Study on Preparation of Nateglinide Tablets

To study and evaluate the quality of Nateglinide tablets the formulation is screened. The feasibility of its technics is investigated according to the content changes of Nateglinide in different formulations under high temperarature, high humidity and strong light conditions. A reasonablely designed formulation with feasible technics was selected. Nateglinide tablets made of this formulation and technics measured up to the expected standard. The formulation and technics of Nateglinide tablets are feasible in practice and its quality criteria can effectively control.
