摘要:
This patent pertains to the use of debranched starch in the preparation of pharmaceutical pellets by extrusion spheronization. Such excipients are useful in any dry dosage form, including tablets and capsules, for either immediate or sustained release.
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 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 dry powder composition for poultry vaccination via inhalation comprising an effective amount of a poultry vaccine agent, and a supporting amount of carriers for said poultry vaccine agent, said carriers comprising a combination of a reducing or non-reducing sugar and a biocompatible polymer, said dry powder composition being in the form of particles having an average particle size from 2 to 30 μm and a particle size polydispersity from 1.1 to 4.0. This invention also relates to a method for producing said dry powder compositions and a system for vaccination of poultry by inhalation.
摘要:
The present invention in general relates to an intravaginal delivery system as well as uses thereof and methods for manufacturing and use of the same. In particular the present invention relates to an intravaginal delivery system for the controlled release of one or more organic acids, such as lactic acid; said intravaginal delivery system being characterized in that it comprises a combination of ethylene vinyl acetate (EVA) copolymers and carboxylic polymers, such as for example methacrylic acid-methacrylic ester copolymers.

摘要:
The present invention discloses a composition comprising a polyelectrolyte complex and a polyol, characterised in that said polyol is in amorphous form. Optionally, the composition further comprises one or more drugs, wherein each drug has a molecular weight of at least 1000 Dalton. Said compositions are obtainable by spray-drying. The compositions may be prepared in particle form and as a suspension of particles. Pharmaceutical compositions are also provided for use in extracellular drug delivery. Pharmaceutical compositions are also provided that exhibit a controlled dual drug release.
