  • Publication number: 20010046472
    Abstract: Methylphenidate or other drugs are provided in a formulation for oral administration that releases the drug in two or more pharmacokinetic spikes, by combining different release forms in a single formulation. In a preferred embodiment for methylphenidate, the first pharmacokinetic spike is achieved by the release of taste-masked methylphenidate which is not enterically coated, while a second pharmacokinetic spike is achieved by the release of methylphenidate in a finely divided form from enterically coated pellets or microparticles formulated for rapid release following dissolution of the enteric coating. A critical aspect of the formulation is the inclusion of excipients that create a burst release following the initial rapid release and uptake. The formulation can be administered as a paste, jelly, suspension, or fast dissolving wafer. To manipulate the dose, the formulation can be provided, for example, as a paste packaged in a tube similar to those used to dispense toothpaste.

  • Patent number: 6261601
    Abstract: A pharmaceutical composition in the form of tablets or capsules provides a combination of temporal and spatial control of drug delivery to a patient for effective therapeutic results. The pharmaceutical composition comprises a drug, a gas generating component, a swelling agent, a viscolyzing agent, and optionally a gel forming polymer. The swelling agent belongs to a class of compounds known as superdisintegrants (e.g., cross-linked polyvinylpyrrolidone or sodium carboxymethylcellulose). The viscolyzing agent initially and the gel forming polymer thereafter form a hydrated gel matrix which entraps the gas, causing the tablet or capsule to be retained in the stomach or upper part of the small intestine (spatial control). At the same time, the hydrated gel matrix creates a tortuous diffusion path for the drug, resulting in sustained release of the drug (temporal control). A preferred once daily ciprofloxacin formulation comprises 69.9% ciprofloxacin base, 0.34% sodium alginate, 1.03% xanthan gum, 13.

    Abstract: The present invention is an additive preparation for use in bodily fluid collection devices. The additive preparation has an additive, an organic acid and a metal carbonate compound. The preparation effervesces when in contact with a body fluid sample, thereby efficiently dispersing in a body fluid sample. The formulation is desirably tabulated to provide an effective, easily stored, and handled preparation. However, a binding or bulking agent may be added to the additive preparation formulation to provide binding and lubricating properties to the formulation. A binding agent enables granulating of the formulation without the forming of a pellet.

    Abstract: The present invention relates to a system that is self-foaming. The self-foaming system has at least two components that are maintained in separate containers. The components produce carbon dioxide when they commingle with each other upon being dispensed from their individual containers. The components are stored separately by being partitioned in separate containers or a container having a chamber for each of the components. The self-foaming system of the present invention has cleansing and cooling properties. The system is mild yet non-irritating because it cools and cleans deeply without interfering with the natural barriers of the skin.

  • Patent number: 5776470
    Abstract: Active ingredient system for the lipid exchange with target structures; methods for their manufacture and their use; and products containing active ingredient systems of this type are disclosed. The active ingredient system for the transfer of lipophilic and/or amphophilic components to target structures or from such back to the active ingredient system, as well as to their exchange with the target structures, is formed from at least one lipid component with at least one transfer protein. In the method for the manufacture of the active ingredient system, lipid and protein components are combined into system in different configurations depending on the purpose of its use and its place of use, whereby the specificity results from the lipid used and the transfer protein employed, as well as the direction of the lipid transfer. Active ingredient system of this type are used in technology, such as the material technology, in medicine, pharmaceuticals and in the area of cosmetology.

  • Patent number: 5776431
    Abstract: Compositions in which aspirin is present in combination with alkaline compounds, especially those containing water of crystallization (hydrates), deteriorate on standing. This deterioration may take several forms: It can be a physical deterioration in which such aspirin compositions become completely unmanageable, wet, gummy, sticky masses; or chemical decomposition in which aspirin loses its molecular structure chiefly by losing the acetyl group. The latter is accompanied by formation of acetic acid, the mixture developing its characteristic acetic odor. In both cases, such compositions become entirely unsuitable for all practical commercial and medicinal purposes. Yet, when preparation of water-soluble aspirin compositions is desired, it is impossible to avoid the use of alkaline compounds. This is because the only known method of converting aspirin into soluble form is by means of reacting it with an alkaline compound to form the soluble salt of aspirin.
