Is baricitinib (Olumiant) being used to treat COVID-19?

Official Answer by Drugs.com

Yes, baricitinib (Olumiant) has FDA approval to treat COVID-19 patients who are

Olumiant has an Emergency Use Authorization (EUA) received from the FDA to treat COVID-19 patients who are:

The original EUA from November 19, 2020 required baricitinib to be used with remdesivir (Veklury) but this requirement has been revoked. This means that baricitinib treatment for COVID-19 can be with or without remdesivir.

The original EUA from November 19, 2020 required baricitinib to be used with remdesivir (Veklury) but this requirement has been revoked.

For a medicine to gain FDA approval, the evidence that shows it is effective has to be at a higher level and a larger quantity, compared to gaining EUA approval.

Baricitinib (Olumiant) is also FDA approved to:

Clinical trials of Baricitinib for COVID-19 Treatment.


The FDA issued the EUA for baricitinib to be used for COVID-19 treatment based on the Phase 3 COV-BARRIER study (NCT04421027). This study was a randomized, double-blind, placebo-controlled study of hospitalized patients which compared baricitinib 4 mg once daily treatment plus standard of care, to placebo treatment with normal standard of care.

The result of this study showed that by day 28:

What to know about baricitinib

Baricitinib is a janus kinase (JAK) inhibitor, which inhibits both the JAK1 and JAK2 subtypes. Janus kinase, and other protein kinases, are enzymes that regulate the biological activity of proteins in our body.

Baricitinib comes in the form of an oral tablet that is already approved by the US Food and Drug Administration (FDA) for the treatment of certain patients with rheumatoid arthritis. Long-term use of the drug is known to be associated with an increased risk of serious infection, lymphoma and other cancers, as well as blood clots. COVID-19 patients, however, won’t be on the treatment long term and will just receive a short, 2-week course of the drug.

Why is baricitinib being investigated for COVID-19?

Baricitinib has anti-inflammatory properties and it is hoped that it could help against the inflammatory cytokine storm seen in severe cases of COVID-19.

Research into baricitinib has also shown that it is also capable of inhibiting NAKs (numb-associated kinases). NAKs are thought to regulate the process by which SARS-CoV-2, the virus that causes COVID-19, infects cells. This process is called clathrin-mediated endocytosis. Baricitinib is expected to be more effective than other similar drugs because it has a particular high affinity for AAK1 (adaptor-associated kinase 1), which is a part of the NAK family of kinases.

How was baricitinib identified as a possible treatment for COVID-19?

In February 2020, the UK-based company BenevolentAI, made use of its artificial intelligence (AI) platform to identify baricitinib as a potential treatment for COVID-19. The company integrates AI technologies into the drug discovery process. Benevolent used its technology to try and identify an existing drug that could stop COVID-19 progressing, inhibit the cytokine storm seen in severe cases and also reduce damage caused by the inflammation associated with the disease.

Can you take ibuprofen on an empty stomach?

Despite popular belief that you have to take ibuprofen with food, you can take ibuprofen on an empty stomach and this will give you faster pain relief than taking it with food. Food increases the time it takes for ibuprofen to be absorbed, although it won't affect how much is absorbed. There is actually no evidence that taking ibuprofen with food prevents gastric irritation – ibuprofen at OTC doses has a low incidence of gastric irritation anyway. Continue reading
