There is no RCT evidence demonstrating that antihypertensive drugs reduce mortality or morbidity in patients with hypertensive emergencies .
Furthermore , there is insufficient RCT evidence to determine which drug or drug class is most effective in reducing mortality and morbidity .
There were some minor differences in the degree of blood pressure lowering when one class of antihypertensive drug is compared to another .
However , the clinical significance is unknown .
Hypertensive emergencies occur when high blood pressure is associated with the presence of acute end-organ damage , such as hypertensive encephalopathy .
There is controversy as to when and which antihypertensive drugs to use in these situations .
A randomized comparison of nifedipine and sodium nitroprusside in severe hypertension.
We r and omized patients with severe hypertension in the Medical Intensive Care Unit to a treatment regimen of oral nifedipine or intravenous nitroprusside . Patients treated with nifedipine achieved a sustained reduction in diastolic blood pressure to less than or equal to 120 mm Hg in an average of less than five hours . Patients treated with nitroprusside achieved a similar reduction in 14 hours ( p less than 0.05 ) . Treatment with nifedipine was less expensive and required less time in the ICU than treatment with nitroprusside and was accompanied by no associated increase in morbidity or mortality . Oral nifedipine can be used as an alternative to intravenous nitroprusside in severe uncomplicated hypertension
