Treatment for chronic hypertension in pregnancy with labetalol showed no significant differences in maternal or neonatal outcomes compared with treatment with nifedipine.
Treatment for chronic hypertension in pregnancy with labetalol showed no significant differences in maternal or neonatal outcomes, compared with treatment with nifedipine, new research indicates.) trial showed that treating mild chronic hypertension was better than delaying treatment until severe hypertension developed, but still unclear was whether, or to what extent, the choice of first-line treatment affected outcomes.
The primary outcome was occurrence of superimposed preeclampsia with severe features; preterm birth before 35 weeks of gestation; placental abruption; or fetal or neonatal death. The key secondary outcome was a small-for-gestational age neonate. Researchers also compared adverse effects between groups.The primary outcome occurred in 30.1% in the labetalol group; 31.2% in the nifedipine group; and 37% in the standard care group.
There were no significant differences in numbers of small-for-gestational age neonates or serious adverse events between those who received labetalol and those using nifedipine. "Thus, labetalol compared with nifedipine appeared to have fewer adverse events and to be better tolerated," the authors write. They note that labetalol, a third-generation mixed alpha- and beta-adrenergic antagonist, is contraindicated for those who have obstructive pulmonary disease and nifedipine, a dihydropyridine calcium channel blocker, is contraindicated in people with tachycardia.
