Drug treatment of hypertensive urgencies and emergencies.
Although systemic hypertension is a common clinical condition, hypertensive emergencies are distinctly unusual in clinical practice. There are some situations, however, that qualify as hypertensive emergencies or urgencies. It is important, therefore, to diagnose these conditions because immediate treatment of severe hypertension is indicated. The diagnosis of hypertensive emergencies depends on the consideration of the clinical manifestations as well as the absolute level of blood pressure. Depending on the target organ that is affected, manifestations of hypertensive emergencies can be quite profound, yet variable. Thus, the physician has to make an accurate clinical diagnosis properly to render appropriate therapy. Fortunately, effective drug therapy is available to decrease blood pressure quickly in hypertensive emergencies. Physicians should be familiar with the pharmacologic and clinical actions of drugs that are used in the treatment of hypertensive emergencies. With proper clinical diagnosis, hypertensive emergencies can be treated successfully and the complications can be prevented with timely intervention. This review discusses the treatment of hypertensive emergencies in general and the therapeutic role of fenoldopam in particular.
