Objective To optimize the technical parameters on Qingnao Jiangya Dropping Pills. Methods To investigate the preparation technique and optimal formulation of Qingnao Jiangya Dropping Pills based on the studies of influential factors, optimal formulation was obtained by the orthogonal design. Results The optimum molding parameters were as follows: the ratio between drug and matrix was 1∶2, matrix was PEG 6000, dropping temperature was 75 ℃, the cooling fluid temperature was 10 ℃. Conclusion The optimization of the molding process is simple, high-yield, and the weight deviation and the disintegration time conform to the standard.
