Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 50 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Triple (Participant, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Study Start Date : August 2011
Actual Primary Completion Date : February 2012
Actual Study Completion Date : May 2012

Arm Intervention/treatment
Experimental: Methyldopa
In case group, 25 patients, under treatment, using Methyldopa for 7 days, received 500 mgs of Methyldopa in its oral form per day and in control group, participants received placebo for 7 days.
Drug: Methyldopa
Placebo Comparator: placebo Drug: Placebo

Primary Outcome Measures :
  1. Doppler indices [ Time Frame: 7 days ]

    In case group, 25 patients, under treatment, using Methyldopa for 7 days, received 500 mgs of Methyldopa in its oral form per day and in control group, participants received placebo for 7 days.Before and after drug use, Doppler ultrasound test was done by a radiology specialist not informed of patients grouping. Also, pulsatility index, resistance index, systolic/diastolic blood flow ratios of uterine artery, umbilical artery and middle-cerebral artery were evaluated. Registered for all patients, age, BMI, gestational week and the number of pregnancies were among other examined variables.

    Doppler indices of examined arteries in studied groups were evaluated by color Doppler ultrasound of model "Hitachi 3/6 MHz".
