Date Apr. 13, 1995Transdermal therapeutic systems containing as active ingredients oestradiol and norethisterone acetate have added thereto octyldodecanol to reduce or avert crystal formation after storage. The use of octyldodecanol thus makes it possible to produce a storage-stable system with the active ingredients oestradiol and norethisterone acetate with a high thermodynamic activity.
