  • Patent number: 4990358
    Abstract: A novel capsule-like medicament and method for producing such medicaments are disclosed. The method provides a procedure for coating solid cores, such as caplets, with a first gelatinous coating on one end, and then with a second gelatinous coating on the other end which is thickner than the first, to simulate the interlocking halves of a hollow capsule. The second, thicker gelationous coating can be provided with a single gelatin coating from a bath having a higher viscosity than the bath used to provide the first gelatinous coating. Alternatively, the second gelatinous coating can be provided by double dipping to provide layers of gelatinous material or gelatin.

  • Patent number: 4968509
    Abstract: An acetaminophen-sustained release tablet or tablet layer is formed by making a wet granulation, using Povidone (PVP) in water or alcohol-water as the granulating fluid which is mixed with acetaminophen, hydroxyethyl cellulose, a wicking agent e.g. microcrystalline cellulose, then drying and milling the granulation and blending with dry powdered erosion promoter, e.g. pregelatinized starch, wicking agent, lubricant e.g. magnesium stearate and glidant e.g. silicon dioxide, and compressing the resultant granulation, which upon administration results in a slow release of the acetaminophen.

  • Patent number: 4966771
    Abstract: A capsule-like medicament, method for producing such medicaments and apparatus. Such medicaments are achieved by individually dipping and drying first one end, and then the other end, of each caplet to provide a coating which is smoother and easier to swallow than an uncoated caplet. The production of these capsule-like medicaments is readily facilitated by simple and inexpensive modifications which can be made to existing empty gelatin capsule making equipment.

  • Patent number: 4921108
    Abstract: A feeder device is provided for inserting solid medicaments, such as caplets, into a holding fixture for subsequent processing, for example, dipping in a gelatinous material. The feeder device incorporates a novel selector for eliminating partial pieces of medicaments before these pieces can be disposed into the holding fixture. The disclosed simple mechanical selection apparatus can eliminate these pieces efficiently prior to costly additional processing steps. Also included with this invention are novel mechanisms for regulating the flow of medicaments from a hopper to a plunger assembly, whereby a single medicament at a time can be inserted into a corresponding holding fixture.

  • Patent number: 4816305
    Abstract: A tamper-resistant vessel which contains a liquid is provided with a non-adherent multi-walled construction having, in one embodiment, at least two adjacent non-adherent layers for providing a void in between to enable tamper indication by discoloration indicative of gross spoilage. In one embodiment, the container or vessel has an opaque inner wall and a closely spaced transparent outer wall, with a void in between. Puncture from the outside through the two walls provides seepage of the interiorly-carried liquid between the multiple walls to provide the look of spoilage.
