  • Publication number: 20150238429
    Abstract: Disclosed herein is a soft elastic capsule that includes an acid resistant, capsule shell that defines an encapsulated space having a predetermined volume, a liquid or semisolid fill comprising a first active ingredient located within the encapsulated space, and a first compressed tablet a having a minimal dimension of 2 mm, being located within the encapsulated space, unanchored to the capsule shell, and surrounded by the fill, said tablet comprising a second active ingredient that is substantially insoluble in the fill. A method of manufacturing a soft elastic capsule is also disclosed.

  • Patent number: 7887838
    Abstract: A film-forming composition comprising a hydrocolloid, a plasticizer, and water is described. A process and apparatus for producing a non-gelatin film comprising a hydrocolloid, a plasticizer, and water is also disclosed. The process includes combining at least one non-gelatin hydrocolloid, water, and at least one plasticizer into a substantially homogeneous film-forming composition comprising at least about 40 percent water by weight. A substantial portion of the water is then extracted from the film-forming composition to form a dried portion having a water content of less than or equal to about 25 percent by weight. The dried portion of the film-forming composition is formed into a film. A film produced according to the process preferably has a tensile strength at rupture of at least about 0.4 N/mn2, and a percent elongation of at least about 50 percent at rupture at room temperature.

  • Publication number: 20060029660
    Abstract: A film-forming hydrocolloid composition comprising kappa carrageenan, iota carrageenan, a bulking agent, plasticizer and water is described. The ratio of bulking agent to total carrageenan is from about 1:1 to 20:1. Kappa carrageenan is present in an amount of less than or equal to 50% by weight of total carrageenan present. To form the composition, all dry materials are mixed and added to a heated mixture of all liquid materials. The final mixture is heated until a composition free of particulate materials is formed. The formed composition can be cast or extruded into ribbons, films, sheets, tubes or the like, for encapsulating wet or dry materials including medicinal dosage forms, nutritional supplements, cosmetics, bath oils and gels, and paint balls.
