Abstract
PURPOSE OF REVIEW: Acute drug-induced hypertension, sympathomimetic toxicity, and other hyperadrenergic states can be caused by both xenobiotic toxicity and withdrawal. This manuscript is a selective review of the recent literature regarding pharmacologic causes of hypertensive emergencies and other hyperadrenergic states. RECENT FINDINGS: We will discuss designer stimulants, alpha2 and baclofen agonist withdrawal, and the clinical entity known as posterior reversible encephalopathy syndrome (PRES). Additionally, we examine the controversial "unopposed alpha" phenomenon which may result from use of beta-adrenergic antagonist in the presence of stimulant toxicity. These topics encompass clinical situations and disease entities that are increasingly encountered and are often either unanticipated or under-recognized.
