Pharmaceutical composition for the treatment of acute disorders

Abstract

A pharmaceutical composition for the treatment of acute disorders is described. The composition comprises an essentially water-free, ordered mixture of at least one pharmaceutically active agent in the form of microparticles which are adhered to the surfaces of carrier particles which are substantially larger than the particles of the active agent or agents, and are essentially water-soluble, in combination with the bioadhesion and/or mucoadhesion promoting agent. The invention also relates to a method for preparing the composition and to the use of the composition for the treatment of acute disorders.

What is claimed is: 
     
         1 . A pharmaceutical composition in the form of a tablet sized for placement under a tongue, wherein the composition comprises
 (a) water-soluble carrier particles having exterior surfaces,   (b) microparticles of buprenorphine or a pharmaceutically-acceptable salt thereof, wherein said microparticles are smaller than the carrier particles and are admixed with the carrier particles, and   (c) particles of a bioadhesion and/or mucoadhesion promoting agent consisting essentially of a polymer that swells when brought into contact with saliva, admixed with the carrier particles,   wherein the microparticles of buprenorphine or a pharmaceutically-acceptable salt thereof are presented at the exterior surfaces of the carrier particles.
