  • Publication number: 20070054830
    Abstract: A cleanser composition suitable for use with oral appliances, which provides a sensory signal to the user. The sensory signal is such that the user believes the signal to indicate that cleasing of the oral device if occurring or, alternatively, that cleansing action has ceased.

  • Publication number: 20050266079
    Abstract: The present invention is directed to application of novel process conditions for aqueous coating techniques of water soluble active agents, and its application to production of sustained release beadlets of said agents. The improvement lies in the determination and use of the glass transition point for the water swellable polymer used to produce the sustained release effect, and control of the moisture content of the air by dew point.

  • Publication number: 20050202084
    Abstract: A pharmaceutical composition in the form of a chewable tablet for the suppression of gastric reflux comprising an alginic acid or salt thereof, a water-soluble carbonate radical precursor, a calcium salt, a first bulk sweetener, and a binding agent. The calcium salt and either or both of the bulk sweetener and the binding agent may be blended via any of wet granulation, spray drying, or compression processes prior to admixture with the alginic acid and the carbonate radical precursor.

  • Patent number: 6136864
    Abstract: A pharmaceutical composition has an acid salt of a sympathomimetic amine; and a denaturant of (i) at least one gum or viscosity modifier, and (ii) at least one surfactant, wherein the gum or viscosity modifier and the surfactant are present in amounts sufficient to have a denaturing effect on the sympathomimetic amine without significantly compromising the release of the sympathomimetic amine from the composition.

  • Patent number: 6027746
    Abstract: The present invention relates to novel liquid oral suspensions incorporated within a soft gelatin capsule comprised of a bitter or bad-tasting pharmaceutical active (such as antihistamines, decongestants and the like) which is dispersed within an adsorbate comprised of magnesium trisilicate, silicon dioxide or mixture thereof. The adsorbate is dispersed within an aqueous or non-aqueous carrier base and combined with other flavors, sweeteners, emulsifiers and the like. The adsorbate not only taste-masks the active but also insures that is evenly dispersed through the liquid suspension so that a uniform dosage rate is readily achievable. The encapsulation of the adsorbate within a gelatin capsule makes administration easier for children andmore convenient. The capsule also affords the adsorbate suspension greater shelf life.

  • Patent number: 5681577
    Abstract: A chewable cold/sinus preparation comprising a bitter tasting mixture of a decongestant such as pseudoephedrine and an antihistamine such as diphenhydramine and/or chlorpheniramine maleate is made with no bitter, metallic taste or unpleasant mouthfeel by adsorbing the active drug mixture using a wet granulation process onto a silicon dioxide carrier which comprises from about 50 to about 85% of total weight of the adsorbate composition. A truly multi-symptom relief formula is prepared through the optional addition of an antitussive such as dextromethorphan hydrobromide and/or an analgesic such as meclofenamic acid, aspirin or ibuprofen. Additional excipients such as flavors, sweeteners, lubricants and bulk fillers are added for better taste, improved mouthfeel and as an aid to the tabletting process.

  • Patent number: 5641536
    Abstract: A method for coating pharmaceutical tablets is disclosed in which polymeric coating ingredients are combined with saccharides in a melt spinning operation to form composite particulates. The particulates are then dispersed in water to form an aqueous polymer coating solution, followed by application to pharmaceutical tablets by such methods as spray coating. The particulates dissolve extremely rapidly in water to form a dispersion of the polymer coating ingredients. Such rapid dissolution allows for increased processing rates and avoids disadvantages of the prior art such as the requirement of high shear rate mixing for long times.

  • Patent number: 5626878
    Abstract: A medicament adsorbate containing corn syrup having contained therein from about 10 to about 90% by weight of the adsorbate of a medicament drug a magnesium trisilicate having a surface area of at least 400 m.sup.2 /g and having a structure with multiple interstitial spaces, and having adsorbed therein from about 0.5 to about 30% by weight of the adsorbate of a medicament drug, wherein the medicament drug is an antihistamine. A reduction in the electrostatic forces between adsorbates is experienced due to the particle size of the adsorbate being in the range greater than 40 to about 800 um, most of the adsorbates prepared being a particle size greater than 150 um, which allows for better processing.
