Primary Objective:
To examine the effectiveness of non-hormonal pharmacological treatments for relieving hot flushes in postmenopausal women.
In separate comparisons, we will assess non-hormonal treatments for their effectiveness in the relief of hot flushes:

• Non-hormonal treatments versus placebo
• Non-hormonal treatments versus hormonal replacement therapy
• Non-hormonal treatments versus no-treatment control group

Secondary Objectives:
To determine the adverse effects of non-hormonal treatments.
To evaluate the impact on quality of life of non-hormonal treatments versus no-treatment control, placebo or hormonal replacement therapy.
