    • The invention relates to a method for producing an oral solid dosage form capable of instantaneous release of the active substance which is a sparingly water-soluble antiestrogen, particularly tamoxifen citrate, characterized in that the antiestrogen is pre-mixed with a water-insoluble and/or alcohol-insoluble filler and optionally with at least one further pharmaceutically acceptable excipient, 80 % of particles of the filler or its mixture with at least one further pharmaceutically acceptable excipient being smaller than 355 micrometers and at most 10 % of these particles being smaller than 40 micrometers, whereupon the triturate obtained is mixed with a water-insoluble and/or alcohol-insoluble filler and with a water-soluble and/or alcohol-soluble binder and optionally with at least one further pharmaceutical excipient, 80 % of particles of the mixture of the filler and binder and optionally of at least one further pharmaceutically acceptable excipient being smaller than 355 micrometers and at most 10 % of these particles being smaller than 40 micrometers, and the mixture obtained is granulated in the presence of water and/or alcohol which are used in an amount smaller than or equal to 8 % by weight, based on the total weight of the wet granulated mixture, whereupon the granulate obtained is dried. The invention also relates to the thus-obtained oral solid dosage form.
    • 本发明涉及一种能够即时释放活性物质的口服固体剂型的方法,该活性物质是微水溶性抗雌激素,特别是柠檬酸他莫昔芬,其特征在于将抗雌激素预先与水不溶性和/ 或醇不溶性填料和任选与至少一种其它药学上可接受的赋形剂,80%的填料或其混合物与至少一种其它药学上可接受的赋形剂的颗粒小于355微米,并且至少10%的这些颗粒小于 所得到的研磨剂与水不溶性和/或醇不溶性填料和水溶性和/或醇可溶性粘合剂和任选与至少一种其它药物赋形剂混合,80% 填料和粘合剂的混合物和任选的至少一种另外的药学上可接受的赋形剂小于355微米 这些颗粒中至少10%小于40微米,所得混合物在水和/或醇的存在下造粒,其用量小于或等于8重量%,基于总和 湿颗粒状混合物的重量,然后将获得的颗粒干燥。 本发明还涉及由此获得的口服固体剂型。
