  • Publication number: 20230330026
    Abstract: A tablet formed from a pre-lyophilization solution has a void in its bottom surface, with a void height that is about 60% to 100% of a depth of the tablet. A pharmaceutical dosage form includes a blister sheet having one or more cavities, each having a protrusion extending upwardly from the cavity floor, with a tablet formed in the cavity by lyophilization of a pre-lyophilization solution in each such cavity. The protrusion is a cylinder or tapered cylinder and the void has a corresponding shape. A film overlays the blister sheet to seal the tablet in the blister sheet cavities.

  • Publication number: 20220183986
    Abstract: A method and system of forming a pharmaceutical dosage form within a portion of a blister packaging. The method includes the steps of providing a blister packaging for the dosage form with depressions. A predetermined amount of a drug-containing powder material comprising drug-containing particles is deposited into a substantially uniform powder layer within the depressions. A binding liquid is then deposited in a pattern on the powder layer within the depressions, to bind the particles of the powder layer and form an incremental wetted layer, Excess solvent in the binding material can be removed to form an incremental bound layer. These steps are repeated in sequence at least one or more times to form the pharmaceutical dosage form within the blister packaging.
