    • The present invention relates to a method of making a film composition with an improved uniformity of active composition. The invention includes a method including the steps of forming a flowable film composition comprising an edible water-soluble polymer, a polar solvent and a particulate active suspended therein, where the ratio of solids to liquids is at least about 95 to about 5 and where the composition comprises a mixture having compositional uniformity per unit volume; directing the flowable film composition to a transfer trough, the transfer trough including a first rotating roller and a movable transfer substrate upon which to form the film; and maintaining uniformity of the flowable film composition during the residence time in the trough by maintaining the rate of composition entering the transfer trough and the level of the flowable film composition in the transfer trough at a substantially constant level. Methods of administering the active are also contemplated.
    • 本发明涉及制备具有改善的活性组合物均匀性的薄膜组合物的方法。 本发明包括一种方法,其包括形成包含可食用水溶性聚合物,极性溶剂和悬浮于其中的颗粒活性物质的可流动膜组合物的步骤,其中固体与液体的比例至少为约95至约5, 组合物包含具有每单位体积的组成均匀性的混合物; 将可流动膜组合物引导到转移槽,转移槽包括第一旋转辊和可移动转移基底,在其上形成膜; 并且通过保持进入转移槽的组合物的速率和转移槽中的可流动的膜组合物的水平基本上恒定的水平,保持在槽中的停留时间期间可流动的膜组合物的均匀性。 也考虑施用活性物质的方法。
