Esomeprazole magnesium trihydrate (10 g) was dissolved in a mixture of dichloromethane (50 ml) and ethanol (70 ml) at 25-30° C. Any undissolved material was filtered off. The clear solution thus obtained was spray dried with an inlet temperature of 70-80° C. and an outlet temperature of 22-42° C. The solid was further dried under vacuum at 60-65° C. for 14 to 15 hours to yield 5.82 g of esomeprazole magnesium of amorphous form.
