Publication number: 20230330032Abstract: A composition comprising a core material, having a taste value and polymeric coating. The polymeric coating substantially surrounds the core material and comprises a cationic polymer and optionally an anionic polymer. The polymeric coating has a uniform thickness ranging from 2 ?m to 20 ?m. The composition provides release of a portion of the core material which is taste masked over a time period ranging from 0.5 minute to 2 minutes in the oral cavity and provides a modified-release of the remaining core material in a gastrointestinal tract.Type: ApplicationFiled: June 21, 2023Publication date: October 19, 2023Applicant: SPI PHARMA, INC.Inventors: Diane GOLL, Cecil W.
