Enteric-coated capsule containing cationic nanoparticles for oral insulin delivery

The invention relates to an enteric-coated capsule containing cationic nanoparticles for oral insulin delivery, in particular to a type of cationic nanoparticle including a polycationic and mucoadhesive polymer and a biodegradable polymer, wherein each of the nanoparticles has positive surface charge and enhanced permeability for paracellular insulin delivery; the enteric-coated capsule further includes a pH-sensitive polymer as the coating. The enteric-coated capsule containing cationic nanoparticles, when being orally administered to a subject, are configured to prevent the acidic degradation of the active substance such as insulin before being released from said cationic nanoparticles to a specific absorption site along the gastrointestinal tract.

Enteric delivery of (-)-hydroxycitric acid

The present invention provides stable encapsulated (−)-hydroxycitric acid (“HCA”) dosage unit forms, uses thereof, as well as and methods of making the same. In particular, HCA and the salts, esters and amides of HCA according to the invention are delivered via enteric vehicles, such as enteric-coated tablets, and also enteric and enteric-coated capsules and soft gelatin capsules (softgels). Enteric-coatings may be applied externally to the HCA-containing dosage unit form or, in the case of capsules and soft gelatin capsules, the enteric compound also may be incorporated into the gelatin shell to yield an HCA-containing dosage unit form of the invention. The HCA-containing compositions are protected against acid degradation, lactonization and undesirable ligand binding in select environments. The invention provides HCA-containing dosage unit forms useful to prevent or reduce the symptoms associated with a disease, disorder or condition such as obesity, weight gain, hunger, hyperlipemia, and postprandial lipemia.

Capsule type slow-release formaldehyde scavenger and preparation process thereof

ActiveCN113181767AContinuous adsorption purificationSatisfy Absorption ClearanceMaterial granulation and coatingGas treatmentSustained Release CapsuleTitanium oxide
The invention discloses a capsule type slow-release formaldehyde scavenger and a preparation process thereof, and belongs to the technical field of formaldehyde scavenging. The capsule-type slow-release formaldehyde scavenger comprises a slow-release carrier pellet core and a thinly coated capsule. The capsule type slow-release formaldehyde scavenger is prepared from the following raw materials in parts by mass: 40-70 parts of an activated carbon base material, 30-60 parts of a titanium dioxide base material, 5-10 parts of a forming material, 2-20 parts of a sustained-release material, 1-5 parts of a plasticizer and 0.5-1.5 parts of an anti-sticking agent. The thinly coated capsule is a polytetrafluoroethylene breathable waterproof thin coating, and the preparation process comprises matrix preparation, material mixing, granulation, sustained-release liquid preparation and coating. The titanium dioxide oxide is mixed in the activated carbon matrix, and after the activated carbon, the forming material and the sustained-release material are fused, the sustained-release capsule can continuously adsorb and purify formaldehyde under photocatalysis, and a surface film can isolate external water vapor from soaking, so that the sustained-release efficiency is improved, the coating placement time is remarkably prolonged, and the continuous purification capability on formaldehyde is met.

Injection molding method and device for preparing large-size high-temperature-resistant and high-pressure-resistant expansion coated capsule from ultrahigh-viscosity silicone rubber

The invention discloses an injection molding method and device for preparing a large-size high-temperature-resistant and high-pressure-resistant expansion coated capsule from ultrahigh-viscosity silicone rubber. Part of the composite material has a large-size complex internal structure, so that the composite material has difficulties in preparing and demoulding processes, and the problems of uneven mixing, poor storage and the like of the double-component high-viscosity rubber in a rubber injection process are extremely prone to occurring during injection molding. The invention provides the injection molding method and device for preparing the large-size high-temperature-resistant and high-pressure-resistant expansion coated capsule from the ultrahigh-viscosity silicone rubber in order tosolve the problems, and relates to a two-component resin tank, an extrusion device, a vacuum device, a mixer and a mold. A material A and a material B are independently stored in the material storagebox, a vacuum device is connected into the material storage box, the material A and the material B in a ratio of x:y can be extruded into the mixer through an extrusion device during use, the mixed material passes through the mutichannel mixer during injection into the mold, rotating blades are installed in the mixer, and finally the mixed material is injected into the mold. According to the invention, rubber products with certain thickness, temperature resistance, long size and anisotropy can be produced.
