Objective: Determine the efficacy and effectiveness of the use of programmed liberate nifedipine on microgranules in the treatment of the hypertensive disease in pregnancy. Methods: Sixty two serial patients were admitted with hypertensive disease in pregnancy with age gestacional superior than 20 weeks, were they assigned to receive 30 or 60 mg of programmed liberate nifedipine on micro-granules in the morning with the final objective from obtaining an effective control of the blood pressure (systolic blood pressure ≤ 120 and diastolic blood pressure ≤ 80 mmHg), quantified with a mercury sphygmomanometer. Cases with history of heart inadequacy and that they received antihypertensive treatment during the course of the current pregnancy they were excluded. The time required to obtain the effective control of the blood pressure was quantified and the episodes of hypertensive crisis were identified with the treatment as well as the adverse effects in the mother or the fetus. Results: The age of the patients was of 28.2±7.8 years, weigh 75.1±13.2 kilos, height 162.3±7.0 cm, Index of corporal mass 28.5 ± 4.6 kg/m2. The reductions of the arterial pressures were: decubitus. Systolic blood pressure (of 140.0±8.1 at 119.0±8.8 mmHg. P <0.0001), diastolic blood pressure (of 89.7±7.7 at 72.7±7.8 mmHg. P <0.0001), heart rate (of 82.2±10 to 81.3±10 beats/min. P = 0.31). Seated Systolic blood pressure (of 140.3±6.8 at 117.9±8.9 mmHg. P <0.0001), diastolic blood pressure (of 88.6±8.1 at 71.5±8.5 mmHg. P <0.0001), heart rate (of 84.2±9,0 to 82.3±9.4 beats/min. P = 0.12). Of foot. Systolic blood pressure (of 141.7±6.76 at 118.3±8.5 mmHg. P <0.0001), diastolic blood pressure (of 88.9±6.9 at 72.6±8.6 mmHg. P <0.0001), heart rate (of 84.8±9.2 to 83.6±9.6 beats/min. P = 0.24). The blood pressure control was achievement in an average of 6 weeks of treatment with programmed liberate nifedipine on micro-granules. A new event of hypertensive crisis wasn´t happens, neither adverse effect didn’t see in the mother or the fetus after drug administration. Conclusion: The programmed liberate nifedipine on micro-granules achieved an effective control of the blood pressure, demonstrating to be safe and effective in the patients with the hypertensive disease in pregnancy.
