Procedure

40.0 g of N-pyrrolidone, 20.0 g of propranolol HCl and 20.0 g of polyvinylpyrrolidone with a K value of 90 are dissolved in 40.0 g of demineralized water. This solution is incorporated into 333.3 g of 30% strength polyvinyl acetate dispersion of the invention while stirring. A 200 μm knife is used to spread this mixture onto a 40 μm-thick polyester sheet, which is then dried at 60° C. The spreading process is repeated once more to increase the layer thickness. After covering the polymer layer with a siliconized released liner it is possible to punch out any desired shapes.
