Abstract:
Multiphasic nano-components (MPNs) having at least two phases and at least one active ingredient are provided. The MPNs can be used in various methods for medical diagnostics or with pharmaceutical, personal care, oral care, and/or nutritional compositions, for example, in oral care, hair, or skin products. The MPNs can be designed to have targeted delivery within an organism, while providing controlled release systems or combining incompatible active ingredients. Further, the MPNs can be used as biomedical coatings (such as anti-microbial coatings), or anti-corrosive coatings, bioimaging probes with combined diagnostic and therapeutic use, and fragrance release systems, among others. The MPNs can be formed by electrified jetting of polymers.
Abstract:
Sustained release spherical or non-spherical pellets comprising (a) an active ingredient (b) a wax-like agent, and (c) a spheronizing agent are provided. Oral dosage forms comprising said pellets and methods for preparing and using such pellets and dosage forms are also provided.
Abstract:
One aspect of the present invention relates to a granulate having a volume weighted mean diameter of 1-200 m and containing: at least 0.1 wt.% of a pharmaceutically active substance; at least 10 wt.% of emulsifier 0-89.9 wt.% of a water-dispersible saccharide; the combination of the pharmaceutically active substance, the emulsifier and the water-dispersible saccharide together represening at least 60 wt.% of the granulate; wherein the granulate is monophasic or wherein the granulate comprises a dispersed phase containing the pharmaceutically active substance, said dispersed phase having a volume weighted mean diameter of less than 300 nm. Another aspect of the invention relates to a process for the preparation of said granulate containing a pharmaceutically active substance, which process employs.
Abstract:
L'invention concerne une nouvelle méthode pour formuler des principes actifs pharmaceutiques de manière à les protéger lors de l'ingestion orale et permettre de contrôler la libération du principe actif dans l'intestin. Elle repose sur l'utilisation d'émulsions acryliques et épaississantes à pH supérieur à 5 et contenant des groupements hydrophobes, pour encapsuler des principes actifs pharmaceutiques dans le but de favoriser leur franchissement de la barrière gastro-intestinale tout en maîtrisant la cinétique de libération desdits principes actifs.
Abstract:
A process for manufacturing multiparticulate pharmaceutical compositions using a roller compactor. The process is particularly useful for producing minitablets without the need of the use of a tablet press. The roller compactor features rolls having depressions or molds in the surface. Upon compaction of pharmaceutical blend, the minitablets are formed by the depressions in the roller surfaces.
Abstract:
A pharmaceutical composition comprising Angiotensin II Antagonist, wherein the pharmaceutical composition is prepared by wet granulation. A pharmaceutical composition comprising Angiotensin II Antagonist and one or more diuretics, wherein the pharmaceutical composition is prepared by wet granulation. A pharmaceutical composition prepared by wet granulation comprising an active agent comprising an effective amount of Angiotensin II Antagonist and pharmaceutically acceptable additives, wherein the active agent is present in an amount less than 35% by weight based on the total weight of the pharmaceutical composition.
Abstract:
Methods of producing microparticles, and especially chitin microparticles (CMP), are disclosed that involve reducing the size of (larger) particles using a (high shear) microfluidising instrument.
Abstract:
A process for the precipitation of an organic compound comprising mixing simultaneously introduced streams of a solution and a precipitation agent in a chamber using a mechanical stirrer in the presence of an amphiphilic polymer. The process may be operated in a continuous manner and is particularly useful for providing low solubility organic compounds (e.g. pharmaceuticals) in readily dispersible, nano-sized particulate form up to manufacturing scale.
Abstract:
Compositions containing polymeric micro- and nanopartioles with non- spherical shapes and methods for making and using such particles are described herein. The particles have one or more dimensions ranging from about 5 nm to about 100 μm, preferably about 100 nm to 10 μm. The particles can have any of a wide variety of non-spherical shapes. The particles are generally formed by manipulation of spherical particles embedded in a polymeric film. A wide variety of resulting shapes can be made, The resulting shape is a function of whether the films are manipulated in a first and/or second dimension, and the processes used to liquefy the microparticles. Variations of the method of manufacture may be used to generate particles having the desired shapes in large, reproducible quantities. The resulting non-spherical shaped particles can be used to alter uptake by phagocytic cells and thereby clearance by the reticuloendothelial system.
Abstract:
Methods are provided for drying a particle. Specifically, there is provided a spray-dried diketopiperazine-insulin particle formulation having improved aerodynamic performance and in which the active agent is more stabile and efficiently delivered as compared to that of the lyophilized diketopiperazine-insulin formulation. The dry powders have utility as pharmaceutical formulations for pulmonary delivery.
