Drug interactions
Betamethasone + Enalapril
For healthcare professionals — reference only. This page is a brief summary, not medical advice and not a substitute for official labeling or clinical judgement. Always verify before prescribing or dispensing.
Overview
Systemic corticosteroids may reduce the antihypertensive effect of enalapril via sodium and water retention, potentially increasing blood pressure and fluid retention.
Mechanism of action
Pharmacodynamic antagonism: glucocorticoid/mineralocorticoid effects increase sodium reabsorption and vascular responsiveness, counteracting RAAS blockade.
Clinical management
Monitor BP and volume status; adjust antihypertensive regimen if BP rises; use the lowest effective corticosteroid dose/duration; monitor electrolytes (Na+, K+) in at-risk patients.
