A gastroretentive composition comprises a mixture comprising an active ingredient component and an excipient component. The excipient component comprises a first water-soluble reaction product produced from a precursor comprising a vinyl group, and a copolymer of a polyalkylene glycol and a second water-soluble reaction product produced from a precursor comprising a vinyl group. A method of forming the gastroretentive composition comprises the steps of providing the active ingredient component and the excipient component, and mixing the active ingredient component and the excipient component to form a mixture. The mixture is aggregated to form an aggregation that is dry granulated to form a plurality of granules. The plurality of granules is processed to form the gastroretentive composition.

A method for formation of micro-prilled poloxamer particles is disclosed. The particles find special use in pharmaceutical formulations. The process involves use of atomizing nozzles at higher than normal pressure atomizing gas, high atomizing gas temperature, use of high feed temperatures to reduce the viscosity of the poloxamer and optionally sieving after prill formation in prilling towers. The poloxamer particles are spherical and preferably have an average nominal diameter of less than or equal to 106 microns. The process is very cost effective and rapid.

A medicament carrier composition includes a medicament and a polymer component including a polyvinylpyrrolidone having a weight average molecular weight of at least 700,000 g/mol. The medicament carrier composition has a viscosity of from 500 to 5,000 cps at 250 C, is substantially free of cellulose, and includes an auxiliary polymer. The medicament carrier composition is used to form a film that is also substantially free of cellulose. The film has a consistent thickness and size, and an increased flexibility and increased moisture resistance due to the polyvinylpyrrolidone. The medicament carrier composition is also used in a method of forming the film. The method includes the steps of providing the medicament and the polymer component. The method also includes the step of combining the polymer component and the medicament to form the medicament carrier composition. The method further includes the step of drying the medicament carrier composition to form the film.

A directly tabletable ibuprofen formulation comprising a) 50-99% by weight of crystalline ibuprofen, b) 1-15% by weight of a finely divided excipient with a surface area of at least 100 m/g, and c) 0-40% by weight of further excipients, with the proviso that the total amount of components a) to c) corresponds to 100% by weight, where at least 50% of the surface of the ibuprofen crystals are covered with the finely divided excipient.
