Abstract:
Objective:To optimize the formula of amlexanox nasal thermosensitive gel spray and establish the quality control meth-od. Methods:Amlexanox nasal thermosensitive gel spray was prepared by a cold dissolving method, and poloxamer 407 (P407) and poloxamer 188 (P188) were used as the carrier materials. Central composite design-response surface methodology was used to optimize the formula with the amount of P407 and P188 as the influencing factors and the gel temperature and the viscosity before gelling as the indices. The content of amlexanox was determined by HPLC. According to Chinese Pharmacopoeia (2010 edition), the other indices of the preparation such as appearance, pH, viscosity, content, total spray times of each bottle and the content of each spray were deter-mined as well. Results:The optimum ratio of P407 and P188 was 17. 0% and 0. 9%,respectively . The average recovery of amlexanox was 98. 8% and RSD was 1. 7%(n=9). The quality of 3 batches of amlexanox nasal thermosensitive gel spray met the related require-ments. Conclusion:The formula and preparation process of amlexanox nasal thermosensitive gel spray are reasonable and feasible with controllable quality, which is worthy of further research.
