Hypertensive crises encompass a spectrum of clinical situations that have in common severely elevated blood pressure (dBP > 130 mmHg), together with target organ damage, the central nervous system, cardiovascular system and/or the renal system and the possibility of irreversible organ damage. It is important that the blood pressure is lowered not too abruptly, but smoothly. Excessive reductions in pressure may precipitate on coronary, cerebral or renal ischemia. Several parenteral antihypertensive agents are recommended and the choice for the antihypertensive agents depends on the cause for the hypertensive crisis, the organ damage, severity of elevated blood pressure and the patient´s usual blood pressure before the hypertensive crisis.
