PHARMACEUTICAL COMBINATION PREPARATION FOR HORMONAL CONTRACEPTION

摘要

A combined pharmaceutical preparation has two sequential administration hormonal components that are separately packed in a packaging unit. Each hormonal component consists of a plurality of separately packed daily dosage units that may be individually withdrawn from the package. A first hormonal component contains as hormonal active substance a combination of an oestrogen preparation and of a gestagen preparation in a dose that is at least sufficient to inhibit ovulation. The second hormonal component contains as hormonal active substance only an oestrogen preparation. The first hormonal component comprises 23 or 24 daily units and the second hormonal component comprises 4, 3, or 2 daily units. Between both hormonal components are placed 2 or 1 active substance-free daily units (placebos) or are indicated 2 or 1 pill-free days. The total number of hormonal daily units and active substancefree daily units or pill-free days equals the total number of days in the desired cycle that has however at least 28 days. This combined preparation for feminine contraception has an as low as possible oestrogen content in each individual dosing unit and also a low total hormone content per administration cycle, while having a high contraceptive safety, a low incidence of follicle development, and allowing an irreproachable cycle control and reliably avoiding spotting and undesirable side effects.
