Are statins beneficial for the treatment of SARS-CoV-2 infection?

Abstract

Novel coronavirus disease 2019 (COVID-19) is a highly infectious, rapidly spreading viral disease and has emerged as a public health emergency of international concern. As of this time, there are no specific antiviral therapies available for the treatment of COVID-19. However, it is possible that some existing drugs, usually used for other conditions, may have some benefits. Statins have been widely reported to exert antiviral activity against many enveloped viruses by inhibiting the cholesterol biosynthesis pathway. Cholesterol likewise contributes to the coronavirus's life cycle, including viral entry, fusion and budding. In addition, statins have been ascribed beneficial anti-inflammatory, immunomodulatory effects and promote haemodynamic stability. Therefore, statins, which are cholesterol-lowering drugs with anti-inflammatory, immunomodulatory and antiviral properties, may play a role in SARS-CoV-2 therapy. The aim of the present minireview was to delineate the potential beneficial therapeutic effects of statins in treating SARS-CoV-2 infections. Nevertheless, large, randomised trials are needed to confirm the beneficial effects and safety profile of the statins in patients with SARS-CoV-2.
