir is available in the WHO guidelines.
However, the US NIH does recommend the use of remdesivir among hospitalized patients who require supplemental oxygen. Additional information is available in their guidelines.
IL-6 receptor blockers are a class of medicines that suppress parts of the immune system’s response to COVID-19, which if over activated, can be harmful to the patient.
The WHO and the US NIH have recommended the use of IL-6 receptor blockers tocilizumab or sarilumab for patients with severe or critical COVID-19 infection.
A monoclonal antibody is an antibody made by cloning a unique white blood cell. Antibodies are proteins produced by a specific type of white blood cell, and are involved in protecting the body from bacteria, viruses, and other infectious diseases.
The WHO recommends treatment of COVID-19 with casirivimab and imdevimab among patients who are at highest risk of hospitalization or who are seronegative (without evidence of antibodies against COVID-19).
The US NIH also recommends either a combination of bamlanivimab and etesevimab, or of casirivimab and imdevimab for COVID-19 patients with mild to moderate disease. This is based on studies showing that these monoclonal antibody combinations have the potential to benefit non-hospitalized patients with mild to moderate COVID-19 who are at high risk for disease progression, or in an early stage of infection.
