  • Patent number: 5876759
    Abstract: The present invention relates to a compressed pharmaceutical dosage form containing pharmaceutical particles coated with a taste-masking composition, a water-disintegratable, compressible carbohydrate and a binder. These components are dry blended and compressed into a dosage form, such as a tablet, having a hardness sufficient to cause the carbohydrate to disintegrate within 30 seconds after oral administration, thereby allowing the coated particles to be swallowed.

  • Patent number: 5405617
    Abstract: A physicochemically stable pharmaceutical matrix composition is provided comprising: a pharmaceutical active and a water insoluble aliphatic or fatty acid ester, preferably stearyl stearate; a taste mask carrier for pharmaceutical actives comprising a taste masking effective amount of an aliphatic or fatty acid ester; and a method for preparing a pharmaceutical matrix without the use of organic and/or volatile solvents comprising the steps of: melting an aliphatic or fatty acid ester; admixing at least one pharmaceutical active with the molten aliphatic or fatty acid ester; and solidifying the admixture to produce a pharmaceutical matrix composition. The matrix is composed of an aliphatic, or fatty acid, ester that has a low melting point (50.degree.-100.degree. C.) and the melt exhibits: low viscosity, recongeals rapidly when cooled, does not exhibit polymorphism, and has good mold release properties.
