Abstract: A non-toxic, edible, enteric film coating, dry powder composition for use in making an aqueous enteric suspension which may be used in coating pharmaceutical tablets comprises a) an acrylic resin, said resin comprising i) from 20 to 85 percent by weight of at least one alkyl acrylate or alkyl methacrylate moiety, ii) from 80 to 15 percent by weight of at least one vinyl or vinylidene moiety having a carboxylic acid group capable of salt formation, and iii) from 0 to 30 percent by weight of at least one other vinyl or vinylidene moiety copolymerizable with i) and ii), b) an alkalizing agent capable of reacting with the acrylic resin such that, after reaction, 0.1 to 10 mole percent of the acidic groups in 1a-ii) are present in the salt form, and c) a detackifier.

Abstract: A non-toxic edible enteric film coating dry powder composition for use in making an aqueous enteric coating suspension which may be used in coating pharmaceutical tablets and the like comprises an enteric film forming polymer, a detackifier, a viscosity modifier, and an alkalizing/anti-coagulating agent. Advantageously, the inventive dry powder compositions may include a solid plasticizer, a lubricant, an anti-caking agent, a liquid plasticizer, and a pigment.

Abstract: A composition for agricultural and other actives, comprising a finely-divided particulate combination of microcrystalline cellulose, at least one nitrogen compound such as urea, an ammonium sulfate or phosphate and, optionally, a suspending agent for the micro-crystalline cellulose. The composition can be compacted to form shaped, solid dosage forms such as tablets which disintegrate rapidly in an aqueous medium.

Abstract: Freeze-dried polymer latices, which can be reconstituted in water to give aqueous polymer dispersions having high polymer solids content, are described. The reconstituted polymer dispersions are useful in preparing sustained-release drug formulations, particularly of water-soluble drugs, by the wet granulation method without over wetting.

Abstract: A particulate coprocessed microcrystalline cellulose and calcium carbonate composition having the respective components present in a weight ratio of from about 75:25 to 35:65. The composition is useful as a pharmaceutical excipient.The coprocessed composition is prepared by forming a well-dispersed aqueous slurry of microcrystalline cellulose and calcium carbonate and then drying the slurry, preferably by spray drying, to yield a particulate product.
