Procedure

75.0 g of methylephedrine hydrochloride was dissolved in 750 ml of deionized water, and 378.8 g of Amberlite IRP69 was added while stirring. The mixture was stirred for 1 hour to yield a methylephedrine-resin complex. Then, the complex was treated with PEG and coated with the diffusion barrier material similarly as in Example 1 to obtain a coated methylephedrine-resin complex.
