1 Hypertension in West Indians and Africans is common and has an unacceptably high mortality in the younger patients. 2 Fifty-three patients received labetalol (a combined alpha- and beta-adrenoreceptor antagonist) as part of an open evaluation of its anti-hypertensive effect. Ten non-caucasian patients were included. 3 Significant reductions in systolic and diastolic pressures were obtained in the caucasian patients, the African and West Indian patients remaining refractory to therapy.
