摘要:
A pharmaceutical or veterinary granule composition in the form of a mixture consisting essentially of: (i) at least one drug classifiable as Class II or Class IV of the Biopharmaceutical Classification System, wherein said drug (i) constitutes from above about 20% to 50% by weight of the composition, said pharmaceutical or veterinary granule composition providing a drug release of at least 70% within 10 minutes in water, (ii) a first excipient being a maltodextrin representing from 40% by weight to 85% by weight of said composition, (iii) a wetting amount of a second excipient being a polyethylene glycol having a weight number molecular weight between 300 and 5,000, said second excipient comprising a solid fraction and a liquid fraction, and representing from 15% to 40% by weight of said composition, and optionally one or more pharma-ceutically acceptable fillers selected from the group consisting of hydrocolloids, glidants, lubricants, surfactants and diluents, wherein the weight ratio of said first excipient (ii) to said second excipient (iii) is in a range from 1:1 to 5:1.

A pharmaceutical or veterinary granule composition in the form of a mixture consisting essentially of: (i) at least one drug classifiable as Class II or Class IV of the Biopharmaceutical Classification System, wherein said drug (i) constitutes from 0.5% to 20% by weight of the composition, and excipients, said pharmaceutical or veterinary granule composition providing a drug release of at least 70% within 10 minutes in water, (ii) a first excipient being a maltodextrin representing from 40% by weight to 80% by weight of said composition, (iii) a wetting amount of a second excipient being a polyethylene glycol having a weight number molecular weight between 300 and 5,000, said second excipient comprising a solid fraction and a liquid fraction, and representing from 15% to 40% by weight of said composition, and optionally one or more pharmaceutically acceptable fillers selected from the group consisting of hydrocolloids, glidants, lubricants, surfactants and diluents, wherein the weight ratio of said first excipient (ii) to said second excipient (iii) is in a range from 1:1 to 5:1.
摘要:
This invention provides a process for preparing a solid dosage form, comprising:—preparing an aqueous slurry, solution or suspension of (a) a powder material, and (b) a mixture of one or more polyols and one or more maltodextrins, and—spray drying the resultant aqueous slurry, solution or suspension, thereby obtaining particles which are directly compressible into a solid dosage form being able to disintegrate in an aqueous medium within no more than 15 minutes.
摘要:
A beeswax mimetic substance is described which comprises or consists essentially of a synthetic or semisynthetic wax, in particular a microcrystalline wax. The wax preferably has a relatively narrow range of mean carbon chain length. An apiculture accessory using the wax and a method of operating beehives using the wax to reduce disease and pests in beehives is described.
摘要:
An in vivo and an in vitro toxicity test method is described using an organisim or part of an organism from the class Gastropoda. The method is particularly useful for toxicity testing of chemical substances intended for application to human or animal mucosa, such as the intestinal, vaginal, buccal, nasal or respiratory mucosa. The test method may be used both as a screening test and also as a quantitative toxicity test suitable for ranking the toxicity of chemical substances.
摘要:
The invention provides bioadhesive composition having increased bioadhesive properties, decreased irritation, and the capacity for higher drug loading. The compositions of the invention comprise intimate mixtures of a polysaccharide and a polycarboxylated polymer, and optionally also an absorption enhancer.
摘要:
Biologically inactive cushioning beads comprise at least one compressible cushioning component consisting essentially of a microcrystalline hydrocarbon wax or a natural wax, the said wax being at least 30% by weight of the biologically inactive cushioning beads. Such beads are useful for making solid shaped articles containing biologically active ingredients by compression.
摘要:
This invention relates to a method of producing a bioadhesive composition comprising the steps of preparing a solution of a solvent and a polymer mixture wherein the polymer mixture comprises at least one natural or synthetic polycarboxylated polymer and at least one polysaccharide; drying the solution to form a solid; and heat treating the solid to effect cross-linking and to form the bioadhesive composition.
摘要:
A solid preparation for a substantially immediate release of an active agent with low or very low solubility, which contains the active agent dissolved in a solubilizer, said dissolved active agent being contained in solid particles which are agglomerated into a system of agglomerated particles which is not a matrix or gelling forming agent.
摘要:
This invention relates to xanthohumol-based compositions, yielded in a hot-melt extrusion process (HME) using one or more water-soluble nutritionally and/or cosmetically acceptable thermoplastic polymers, such as selected from hydroxypropylmethyl-cellulose (HPMC), a vinylpyrrolidone-vinyl acetate copolymer, and combinations thereof. The present invention also relates to topical and oral formulations comprising such extruded xanthohumol-based compositions, as well as the use of one or more water-soluble nutritionally and/or cosmetically acceptable thermoplastic polymers in a hot-melt extrusion process of xanthohumol.
