ABSTRACT:
A method of contraception in mammalian females, which method comprises the parenteral or rectal administration of an estrogenic component and a progestogenic component to a female of childbearing capability in an amount effective to inhibit ovulation, wherein the estrogenic component is selected from the group consisting of substances represented by the following formula (1)in which R1, R2, R3, R4independently are a hydrogen atom, a hydroxyl group or an alkoxy group with 1-5 carbon atoms; each of R5, R6, R7is a hydroxyl group; and no more than 3 of R1, R2, R3, R4are hydrogen atoms; precursors capable of liberating a substance according to the aforementioned formula when used in the present method; and mixtures of one or more of the aforementioned substances and/or precursors. Another aspect of the invention concerns a drug delivery system for parenteral or rectal administration that contains the aforementioned estrogenic component and a progestogenic component, said drug delivery system being selected from the group consisting of suppositories, systems for intravaginal delivery, inhalers, nasal sprays and transdermal delivery systems.
