Abstract:
Objective: To seek the optimum technology of drying and to solve the problem of powder sticking clump. Methods : On the basis of major drying condition, such as duration of drying, temperature of drying, evaluating different drying technology; On the basis of the quantity of the powder sticking on the wall and the hygroscopicity of one, investigating different excipients how to affect the spray drying. Seeking the optimum kinds and quantity of excipients. Results : The best properties of the granules are from the spray drying process. ?-cyclodextrin and lactose have the effects on solving the powder sticking on the wall. Conclusion : The spray drying process is the optimum one. Adding 3～5 percent of ?-cyclodextrin has an effect on improving the phenomenon of powder sticking on the wall in process of the spray drying.
