An edible orally disintegrating tablet dosage form containing an unpalatable acidic active pharmaceutical ingredient, particularly ketoprofen, and an ion exchange resin as a primary taste masking agent, along with an optional alkaline agent and further optionally containing one or more secondary taste masking agents is provided. The edible orally disintegrating tablet dosage matrix is formed from at least one water soluble or miscible polymer(s). The optional secondary taste masking ingredients include one or more of flavoring agent(s), sweetener(s), cooling sensation agent(s), and taste receptor blocker(s). The inventive dosages minimize or completely mask the bitterness, burning sensation and throat irritation associated with many acidic active pharmaceutical ingredients. Methods for preparing the inventive edible oral film strip dosage forms are disclosed, as well as their method of administration.

A bone-regeneration material that contains calcium phosphate particles in a biodegradable fiber containing PLGA by using electrospinning. A PLGA resin is heated in a kneader to soften until the viscosity of the resin becomes 10.sup.2 to 10.sup.7 Pa.Math.s. A powder of calcium phosphate fine particles is added and mixed with the softened PLGA resin, while the blade of the kneader rotates. The mixture is kneaded by applying thermal and mechanical energy to the mixture through the continuous rotation of the blade of the kneader in the heated state, and aggregations of the calcium phosphate fine particles are disintegrated to prepare a composite in which the calcium phosphate fine particles are dispersed in the PLGA resin. The composite is dissolved in a solvent to prepare a spinning solution. Electrospinning is performed on the spinning solution to manufacture biodegradable fibers having therein the calcium phosphate fine particles substantially uniformly dispersed.

A method of manufacturing bulked continuous carpet filament from recycled polymer. In various embodiments, the method includes: (1) reducing recycled polymer material into polymer flakes; (2) cleansing the polymer flakes; (3) melting the flakes into a polymer melt; (4) removing water and contaminants from the polymer melt by dividing the polymer melt into a plurality of polymer streams and exposing those streams to pressures below 5 millibars; (5) recombining the streams; and (6) using the resulting purified polymer to produce bulked continuous carpet filament.

A system for manufacturing bulked continuous carpet filament that is adapted for providing a polymer melt and dividing the polymer melt into a plurality of streams (e.g., at least six or eight streams) to increase a surface area of the polymer melt. The plurality of streams is then exposed to a pressure that is below approximately 5 millibars. The streams are then recombined into a single polymer stream and formed into bulked continuous carpet filament. In various embodiments, an extruder, such as a multi-screw extruder, is used to divide the polymer melt into the plurality of streams.
