Captopril (DrugBank DB01197) and quinapril (DrugBank DB00881) belong to angiotensin-converting enzyme (ACE) inhibitors, which are widely used for the treatment of hypertension and have been associated with reduced risks of COVID-19 (Hippisley-Cox et al., 2020; Tepasse et al., 2022). This evidence concerns the gene ACE and COVID-19.
