A double-blind, randomized study was carried out in 43 women, who had undergone spontaneous menopause at least 6 months earlier, to compare the effectiveness and tolerance of veralipride with that of a conjugated oestrogens preparation in the control of hot flushes. Twenty-one women received 100 mg veralipride per day and 22 were due to receive 1.25 mg per day of the hormone preparation over a period of 20 days but 3 women in the oestrogen group discontinued the trial without giving any reason. The number, duration and severity of hot flushes were assessed and scored at the start of the trial and during treatment. Statistical analysis of the results showed marked relief with both preparations but no significant difference between them in terms of effectiveness or tolerance. Veralipride, however, appeared to provide better control in patients who had complained of severe hot flushes initially.
