摘要: Benzoyl peroxide intended for topical application is incorporated in novel formulations in which it is retained as impregnants inside the pores of porous solid particles or microspheres. The pores form a continuous network open to the exterior of the particles, permitting outward diffusion of the benzoyl peroxide impregnant at a controlled rate depending on the pore size. The impregnated particles are prepared by impregnation of preformed particles with the benzoyl peroxide.

摘要: Ionic compositions comprise an active ingredient absorbed within a network of internal pores defined by a plurality of polymeric particles. The particles are preferably crosslinked polymeric beads having a diameter in the range from about 5 to 100 microns and a surface charge density from about 0.1 to 10 meq/qm hydrogen ion capacity. The active ingredients are released from the ionic polymer beads over time when orally administered, applied to a keratinic material, typically human skin or hair or otherwise delivered to a target environment. The use of a cationic charge promotes adhesion of the beads to the keratinic material.

摘要: Diseases of the colon are treated by oral ingestion of a unit dosage form containing a plurality of porous microscopic beads, the pores containing an active agent or drug and plugged with a polysaccharide that is chemically degradable by colon-specific bacteria. The dosage form further contains a coating of an enteric material that remains intact until the dosage form reaches the colon.

摘要: Flavored food and pharmaceutical compositions include one or more flavor additives incorporated within polymeric particles, usually within an internal pore network defined by individual polymeric particles. The polymeric particles are, in turn, dispersed within and/or over a surface of an orally-deliverable matrix material, which is usually a solid or semi-solid substrate. In the case of chewable compositions, the flavor additives will be released into the orally-deliverable matrix material as the composition is chewed and held in the mouth, thus prolonging the flavor of the composition. In the case of dried powders and mixes, the flavor will typically be made available as the product is consumed or be released into the matrix material as the composition is further processed. When two flavors are combined with the polymeric particles, the relative amounts of the additives can be selected to provide simultaneous release and exhaustion of the additives.

摘要: Transdermal drug delivery systems comprise a backing or enclosure having a matrix layer which incorporates a drug and a percutaneous enhancer for the drug. The percutaneous enhancer and/or drug will be contained within polymeric particles dispersed through the matrix layer, where the polymeric particles define pore networks which are sized to release the enhancer and/or drug into the matrix layer at rate(s) selected to provide for a desired rate of drug penetration. By isolating the enhancer within the polymeric particles, adverse interactions between the enhancer and the matrix layer and/or the drug can be minimized. Moreover, the release rate of the enhancer into the matrix layer can be carefully controlled, which in turn controls the penetration rate of the drug into the treated host.
