摘要:
In accordance with the present invention, these and other objects are achieved by a pharmaceutical composition comprised of 1) a pharmaceutical core which is further comprised of a pharmaceutically active dose of a compound and, 2) a microencapsulating polymer which coats the pharmaceutical core and is capable of taste-masking the active compound. The polymer coating maintains its integrity, i.e., does not fracture and release active when tabletted and/or chewed, and can provide immediate release of the active compound in the stomach, or alternatively, in certain embodiments, can release the active agent in the upper intestinal tract or in sustained release fashion. Additionally, the polymeric coating compositions or the pharmaceutical core may contain diluents, fillers, bulking agents, and plasticizers. The polymeric coatings may also contain pigments and opacifiers to promote compliance and enhance the storage stability of light sensitive active agents.
