Abstract
The transdermal system includes a sex hormone-containing adhesive matrix, which contains inclusions of a sex hormone in a hydrophilic non-crosslinked polymer in dissolved or dispersed form. The inclusions have a concentration of 20 to 90 percent by weight of the sex hormone, which is more than 50 percent by weight amorphous. The hydrophilic non-crosslinked polymer can be polyvinylpyrrolidone, methylcellulose, ethylcellulose or hydroxyethylcellulose. The adhesive matrix can be a polyisobutylene, ethylene-vinyl-acetate copolymer or a polystyrene-butadiene block copolymer.
