    • The present invention relates to the field of therapeutical chemistry and more particularly to pharmacotechny. Specially, the present invention relates to new compositions adapted to local administration and more precisely to forms intended to be placed in the subcutaneous tissues and commonly called implants. Said implants are of various natures (hydrophobic, hydrophilic, biodegradable) and of various types (reservoir, matrix). Said implants incorporate an efficient dose of a derivative of 3,20-dioxo 6-methyl 17(alpha)-acetoxy 19-nor pregna 4,6-diene optionally substituted in the 3 and/or 17(alpha) position, associated or mixed with a biologically acceptable inert excipient. The implants thus obtained are efficient contraceptive agents having an active duration of a least one year with minimum secondary effects.
    • 本发明涉及治疗化学领域,更具体地涉及药理学技术领域。 特别地,本发明涉及适于局部施用的新组合物,更准确地说涉及旨在放置在皮下组织和通常称为植入物中的形式。 所述植入物具有各种性质(疏水性,亲水性,生物降解性)和各种类型(储层,基质)。 所述植入物掺入有效剂量的3,20-二氧代6-甲基17(α) - 乙酰氧基19-去甲前na 4,6-二烯衍生物,其在3和/或17(α)位置任选取代,相关联或混合 具有生物学上可接受的惰性赋形剂。 如此获得的植入物是具有至少一年的活性持续时间并且具有最小次要效果的有效的避孕药。
