Procedure

A casting solution was prepared containing 4.0% CMC and 1.0% erythritol. A 10.0 mg aliquot of scopolamine HCl was dissolved into 50 g of the casting solution thereby yielding a scopolamine HCl concentration of 200 μg/g of the casting solution. A 1.2543 g amount of the casting solution containing the drug was equally divided between the three wells of the sample BP strip. PAM® was employed as a release agent. After 45 minutes in the IR drying tunnel the recovered weight was 105% of the theoretical NVS. The resulting films easily released from the casting well and were clear and flexible. Each film swatch averaged 22 mg and contained 8.4 μg of scopolamine HCl.
