Renin-angiotensin system inhibitors in management of hypertension during the COVID-19 pandemic.

Renin-angiotensin system inhibitors in management of hypertension during the COVID-19 pandemic. J Physiol Pharmacol. 2020 Apr;71(2): Authors: Dworakowska D, Grossman AB Abstract COVID-19, which is caused by the single-stranded RNA severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2), has introduced significant therapeutic dilemmas in several areas. One of these is concern regarding the use of renin-angiotensin system (RAS) inhibitors. Dysfunction of the RAS has been observed in COVID-19 patients, but whether RAS inhibitors, such as angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin II type-1 receptor blockers (ARBs), are associated with improved or worse clinical outcomes, remains unclear. RAS inhibitors are currently widely used in the treatment of hypertension. Emerging data suggest an increased association and a heightened mortality in patients of COVID-19 with co-morbidities such as hypertension, coronary heart disease, and diabetes mellitus, particularly in the elderly. Therefore, several recently published research papers have focused on the management of hypertension during the COVID-19 pandemic, as this co-morbidity was found to be the most common in patients with coronavirus infections. SARS-CoV-2 viral surface protein is known to attach angiotensin converting enzyme-2 (ACE-2) on the cell membrane to facilitate viral entry into the cytoplasm. While the SARS-CoV-2 viral load remains the highest in upper ...
