The Role Of Ace2 In The Renin-Angiotensin-System: Etiology And Therapy Of Covid-19 From A Pharmaceutical Perspective

Angiotensin-2 converting enzyme (ACE2), a key element of the renin-angiotensin-system (RAS), is not only the direct target of infection by the human SARS-Cov-2 virus but is at the same the root for the complex pathogenetic events of COVID-19. From a pharmaceutical perspective, several established classes of medicines are involved in different phases of the disease. From their known mechanisms of action, a comprehensive understanding of COVID-19 will be hopefully soon delineated. A set of proven medicines is available to cope at least with some of the pathologies involved. To arrive back to normal life, vaccinations and broad consideration of hygienic measures are to be complemented by effective medicines to treat airborne viral infections. Therapeutic schemes based on a comprehensive understanding of the disease will include drug combinations made up from both established drugs as well as novel drugs presently under development.
