Abstract
The present invention provides compositions and methods for the transdermal administration of a contraceptively effective amount of gestodene and estrogen, such as ethinyl estradiol, in combination, together with a suitable permeation enhancer. The amount of the estrogen codelivered is kept at an about constant and contraceptively effective rate while the amount of gestogen codelivered varies depending on the phase of the menstrual cycle but remains at a contraceptively effective rate. The size of the system may also vary depending on the amount of gestogeno be delivered.
