    Abstract: Medi-Cap a specialized absorbable capsule of various shapes and sizes. It may come prefilled with desired medication or material or it can come in a two-piece snap together capsule that can be filled with desired medication/material by the medical professional. (Most Likely prefilled) Medi-Cap will be time released meaning that each capsule used in an area of treatment will have a specific time in which the capsule will degrade and release the medication in the area of operation or treatment. Depending on what Medi-Cap will be used for there should be different capsules with different absorbing times.

  • Patent number: 8101203
    Abstract: A method for making a clear hard vegetarian gelatin free two piece capsule by creating a first phase network system using a seaweed extract, a galactomannan extract and a rheology modifier. A filler is created for the first phase network by blending a water, a crystalline alcohol, a polysaccharide, and a sugar alcohol at a temperature less than 80 Fahrenheit. The filler is then mixed into the first phase network system forming a biphasic system. Capsules are then formed by dipping conventional moulding pins into the biphasic solution, blowing hot air on the dipped pins in a chamber with a humidity that is no more than 25 percent, blowing away water on the outer surface of the dipped pins to bond and lock moisture to the polysaccharide and removing the capsule pieces from the pins.

    Abstract: The present invention provides a dosage form that prevents misuse of the medicament contained within. The dosage form contains an inactivating substance in combination with the medicament, wherein the two substances are separated by a permeable or semi-permeable partition. The partition becomes impermeable upon activation by a medical professional, thereby effectively sequestering the inactivating substance from the medicament and allowing for the intended administration of the medicament to the patient. Unless activated, however, the inactivating substance and medicament remain commingled in the dosage form, and any attempt to dispense the medicament before activation will result in the release of inactivated medicament.

    Abstract: A liposome-capsule dosage unit system for the delivery of a biologically active material is formed by encapsulating a biologically active materials in liposomes and then placing the liposome encapsulated material into a capsule. The capsule is typically a soft gel capsule or a two piece capsule capable of tolerating a certain amount of water. A less water tolerant capsule can be employed if the liposomes are dehydrated prior to placement within the capsule. Biologically active material include drugs, nutritional supplements, vitamins, minerals, enzymes, hormones, proteins and polypeptides. The system is especially suited for the delivery of materials with poor oral solubility, materials that are not absorbed or are poorly absorbed from the gastrointestinal tract, and materials that have conventionally been given by an invasive route. The system can be administered orally, intra-occularly, intranasally, rectally, or vaginally.

  • Patent number: 6656501
    Abstract: The present invention is directed to improved oral dosage forms that are significantly easier to swallow. In accordance with the present invention, the oral dosage forms are configured to have relatively greater weight and/or density to effect partial or total submergence in the liquid with which the oral dosage form is taken. In one embodiment, a filler is added to the ingredients of the oral dosage form. In another embodiment, a filler is added to the medium of the oral dosage form. In a further embodiment, a filler is added to the exterior of the oral dosage form. In another embodiment, a relatively heavier, denser or larger amount of ingredient is used to formulate the oral dosage form. In yet a further embodiment, a binder is used to increase the weight and/or density of the oral dosage form. In yet another embodiment, a combination comprising a binder and a relatively heavier, denser or larger amount of ingredient is used to formulate the oral dosage form.

  • Patent number: 6613353
    Abstract: Capsule formulations are provided containing at least two different fill compositions which are prevented from mixing either by providing both of the fill compositions as solids or by providing a physical barrier which separates the fill compositions so that they are prevented from mixing. The invention has the advantage that two different formulations can be provided in a single capsule without one of the formulations having an adverse effect on the other.

  • Patent number: 6576255
    Abstract: The invention relates to a process for making molded articles by means of injection molding with the process steps of a) melting of a (meth)acrylate copolymer, which is composed of 30 to 80 wt % of radical-polymerized C1 to C4 alkyl esters of acrylic or methacrylic acid and 70 to 20 wt % of (meth)acrylate monomers with a tertiary ammonium group in the alkyl residue, wherein the (meth)acrylate copolymer is present in a mixture with 1 to 70 wt % of a plasticizer and a desiccant in the ratio of 1:1 to 1:20 and also with 0.05 to 5 wt % of a release agent, and further standard additives or adjuvants and if necessary even a pharmaceutical active principle can also be present in the mixture, and before the mixture is melted it has a content of more than 0.5 wt % of low-boiling constituents with a vapor pressure of at least 1.9 bar at 120° C., b) degassing of the mixture in the thermoplastic condition at temperatures of at least 120° C.

  • Patent number: 6419952
    Abstract: A dosage form comprising a gelatin capsule formed with a composite wall and containing a liquid, active agent formulation where the wall comprises a barrier layer formed over the external surface of the gelatin capsule, an expandable layer formed over the barrier layer and a semipermeable layer formed over the expandable layer is described. The dosage forms and methods provide for the conversion of standard gelatin, liquid formulation capsules into controlled, release dosage forms that permit the controlled release of the active agent into the environment of use over time.

  • Patent number: 6350468
    Abstract: A pharmaceutical dosage form particularly suitable for the administration of active principles in multiple therapies is disclosed. The pharmaceutical dosage form is a double capsule where in an internal capsule is placed inside an external one. Each internal and external capsule includes one or more active principles. A double capsule according to the invention is preferably used in triple or quadruple therapies against the microorganisms Helicobacter Pylori. Advantages of this pharmaceutical dosage form consist in providing a simple posology for administration of two and more active principles, allowing the active principles to activate at the right intervals of time and in the preestablished quantities, and preventing interactions between active principles.

  • Patent number: 6326026
    Abstract: A simulated capsule-like medicament comprising a subcoating of a mixture of a water-soluble, film-forming polymer, e.g. hydroxypropylmethyl cellulose and a hydrophobic plasticizer, e.g. castor oil, which promotes a smooth uniform and substantially bubble free outer coating, e.g. gelatin, for the capsule-like medicament; capsule-like medicaments which are slightly bowed in shape; and a process of making such medicaments.

  • Patent number: 6303144
    Abstract: A controlled release preparation containing at least one kind of a pharmaceutically active ingredient, a male piece and a female piece, the pieces fitting together to enclose the active substance therein, wherein the male piece is made from a material that gels in the intestinal juice, is disclosed. In a preferable mode, the male piece contains an ethyl acrylate-methyl methacrylate-trimethylammonioethyl methacrylate chloride copolymer and a methacrylic acid-ethyl acrylate copolymer. In a preferable mode, the female piece is made from a water insoluble polymer. In a preferable mode, the dosage form is a tablet or a capsule.

  • Patent number: 6245350
    Abstract: A process for encapsulation of caplets in a capsule comprises the following steps: a. providing empty capsule parts; b. filling at least one of said capsule parts with one or more caplets; c. putting said capsule parts together; and d. treating the combined parts by cold shrinking. The solid dosage forms obtainable by such a process are tamper-proof in that they cannot be opened in a way to be reassembled without showing such opening process.
