  • Patent number: 5478571
    Abstract: A novel process for the preparation of pharmaceutical compositions involving the stabilization of the active drug(s) through the reduction of residual alcohol present in a drug/carrier blend. The presence of residual alcohol in dried pharmaceutical compositions adversely affects many drugs which must be initially dissolved therein in order to achieve uniform distributions throughout the excipient carrier materials. Wherein not previously possible, its removal is achieved utilizing precise processing parameters in which water lost during the drying process is replenished during blending in a conventional solids processor.
