Abstract

The administration of sex hormones, particularly testosteorne, progesterone and estradiol in the form of their complexes or inclusions with specific derivatives of cyclodextrins by the sublingual or buccal route results in effective transfer of these hormones into the systemic circulation, followed by only gradual elimination. To be effective in the above mode of administration, the derivatives of cyclodextrins must carry one or several substituents, each containing one or several hydroxy groups. Specially preferred are the following complexes: hydroxypropylbeta-cyclodextrin and poly-beta-cyclodextrin.
