    Abstract: Disclosed is a substantially anhydrous, powdered, galactomannan composition consisting essentially of a galactomannan hydrocolloid exhibiting about 50% to about 90% by weight of anhydromannose residues and about 10% to about 50% by weight anhydrogalactose residues; less than about 1% by weight of protein material and less than about 3% of other nonaqueous impurities. This material is useful for preparing pharmaceutical compositions both in the substantially anhydrous form but preferably in an anhydrated form which includes about 5-15% by weight water. The pharmaceutical compositions comprise a therapeutically effective amount of a drug, the hydrated powered gallactomannan composition and optionally other pharmaceutically-acceptable excipients. When the hydrated powdered purified glactomannan of the invention is used to form a tablet, one sees improved hardness in the tablet formed.

  • Patent number: 6060078
    Abstract: The present invention relates to a chewable tablet containing a medicament in a core and a process for preparation thereof. In particular, the present invention relates to a chewable tablet comprising a core containing a medicament in the center of the tablet in a state of jelly or chewable base and an outer layer wrapping the core which is made up of chewable base such as a gum, a soft candy or a caramel. The chewable tablet is easy to take and has a good taste and nice chewing property due to the unique tablet form. In addition, the tablet has an advantage in bioavailability resulting from increased absorption rate and excellent stability due to unique preparation process. Therefore, the chewable tablet and the preparation process of the present invention can be used in pharmaceutical industry usefully.

  • Patent number: 6022565
    Abstract: A poison ivy (and related dermatitis) treatment composition and method in which a novel composition containing a combination of active ingredients gives new and unexpected results over compositions of the prior art. The inventive composition includes three essential ingredients: extract (fresh sap) of jewelweed (Impatiens species); fresh sap of plantain leaf; and an aqueous colloidal dispersion of subdivided whole oat grains. It is believed that the amphiphilic nature of the aqueous colloidal oat dispersion both preserves the activity of the plantain and jewelweed enzymes, as a result of its oat oil fraction, and also enhances topical delivery to the epidermis due to its aqueous fraction and the stabilizing effect of the oat bran as bulking agent.
