Summary

The study aims to asses the effects of micronized (MIC) and nanoparticulate (NANO) transdermal hormone therapy (THT) on blood pressure, ultra-sensitive C-reactive protein (CRP), and cardiovascular risk factors in postmenopausal women.

Clinical Details

Official title: Nanoparticulate Versus Micronized Steroids Delivery for Transdermal Hormone Replacement Therapy: Effects on Blood Pressure, Insulin and C-reactive Protein and in Postmenopausal Women

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome: Blood Pressure variation

Secondary outcome: C-reactive protein levels after treatment

Detailed description: In this open label study, 27 postmenopausal women, with no clinical evidence of cardiovascular disease, were randomly divided in two groups. During 12 weeks, 15 patients received on the left forearm micronized (MIC) THT (micronized 17β-estradiol 2. 5 mg/day + progesterone 100 mg/day). and 14 patients received a nanoparticulate (NANO) THT (nanoparticulate 17β-estradiol 2. 5 mg/day + progesterone 100mg/day). After 12 weeks of treatment patients were evaluated. Baseline and Post-THT measures were determined: Insulin, body mass index, waist circumference, blood pressure, CRP-stratified levels, total testosterone, TSH and FSH levels.
