    • Vitamin E TPGS/drug compositions and methods are provided which obviate the need for surfactants or non-evaporated co-solvents because the active drug component is dissolved directly into Vitamin E TPGS to form a true molecular solution--not an emulsion or a micro-emulsion. The invention provides a slowly dissolving TPGS/Drug matrix that absorbs gastrointestinal fluid into the matrix at the dosage form/fluid interface, where a gel-like liquid crystal is formed. This gel front forms a liquid crystal boundary where drug dissolution is highest. At this liquid crystal/GI fluid boundary, a synchronization takes place in which the rate of formation of liquid crystals equals the dissolution rate of liquid crystals at the water interface, thereby giving controlled order release of the drug into the GI tract. The rate of dissolution is also controlled by the geometry of the dosage form. The solid Vitamin E TPGS/drug matrices of the invention can be solidified and compressed into tablets or filled into capsules, with other excipients, binders and/or fillers. The solid TPGS/drug solution of the invention also can be made into an immediate release liquid formulation upon addition of water, or into a controlled release system solid tablet by the use of impermeable or semi-permeable barriers or coatings surrounding portions of the tablet.
    • 提供维生素E TPGS /药物组合物和方法,其消除了对表面活性剂或非蒸发共溶剂的需要,因为活性药物组分直接溶解于维生素E TPGS中以形成真正的分子溶液 - 而不是乳液或微乳液 。 本发明提供了缓慢溶解的TPGS /药物基质,其在形成凝胶状液晶的剂型/流体界面处将胃肠液吸收到基质中。 该凝胶前体形成药物溶出度最高的液晶边界。 在该液晶/ GI液体边界处,发生液晶的形成速率等于水界面处的液晶的溶解速率的同步,从而将药物控制释放到GI道中。 溶解速率也可以通过剂型的几何形状来控制。 本发明的固体维生素E TPGS /药物基质可以固化并压制成片剂或者与其它赋形剂,粘合剂和/或填充剂一起填充到胶囊中。 本发明的固体TPGS /药物溶液还可以通过加入水制成立即释放的液体制剂,或通过使用围绕片剂部分的不渗透的或半渗透的屏障或涂层,进入控释系统的固体片剂。

    • A child resistant tablet package accommodates low density pharmaceutical tablets. The package includes a blister tray having a planar surface and a plurality of spaced apart open ended tablet accommodating first blister depressions formed therein. A plurality of entry facilitating second blister depressions are provided on the planar surface spaced adjacent each first blister depression. A planar lid is removably sealed over the planar surface of the blister tray and includes portions overlying disposed over the first and second blister depressions. The lid is puncturable through the plane of the lid at a location over the second blister depressions so as to facilitate removal of portions of the lid overlying the first blister depressions so as to expose the tablets for dispensing.
    • 抗小孩片剂包装适合低密度药物片剂。 该包装包括具有平坦表面的泡罩托盘和容纳形成在其中的第一泡罩凹部的多个间隔开口的片剂。 在与每个第一泡罩凹陷相邻的平面上设有多个促进第二泡泡凹陷的入口。 平面盖可移除地密封在泡罩托盘的平坦表面上,并且包括覆盖在第一和第二泡罩凹陷上的部分。 盖子可以穿过盖子的平面穿过第二泡罩凹陷处的位置,从而有助于移除覆盖在第一泡罩凹部上的盖子的部分,以便露出用于分配的片剂。
