The efficacy and safety of labetalol therapy were evaluated in 20 patients 60 years and older with isolated systolic or diastolic hypertension and 19 patients aged younger than 60 years with diastolic hypertension. After a two‐week placebo washout period, labetalol was titrated for up to four weeks (100–400 mg bid) until blood pressure control was achieved (standing systolic < 160 mm Hg or ≥ 10% reduction from baseline, and standing diastolic < 90 mm Hg or a decrease of 10 mm Hg from baseline). Mean decreases in standing systolic and diastolic blood pressure from baseline were statistically significant for both age groups (≥60 years, −23/−13; <60 years, −18/−12, P < .01). Control criteria were met in 18 (90%) older and 15 (79%) younger patients who then entered a four‐week maintenance period. Sixteen (80%) of the older patients and six (32%) of the younger patients maintained blood pressure control on 200 mg or less of labetalol bid (P < .05). Three patients, two of whom withdrew from the study, were judged to have experienced adverse events that were drug related. It was concluded that labetalol was effective and well‐tolerated antihypertensive therapy in both elderly and younger patients. In addition, significantly less medication was required to achieve blood pressure control in the elderly. 1987 American College of Clinical Pharmacology
