Patent number: 8415329Abstract: Compositions of submicron- to micron-sized particles of water-insoluble biologically active substances that are stabilized by thermoprotecting agents, can be terminally steam sterilized without any significant increase of mean particle size. These compositions display markedly reduced heat-induced coagulation, flocculation, or particle size growth during the terminal steam sterilization process.Type: GrantFiled: May 28, 1999Date of Patent: April 9, 2013Assignee: Jagotec AGInventor: Awadhesh K. Mishra

Publication number: 20110244032Abstract: Rapidly dispersing solid dry therapeutic dosage form comprised of a water insoluble compound existing as a nanometer or micrometer particulate solid which is surface stabilized by the presence of at least one phospholipid, the particulate solid being dispersed throughout a bulking matrix. When the dosage form is introduced into an aqueous environment the bulking matrix is substantially completely dissolves within less than 2 minutes thereby releasing the water insoluble particulate solid in an unaggregated and/or unagglomerated state. The matrix is composed of a water insoluble substance or therapeutically useful water insoluble or poorly water soluble compound, a phospholipid and optionally also at least one non-ionic, anionic, cationic, or amphipathic surfactant, together with a matrix or bulking agent and if needed a release agent. The volume weighted mean particle size of the water insoluble particle is 5 micrometers or less.Type: ApplicationFiled: May 10, 2011Publication date: October 6, 2011Applicant: Jagotec AGInventors: Indu Parikh, Awadhesh K.

Patent number: 7097849Abstract: Irritation upon injection of a formulation containing propofol is reduced or substantially eliminated by administering a stable, sterile, and antimicrobial aqueous dispersion comprising a water-insoluble microdroplet matrix of mean diameter from about 50 nm to about 1000 nm consisting essentially of about 1% to about 15% of propofol, up to about 7% of a propofol-soluble diluent, and about 0.8% to about 4% of a surface stabilizing amphiphilic agent. The aqueous phase includes a pharmaceutically acceptable water-soluble polyhydroxy tonicity modifier. The propofol-containing dispersion is devoid of additional bactericidal or bacteriostatic preservative agents.Type: GrantFiled: August 18, 1999Date of Patent: August 29, 2006Assignee: Jagotec AGInventors: Awadhesh K.
