The invention relates to a pharmaceutical composition in the form of a system in film form for transmucosal administration of steroid hormones. An administration system for steroid hormones which dissolves in the mouth and which releases with a high bioavailability is disclosed. The administration system in film form dissolves in the mouth preferably in a period of less than 30 min, and the steroid hormone entering the bloodstream transmucosally from the administration system leads to a rapid rise in the concentration in the blood. It is thus possible to achieve a maximum concentration of this steroid hormone in the blood in a period of less than 60 min after administration.本發明係關於一種透黏膜投予類固醇激素所用之呈膜形式系統的藥學組成物。本發明揭示一種可讓類固醇激素溶解在口中且以高生物利用率釋放之類固醇激素投藥系統。該呈膜形式的投藥系統較佳地在少於30分鐘期間內溶解在口中，且從該投藥系統透黏膜地進入血液流中之類固醇激素可導致血液中濃度快速上升。如此可在投予後短於60分鐘之期間內達到此激素在血液中的最大濃度。
