Purpose: The new coronavirus, called SARS-CoV-2, is responsible for the recent global pandemic COVID-19. The status of the global pandemic COVID-19 is currently underway, and the virus has caused about 1.11 million deaths. Several SARS-CoV-2 vaccines are in phase 3 clinical trials. Pending the availability of safe and effective vaccines, pharmacological treatments are experimental and aimed at avoiding the most serious complications of the infection. Methods: This article explores and describes the scientific evidence in the literature and the scientific pharmacological and molecular rationale to consider drugs that modulate the reninangiotensin system (RAS) system as therapeutic agents that if administered appropriately can help the host organism to fight SARS-CoV-2 infection. Results: It is known from the 2003 SARS epidemic that the critical receptor for SARS-CoV entry into host cells is the angiotensin-converting enzyme 2 (ACE2), the strain involved in the current SARS-CoV-2 epidemic is similar to the SARS-CoV strain involved in the 2002-2003 SARS epidemic. ACE-2 is part of the RAS system, the modulation of this enzyme could be of therapeutic efficacy. Conclusion: Depending on pharmacological knowledge, and epidemiological evidence in the literature based on current knowledge of the mechanism of penetration of SARS-CoV-2 in cells, and the role of ACE-2 in the inflammatory state of infection, therapeutic treatments that modulate RAS could be a weapon to fight COVID-19 infection.
