Abstract: Process for preparing an oral rapidly disintegrating dosage form of a hydrophobic pharmaceutically active substance comprising forming a suspension of the hydrophobic pharmaceutically active substance in a solvent containing a pharmaceutically acceptable surfactant together with a water-soluble or water-dispersible carrier material, forming discrete units of the suspension and removing solvent from the discrete units under conditions whereby a network of the carrier material carrying a dosage of the hydrophobic pharmaceutically active substance is formed.

Abstract: An improved method for manufacturing freeze dried pharmaceutical tablets in blister packs is disclosed. Liquid dosages are introduced into a multilayer laminated blister sheet having an impermeable intermediate layer (14) that is positioned between first and second outer layer (16, 18) each of which has substantially the same coefficient of thermal expansion. The properties of the outer layers of the blister sheet are such that there are no inter-layer stresses that will cause curvature of the blister sheet when it is subjected to temperature changes during the freezing and freeze drying steps. Following the introduction of the dosages into the depressions (10) of the blister sheet, the dosages are frozen and freeze dried. A lidding sheet (32) is then attached to the blister sheet to seal the solid dosages into the blister pack.
