Definitions

  • the present invention relates to new, multi-part, capsules for pharmaceutical preparations intended for oral administration of two incompatible drugs.
  • Capsules with pharmaceuticals are widely used in the treatment and diagnosis of diseases.
  • Hard capsules or bivalves consist of two cylindrical parts telescopically inserted into each other: a body with a hemispherical base and a lid of the same shape, but shorter. The inner diameter of the lid is actually equal to the outer diameter of the housing. When connected, two parts make up a container of standard sizes that are filled after passing through the entire molding process cycle and gaining rigidity.
  • Capsules are usually made from gelatin.
  • the capsules are made from well-digestible water-soluble plastics by humans, which, when taken orally, release the active ingredients in certain sections of the gastrointestinal tract.
  • EP 0 460 921 describes two-part capsules of chitosin and starch, cereal flour, oligosaccharides, methyl acrylate, methacrylic acid, acetate, succinate or hydroxypropyl methyl cellulose phthaleate.
  • the material of the capsule is characterized in that its contents are released only in the large intestine.
  • GB 938828 describes capsules for radioactive substances used in therapy or diagnosis. Such capsules are made from water-soluble gelatin, methyl cellulose, polyvinyl alcohol or non-toxic water-soluble thermoplastics.
  • RU 961 15307 A (10.27.1998 PCT GB 94/02703, A61 K 9/48) claims a pharmaceutical form in the form of two-phase capsules comprising a capsule having one compartment containing at least two filling compositions, characterized in that it is prevented mixing compositions with each other.
  • the two fill compositions are separated by a physical partition that contains an additional fill composition of a material different from the material of the capsule.
  • the material of the partition contains a material having a temperature melting 25 ° C or 37 ° C.
  • the pharmaceutical form may include a first filling composition containing a pharmaceutically active substance for a short release during non-parenteral administration, and a second filling composition containing a pharmaceutically active substance for a sustained release during non-parenteral administration.
  • the pharmaceutical form may include a first filling composition containing a biologically active substance, and a second filling composition containing a substance adapted to adjust the intestinal pH to a pH of from 7.5 to 9.

  • acetylphthalyl cellulose is introduced into the capsule mass or an enteric film coating is applied to the surface of the capsule.
  • Prologged hard gelatine capsules are prepared by introducing special ingredients (acrylic polymers, cellulose derivatives) into the product filler. Used combinations of substances prevent the rapid release of the active components of the capsule.
  • the capsule is filled as follows.
  • the housing 1 is filled with a metered amount of one medicine, tightly telescopically coaxially fit a septum 3 on it with the open end, then the lid is filled with a metered amount of another incompatible medicine and the housing is sealed telescopically coaxially coaxially with a sealed end.

Abstract

La présente concerne de nouvelles capsules pour produits pharmaceutiques constituées de deux parties et destinées à l'administration orale de deux médicaments incompatibles. La capsule pour deux médicaments incompatibles comprend un enrobage solide se présentant comme deux parties corps et capuchon, reliées coaxialement de façon télescopique, qui possèdent des parois latérales cylindriques, une extrémité ouverte et une région d'extrémité fermée, les surfaces cylindriques des parois latérales ont une longueur égale, et la région de l'extrémité fermée possède une forme d'hémisphère, qui se distingue en ce que la capsule comprend une paroi dotée d'un fond pour obturer l'extrémité ouverte du corps qui a été doté d'une saillie dont le diamètre externe est égal au diamètre interne de la paroi. La capsule peut être solvable dans l'estomac ou les intestins, avec une libération prolongée du médicament à partir d'une des parties, ou une partie de la capsule est solvable dans l'estomac et l'autre est solvable dans les intestins.
