Treatment of hypertension: Insights from the JNC-VI report

The sixth report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC-VI) provides updated guidelines for the treatment of hypertension. Antihypertensive drug therapy may be initiated either after a trial of lifestyle modifications or immediately after the diagnosis is made, depending on the patient's other cardiovascular risk factors and the presence of clinical cardiovascular disease. In general, therapy may begin with diuretics or beta-adrenergic blockers in patients under age 65, unless a concomitant condition warrants another, more tailored choice. Low dosages should be used initially but if the blood pressure is not successfully reduced to 140/90 mm Hg or below, another drug should be added or should replace the initial choice. General principles of therapy include the use of once-a-day formulations and combination drugs as well as cost considerations.
