Drospirenone-containing preparations for transdermal use

The pharmaceutical preparation for transdermal administration contains solvent ingredients, such as water and ethanol and / or propanol, and drospirenone. The drospirenone is contained in the preparation in an amount that is not above its saturation solubility in an initial state prior to application to skin. However after application to the skin the amount of drospirenone exceeds its saturation solubility due to escape or discharge of the solvent ingredients from the preparation. Preferably the saturation solubility is exceeded by at least a factor of five during application to the skin. The pharmaceutical preparation can also contain an estrogen, such as ethinyl estradiol. It can be in the form of a semi-solid or liquid preparation that is contained in a reservoir-type transdermal patch.
