Differing Responses in Blood Pressure Over 24 Hours in Normotensive Women Receiving Oral or Transdermal Estrogen Replacement Therapy

Abstract

Transdermal ERT was associated with a reduction in mean ambulatory BP, whereas oral treatment did not alter BP. Although the overall effect of estrogen was to lower BP, individual responses were variable, and BP increased in more than one-third of the women on either treatment. Therefore, long-term monitoring of ambulatory measurements may be required.
