Study on pilot manufacture of aspirine microgelules

Announcement of some initial results of making and investigating some particularizes of aspirin microfollicle. Percentage of asprin between theory and reality has remarkable change (+16.57 to -1.37). In generally, the microcapsules sample have low rate of Asp/EC, the aspirin microencapsulated rate is high and vice versa. Parameters of asparin percentage, rate of Asp/EC influence on asparin microencapsulated rate. Asparin capsule with EC box can be made with relatively high microencapsulated rate productivity. Aspirin capsule can last liberation of pharmaceutical material and give long-lasting effect in systems
