Summary:PCT No. PCT/US92/09321 Sec. 371 Date Sep. 15, 1994 Sec. 102(e) Date Sep. 15, 1994 PCT Filed Nov. 6, 1992 PCT Pub. No. WO93/18757 PCT Pub. Date Sep. 30, 1993.An efficient method for making high strength, highly porous, fast dissolving delivery devices. The method comprises mixing a formulation comprising menthol, a water-soluble, menthol-soluble polymer, and an active agent at a temperature such that the menthol is substantially molten. The formulation is disposed in a mold, solidified and the menthol is sublimed from the solidified molded formulation. Preferably, the solidification occurs at a temperature sufficient to provide a substantially amorphous menthol structure.
