  • Method of producing porous tablets with improved dissolution properties
    Publication number: 20020136767
    Abstract: A method of producing a fast-dissolving pharmaceutical delivery device of moderate strength. The delivery device is a fully formed tablet composed of readily available sugars, strength polymers and a volatilizable excipient along with an active ingredient and optional flavorings. The tablet as made will disintegrate in an aqueous medium such as saliva in under 15 seconds, making mastication unnecessary or at least requiring only one or two bites on the tablet. Essential to the invention is the easily obtainable particle size ranges of the sugars and the volatilizable excipient which promotes optimum release and tablet strength. The invention also allows for effective taste masking of the active ingredient with standard particle coating techniques.

  • Formulations and use of controlled-release indole alkaloids
    Patent number: 6416793
    Abstract: The present invention relates to spray dried hydrophobic phytochemical (i.e., yohimbine and ibogaine) compositions, a process for making such compositions and a method of using such compositions for, e.g., the promotion of weight loss. Typically, the hydrophobic dietary compositions of the present invention exhibit enhanced absorptivity when taken orally.

  • Bleaching agent
    Patent number: 5336433
    Abstract: The present invention relates to particles having a core comprising a peroxy compound and a hydrophobic coating comprising:(a) a hydrophobic substance selected from saturated fats, waxes or phosphatides;(b) a surfactant dissolved in the hydrophobic substance;(c) water swellable grains;the hydrophobic substance and the surfactant being substantially inert in respect of the peroxy compound.The invention also relates to preparation and use of the particles. Further, the invention relates to a composition containing such coated particles.
