Common Diabetes Drug Shows Promise as Treatment for COVID-19 Lung Inflammation

Metformin is a widely prescribed blood sugar-lowering drug. It is often used as an early therapy (in combination with diet and lifestyle changes) for type 2 diabetes, which afflicts more than 34 million Americans.

Metformin works by lowering glucose production in the liver, reducing blood sugar levels that, in turn, improve the body’s response to insulin. But scientists have also noted that metformin possesses anti-inflammatory properties, though the basis for this activity was not known.

In a study published in the journal Immunity, a multi-institution team led by researchers at University of California San Diego School of Medicine identified the molecular mechanism for the anti-inflammatory activity of metformin and, in mouse studies, found that metformin prevents pulmonary or lung inflammation in animals infected with SARS-CoV-2, the virus that causes COVID-19.
