Abstract
Renin-angiotensin-aldosterone system (RAAS) is primarily involved with pathological mechanism of developing hypertensive emergencies. However, none of clinical practice guidelines mention RAAS blockers for the treatment of hypertensive emergencies. A 44 year-old woman presented with severe hypertension, brain stem posterior reversible encephalopathy syndrome and severe acute kidney injury (AKI). We started anti-hypertensive therapy with continuous intravenous nitroglycerin and oral calcium channel blocker (CCB) and spironolactone. Since severe AKI persisted despite this therapy, we administered losartan potassium, which resulted in improvement in her blood pressure and creatinine. Clinical course of our patient suggests that timely initiation of ARB and spironolactone for hypertensive emergencies could be beneficial in terms of blood pressure control and for protection of target organs from this condition.
