Abstract

Data on substituting one antihypertensive medication with the proper dose of another antihypertensive medication, in certain medical conditions, are scarce. Herein, we present the results of replacing angiotensin-converting enzyme inhibitors (ACEIs) or angiotensin receptor blockers (ARBs) with the calcium channel blocker (CCB) amlodipine, with or without the alpha- and beta-blocker carvedilol, to control high blood pressure in patients with coronavirus disease 2019 (COVID-19). Iranian hypertensive patients with COVID-19 and a history of taking ACEI or ARB were randomized to “continue” and “change” groups. The continue group comprised patients who continued using their previous antihypertensive medication regimen as normal, whereas patients in the change group had their antihypertensive drugs changed to the CCB amlodipine, with or without the alpha- and beta-blocker carvedilol, based on their response to amlodipine. Patients’ blood pressures were measured for 8 days following their recruitment. A total of 31 and 33 patients were randomly allocated to the ACEI/ARB continue and ACEI/ARB change groups, respectively. No significant deviations were seen in patients’ systolic blood pressure by substituting an ACEI/ARB agent with the CCB amlodipine, with or without the alpha- and beta-blocker carvedilol. Moreover, the change group had a more balanced systolic blood pressure (ie, 110–130 mmHg) compared with the continue group (ie, 111.5–140.0 mmHg) throughout their hospitalization period. During their hospitalization, the blood pressure of the change group was well controlled with the proposed equivalent doses. Further investigations of the proposed equivalent doses in larger randomized clinical trials, populations other than Iranian COVID-19 patients, and extended duration are encouraged (clinical trial registration ID: IRCT20151113025025N3). © 2023, The American College of Clinical Pharmacology.
