Objective: To prepare Xiaojin sustained release pellets and investigate release in vitro of Xiaojin sustained release pellets with different coating conditions by ferulic acid was determined as index. Method: Single factor test was applied to optimize the coating formulations. Result: A 10 h-sustained release curve was satisfactorily obtained by using EC as coating material and lactose 12% as porogenic agent in the optimized coating formulation with a 10% of coating weight gained. Conclusion: Coating material
coating weight gained and the amount of porogenic agent are the key factors that can significantly affect the drug release in vitro .
