Brief Summary:
The interruption of the secretion of sex steroids occurring during menopause, causes a change in vascular pattern at various levels. As a result, several agencies have side effects that interfere with women's health. The use of hormone replacement therapy has contributed to the improvement in these effects. In previous studies the investigators showed the effect of sex steroids in premenopausal women in the conjugated equine estrogens, medroxyprogesterone acetate and tibolone in menopausal women, on the central retinal arteries. The aim of this study is to evaluate the effects of Tibolone in Flow-Mediated Dilatation of the brachial artery.

MedlinePlus related topics: Menopause

Arm Intervention/treatment
Experimental: Tibolone use
climacteric women will use Tibolone for 30 days
Drug: Tibolone
Experimental group will use 2.5mg of tibolone for 30 days
Other Name: Livial

Placebo Comparator: Placebo use
climacteric women will use placebo for 30 days
Drug: Placebo
patients of the placebo group will use placebo one a day for 30 days

Primary Outcome Measures :
  1. Diameter measurement of the brachial artery using flow-mediated dilation of post menopausal women, before and after use of tibolone. [ Time Frame: 30 days ]
    We will evaluate the vascular effect of Tibolone on the brachial artery. The diameter of the artery will be measured before and one month after use of Tibolone and, in both situations, before and after the use of a cuff in the forearm. Measurement will be in millimeters.

Secondary Outcome Measures :
  1. Patients symptoms before and after the use of Tibolone [ Time Frame: 30 days ]
