Although there is no clinical study that provides any evidence of how much reduction in blood pressure is considered to be optimal,
many have suggested a target systolic blood pressure of 140-150 mmHg and diastolic blood pressure of 90-100 mmHg.
In pregnant women who have experienced target organ damage,
it is suggested to reduce the blood pressure to less than 140/90 mmHg until it reaches 120 and 80 mmHg.
