Sequential monotherapy of hypertension.
In most cases, the antihypertensive therapy for an individual patient is selected through a process of trial and error. This study determined if, by treating each hypertensive patient sequentially, with six antihypertensive drugs, one from each of the major classes, one could decide on the best possible drug for control of hypertension. In a randomized open-label crossover study, 19 patients (16 male and 3 female), 28-70 years of age with a sitting diastolic blood pressure of 95-110 mm Hg were given atenolol, captopril, clonidine, indapamide, prazosin, and verapamil in a sequential manner. Each drug was started at the minimum recommended or lower dose and titrated upwards every 2 weeks, if well tolerated, until blood pressure was controlled (diastolic BP < 90 mm Hg). If blood pressure was controlled, the drug was continued for another 2 weeks. A washout period of at least 2 weeks was allowed between drugs. Both systolic and diastolic blood pressures were reduced significantly with all of the six drugs. In 18 of the 19 patients, blood pressure was controlled with at least one of six drugs, frequently with the lowest dose. The authors conclude that if hypertension is not controlled with the lowest recommended dose of a drug, other antihypertensive drugs should be tried sequentially rather than increasing the dose or adding a second drug.
