[Study on the preparation of rapid-dissoluted EGb droppills].

OBJECTIVE: To study the formulation and technique of preparation of rapid-dissoluted EGb (Extract of Ginkgo biloba) droppills. METHOD: Taking the dissolution percentage of total flavonoids in EGb and weight variation as index, the formulation and technique of EGb droppills were optimized by the orthogonal experiment. RESULT: T50 was 3.62 min and mean weight variation was 2.80%. CONCLUSION: Rapid-dissoluted EGb droppills can increase the dissoluting rate distinctly and reach the purpose of preparation.
