Abstract:Objective: To study the conditions and parameters of roller compaction of Banlangen effervsce tablet. Method: The experimentation adopts L9 (34) orthogonal experiment to study the conditions and parameters of roller compaction of Banlangen effervsce tablet; studied factors that included roller pressure, roller speed and moisture content of power,which influence the result of granule yield and granule friability. Result: The optimal technique is: roller pressure at 1.5 MPa; roller speed at 15 Hz; moisture content of power at 1.5%. Conclusion: The study of roller compaction technique of Banlangen effervsce tablets provides some technicial consults of its research and production.
