POROUS SHAPED DELIVERY DEVICES AND METHOD OF PRODUCING THEREOF |
摘要 |
High strength, high porosity delivery devices have a shaped surface and disintegrate quickly in an aqueous medium. The devices can be prepared by disposing a formulation in a die to form a frozen predevice. A second die is contacted with the frozen formulation surface at a pressure and temperature for a time sufficient to locally momentarily liquify and shape the device surface. The shaping is followed by lyophilization. |
