Objective: To select optimal composing of the prescription of ibuprofen solid dispersion tablet by investigating the influence of several disintegrants to disintegrate time limited. Methods: Using the orthogonal design for selecting the best amounts of CMS Na, MCC, the appearance of tablets, dissolution rate, suspensibility and disintegration time were as index. Results: The dissolution of that tablets was fast, could be completely form into suspension, which could screen through the 710 μm mesh. Conclusio...
