실험 절차

The Uncoated Dextromethorphan Resin Complex was prepared by first dissolving 95.42 g of dextromethorphan HBr in 0.8 L of purified water heated to 75-80° C., followed by the addition of 175.82 g AMBERLITE IRP-69 resin (anhydrous) under gentle mixing for 4 hours. At the completion, the suspension was allowed to settle, decanted and rinsed with purified water twice and dried in an oven maintained at 50° C. until moisture is around 5%. The dried resin complex was hand sieved through a 40 mesh screen.
