Patent number: 6899890Abstract: The present invention relates to a novel essentially pH neutral vaginal drug delivery system suitable for modified delivery of a therapeutically active material in the vaginal cavity. The vaginal drug delivery system comprises an essentially pH neutral emulsion having globules having two phases, an internal water soluble phase and an external water-insoluble phase or film, wherein the water-soluble interior phase contains a therapeutically active drug or drugs. One novel aspect of the vaginal drug delivery system is that the internal water soluble phase comprises an acidic buffered phase.Type: GrantFiled: March 20, 2002Date of Patent: May 31, 2005Assignee: KV Pharmaceutical CompanyInventors: Mitchell I.

Patent number: 5061520Abstract: Particles are enrobed or coated by introducing, to a spinning cup having an outwardly upwardly extending inner surface with an upper edge, a liquid coating material and particles of greater density than the coating material. The coating material and particles are introduced inboard of the peripheral surface, perferably in separate streams. The speed of rotation of the spinning cup is controlled to cause the coating material to climb up the surface but to stop short of the upper edge, and at the same time to cause the particles to travel through the coating material, be enrobed with the coating liquid, climb out of the liquid coating material, and be ejected over the upper edge. The spinning cup is symmetrical about a central vertical axis. It has a peripheral surface sloping outwardly upwardly, which surface can be stepped outwardly upwardly, and a control device is provided for controlling the speed of rotation of the spinning cup.Type: GrantFiled: October 5, 1990Date of Patent: October 29, 1991Assignee: KV Pharmaceutical CompanyInventor: Victor M.
