Hypertensive urgency, also called accelerated hypertension, involves a diastolic blood pressure of greater than 130mm, and may have exudates and hemorrhages present. It does not, however, demonstrate the end-organ failure characteristic of malignant hypertension, but still needs immediate attention.

Treatment

Various antihypertensive agents are effective. In comparisons of nifedipine and clonidine, clonidine may cause more sedation[1][2]. Repeated doses of clonidine is not needed.[3]
