Publication number: 20240082157Abstract: The present disclosure relates to a formulation for a wide variety of poorly soluble drugs to improve bioavailability using a solid self-emulsifying drug delivery system. Compositions of the present disclosure can be used for improved delivery of hydrophobic or lipophilic pharmaceutical active ingredients, such as drugs, nutritional agents, cosmeceuticals, and diagnostic agents.Type: ApplicationFiled: January 19, 2022Publication date: March 14, 2024Applicant: SPI Pharma, Inc.Inventor: Graeme MACLEOD
-
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. PROPST
-
Publication number: 20230255891Abstract: The present invention relates to solid dispersions including, but not limited to, co-processed carbohydrates with different solubilities and concentrations, which have a microcrystalline plate structure. The solid dispersions, excipient systems and formulations of the present invention are highly compactable and durable and when compressed into solid dosage forms demonstrate uniform densification, low friability at low pressures, and and/or relatively constant low disintegration times at various hardnesses. The solid dosage forms of the present invention demonstrate superior organoleptics, disintegration, and/or robustness.Type: ApplicationFiled: April 28, 2023Publication date: August 17, 2023Applicant: SPI Pharma, Inc.Inventors: John Tillotson, Cecil Propst
