For instance, spirapril (an ACE inhibitor antihypertensive drug used to treat hypertension; DrugBank), lisinopril (an ACE inhibitor used to treat hypertension, heart failure, and acute myocardial infarction; DrugBank), and captopril (an ACE inhibitor used for the management of essential or renovascular hypertension, congestive heart failure, left ventricular dysfunction following myocardial infarction, and nephropathy; DrugBank) seems to be suitable candidates as repurposing drugs against COVID-2019 [40]. Here, ACE is linked to congestive heart failure.
