Investigating the Relationship Between Acne and Vasodilatory Medications in a Hospital-Wide Adult Population.

ABSTRACT

Acne vulgaris is a common chronic dermatological condition characterized by obstruction and inflammation of pilosebaceous units. Recent research on a different dermatologic condition has demonstrated that the use of vasodilatory medications is associated with a decreased relative risk of rosacea. This finding is significant due to the overlapping inflammatory pathways involved in rosacea and acne. Herein, a retrospective cohort study was designed to determine the correlation between vasodilator usage and the risk of developing acne within 5 years, contrasting it with thiazide diuretics, chosen as a control due to its non-vasodilatory antihypertensive mechanism and availability of data. Angiotensin-converting enzyme (ACE) inhibitors (RR, 0.775; 95% CI, 0.727-0.826; P<0.05), angiotensin receptor blockers (ARBs) (RR, 0.739; 95% CI, 0.685-0.797; P<0.05), beta-blockers (BB) (RR, 0.829; 95% CI, 0.777-0.885; P<0.05), and calcium channel blockers (CCB) usage (RR, 0.821, 95% CI, 0.773-0.873; P<0.05) were associated with a significantly lower risk of developing acne within 5 years of initiating therapy compared to thiazide diuretics. It is unclear if thiazide diuretics are more likely to cause acne within the adult population or if vasodilators are protective against the development of acne. Finding mechanisms and therapeutics that lower the risk of developing acne is of significant public health interest, and this study provides a step toward this endeavor. Further research is required to uncover the underlying mechanisms for this reduction in the development of acne.  J Drugs Dermatol. 2024;23(6)446-449.     doi10.36849/JDD.8362.
