Efecto de un preparado en forma de gel de 17 ß estradiol sobre diferentes parámetros hormonales en mujeres menopáusicas / Effects of a 17 ß estradiol gel preparation on different hormonal parameters in menopausal women

ABSTRACT

Different delivery forms of supplemental estrogens may differ in their hormonal effects. The aim of this study was to assess the effects of a daily dose of 2.5 g of 17 ß estradiol transdermal gel, given during four weeks, on hormon levels of six postmenopausal women. At the fourth week we observed a significant increase in estradiol and a dicrease in FSH levels. estrone levels alsa increased but the estradiol-estrone ratio was maintained in values over 1. No changes in SHBG or IGF1 levels were observed. Two patients that used the gel in the abdominal skin achieved lower estradiol levels (below 60 pg/ml). We conclude that the gel increased serum estradiol levels over 60 pg/ml in four of six women, that there is a big individual variability and the application zone could influence the serum estradiol levels achieved
