Labetalol, a new alpha- and beta-adrenoreceptor blocking agent, in hypertension.
1Labetalol is a new compound with antagonistic effects at both alpha- and beta-adrenoreceptor sites. 2 When given to 12 hypertensive patients at an average daily dosage of 273 mg for 7 months statistically significant reductions (compared with pretreatment values) in recumbent and standing blood pressure were observed. 3 Treatment has to be withdrawn in one patient because of vivid dreams, and dosage was reduced in one patient because of dizziness. Otherwise no side-effects of importance were noted. 4 It can therefore be concluded that labetalol offers a useful anti-hypertensive effect and that this compound is well tolerated.
