HRT and long-term compliance: the efficacy and safety of Menorest

Hormone replacement therapy (HRT) is perhaps the most important development in preventive medicine in the Western world for half a century, yet long-term compliance is notoriously poor. Up to 75% of women who start on HRT are reported to drop out within the first 6 months. Poor compliance may arise from a lack of awareness of the benefits of HRT, or from a number of common misconceptions, particularly the idea that HRT is ¿unnatural', and will cause weight gain, cancer, or unpleasant side effects. While side effects (usually progestogenic) may of course occur on HRT, they can usually be managed by a change in the regimen. Studies of the efficacy and safety of Menorest, an adhesive matrix transdermal system, used in combination with dydrogesterone for 12 days in each cycle, show it to be effective in relieving menopausal symptoms and increasing lumbar and spinal bone mass. Menorest was as effective and well-tolerated as a reference oral treatment (conjugated estrogens), and its twice weekly application may be considered to promote compliance.
