Meanwhile, the use of methyldopa which is included in the central sympatholytic group was 17 respondents (28%). In the single therapy type study, 59 prescriptions (100%) used nifedipine or methyldopa. Pregnant women are encouraged to routinely conduct antenatal care checks at the hospital every month.
