Patent number: 6465016Abstract: Pharmaceutical compositions containing solid cyclic oligopeptide cyclosporine microparticles are prepared by applying energy input to solid cyclic oligopeptide cyclosporine in the presence of phospholipid and one or more non-ionic, anionic or cationic second surface modifiers. The microparticles consist essentially of a solid cyclic oligopeptide cyclosporine core coated with a combination of phospholipid and at least one second surface modifier. The combination of phospholipid and second surface modifier(s) provide volume-weighted mean particle size values of solid cyclic oligopeptide cyclosporine particles that are about 50% smaller than cyclic oligopeptide cyclosporine particles produced in the presence of the phospholipid and without the presence of the second surface modifier(s) using the same energy input.Type: GrantFiled: December 29, 2000Date of Patent: October 15, 2002Assignee: Research Triangle PharmaceuticalsInventors: Indu Parikh, Robert A.
