  • Patent number: 9717682
    Abstract: Improved pharmaceutical solid oral film dosage forms for the buccal and/or sublingual delivery of pharmaceutical, nutraceutical or cosmetic ingredients are endowed with instant hydration potential and complete dissolution potentially enabling the active ingredient to become immediately available for enhanced buccal and/or sublingual absorption and/or reduced absorption through the gastrointestinal route. The improved delivery systems for solubilizing and stabilizing pharmaceutically active ingredients exhibit enhanced stability by the use of a combination of crystallization inhibitors, which together can maintain the active ingredient in a desired plurality of particles in an effective size range within a polymeric film matrix.

  • Publication number: 20090214640
    Abstract: The present invention relates to a delayed release pharmaceutical oral dosage form and method of making same. The delayed release dosage form comprises one or more active ingredients within a granulated composition, which further comprises one or more excipients selected from the group of solid aliphatic alcohols, fatty acid esters, mixtures of esters of saturated fatty alcohols and saturated fatty acids, natural waxes, synthetic waxes, hydrogenated castor oil, hydrogenated vegetable oil, gums, and mixtures thereof; and one or more polymers or copolymers exhibiting a pH-dependent solubility. The present invention also related to method of making these delayed release dosage form.

  • Publication number: 20070190144
    Abstract: A multilayer oral dosage form that provides controlled release of an active compound includes a non-erodible core containing a pharmaceutically active compound and/or a nutritionally active compound, and at least one release-modulating layer laminated to each side of the core layer. The dosage form can be prepared using simple, inexpensive tablet compression techniques.

  • Publication number: 20070190139
    Abstract: The present invention relates to a multi layer pharmaceutical oral dosage form having delayed release and immediate release properties and method of making same. The delayed release formulation substantially behaves as an enterically coated dosage form but without the formulation and the application of an enteric coating. The delayed release formulation is characterized by a mixture of one or more active ingredients and one or more excipients selected from the group of solid aliphatic alcohols, mixtures of esters of saturated fatty alcohols and saturated fatty acids, natural or synthetic waxes, hydrogenated castor oil, hydrogenated vegetable oil, gums, and mixtures thereof; pH dependent soluble polymers; and optionally an opacifying agent.

  • Publication number: 20070128272
    Abstract: A nutritional solid oral dosage form for administering a calcium nutrient with an iron nutrient includes enterically coated particles, granules or pellets containing a calcium nutrient. An iron nutrient is incorporated into an immediate release matrix. The coated calcium nutrient may be located in a core surrounded by the immediate release matrix or distributed in the immediate release matrix. The coating and matrix are formulated to allow immediate release of the iron nutrient in an upper part of the gastrointestinal tract and delayed release of the calcium nutrient until the remainder of the dosage forms reaches a higher pH region of the gastrointestinal tract.

  • Publication number: 20060127478
    Abstract: A multi-layer oral dosage form, preferably a tablet, comprising a matrix core comprising a therapeutically effective amount of a first drug (NSAID), wherein the matrix core allows sustained release of the first drug; a first layer, which is in contact with the matrix core, comprising a first portion of a pharmaceutically effective amount of a second drug (H2-blocker antagonist), wherein the first layer allows sustained release of the second drug; and a second layer, which is in contact with said matrix core, comprising a second portion of the second drug, wherein the second layer allows immediate release of the second drug. Methods for preparing the multi-layer dosage form are also disclosed.
