摘要:
An apparatus for wet granulating a powder material comprises:—a barrel having a granulation chamber and being provided with a first inlet (1) for receiving said powder material and for supplying it to said granulation chamber and with a second inlet (2) for receiving a granulating liquid and for supplying it to said granulation chamber, said granulation having an aperture (9) for discharge of granules from said barrel, and—a transporting means (S) for advancing said powder material toward the end of said granulation chamber while granulating it with the aid of said granulating liquid, said transporting means (S) comprising a first transport zone (4) at its rear end, an agglomeration zone (5) downstream from the first transport zone (4) and a second transport zone (8) at its front end, said first inlet (1) and said second inlet (2) being positioned above the first transport zone (4), wherein said aperture (9) has a shape tightly fitting the terminal portion of the transporting means (S) for directly discharging said granules from the granulation chamber. The apparatus is useful for continuously wet granulating biologically-active ingredient formulations, chemicals, detergents and foodstuffs.

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.
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.
