[Randomized, comparative study on the treatment of moderate arterial hypertension during pregnancy: methyldopa, acebutolol, labetalol].
The aim of this prospective, monocentric, opened study and with random order for antihypertensive sequence was to compare a betablocker with sympathomimetic activity (ACE) and an alphabetablocker (LAB) to the gold standard treatment (MD) in moderate HDP (BP greater than 90 mmHg). This study (January 1984 to December 1985) includes 63 women, mean age 28.2 years, divided into three comparable subgroups (age, parity, risk factors and initial level of SBP/DBP). Initial doses are 500 mg/bid (MD), and 400 mg/bid (ACE, LAB) and optimal dosages could not be respectively more than 1500 mg/bid (MD) or 1200 mg/bid (ACE, LAB). Usual criteria for maternal and foetal care are taken into account. The chi 2 test, the Student "t" test and the Kruskall Wallis test were used for statistical analysis. The results show: 1--A similar antihypertensive effect for MD and LAB, but significantly less for ACE (initial PAD-37th week PAD: MD +/- 18.8 +/- 2; LAB = -17.9 +/- 3; ACE = - 8.2 +/- 2.7 mmHg, p less than 0.02; 2--A more frequent adjustment of daily dosage with MD (n = 15) than with ACE (n = 10) or LAB (n = 7); 3--The absence of any significant difference for uricemia level, platelet counts, foetal cardiac rythm, and occurrence of pre-eclampsia (MD = 4; ACE = 3; LAB = 4; 4--An equivalent birth-weight (MD = 3110 +/- 628 g; ACE = 3115 +/- 645.(ABSTRACT TRUNCATED AT 250 WORDS)
