Evolving the Role of Black Race in Hypertension Therapeutics.

Black race has been used to guide antihypertensive drug selection for Black patients based on predominant between race (same drug) and intra-race (different drugs) blood pressure (BP) response patterns. Accordingly, thiazide diuretics and calcium antagonists have been recommended over renin-angiotensin system (RAS) inhibitors (angiotensin-receptor blockers, angiotensin-converting enzyme inhibitors) and beta blockers for Black patients. Current antihypertensive drug prescribing reflects historical guidance as calcium antagonists and thiazide diuretics are prescribed more and RAS blockers less in Black than White patients. Hypertension control rates in Blacks, lag those for Whites despite their greater use of combination drug therapy and lesser use of monotherapy. This is also true across drug regimens containing any of the 4 recommended classes for initial therapy as well as for evidence-based combination drug therapy (calcium antagonist or thiazide diuretic + RAS blocker) regimens for which there is no known racial disparity in BP response. Current recommendations acknowledge the need for combination drug therapy in most, especially in Black patients. One exemplary comprehensive hypertension control program achieved >80% control rates in Black and White patients with minimal racial disparity while utilizing a race-agnostic therapeutic algorithm. Black patients manifest robust, if not outsized, BP responses to diet/lifestyle modifications. Importantly, race neither appears to be a necessary nor sufficient consideration for the selection of effective drug therapy. Accordingly, we urge the initiation of adequately intense race-agnostic drug therapy coupled with greater emphasis on diet/lifestyle modifications for Black patients as the cornerstone of a race-informed approach to hypertension therapeutics.
