This trial is conducted in Europe. Postmenopausal women with moderate to severe hot flashes have been recruited into the trial. The earliest effect of ultra low dose HRT (hormone replacement therapy) on frequency and severity of menopausal symptoms, bleeding patterns and safety of different hormonal combinations will be evaluated and compared to placebo over the six month treatment period.

Condition Intervention Phase
Menopausal Vasomotor Symptoms
Drug: 0.5 mg estradiol / 0.1 mg norethisterone acetate (NETA)
Drug: 0.5 mg estradiol / 0.25 mg norethisterone acetate (NETA)

Primary Purpose: Treatment
Official Title: A Six Month Double-blind, Randomised, Parallel-group, Placebo-controlled, Multi-centre Trial to Investigate the Efficacy and Safety of Two Ultra-low Dose Combinations With 0.5 mg Estradiol and 0.1 mg or 0.25 mg Norethisterone Acetate (Activelle Low Dose 0.1/Activelle Low Dose 0.25) for Treatment of Menopausal Symptoms
