用于施加到粘膜的包含甲基纤维素的组合物
摘要：
一种被设计成用于施加到粘膜的组合物包含张力调节剂、甲基纤维素和液体稀释剂，其中所述甲基纤维素具有由1-4个键连接的脱水葡萄糖单元，其中脱水葡萄糖单元的羟基被甲基取代，使得s23/s26是0.36或更小，其中s23是所述脱水葡萄糖单元的仅2和3位的两个羟基被甲基取代的脱水葡萄糖单元的摩尔分数，并且其中s26是所述脱水葡萄糖单元的仅2和6位的两个羟基被甲基取代的脱水葡萄糖单元的摩尔分数。
摘要（英）：

A composition designed for application to a mucosa comprises a tonicity-adjusting agent, a methylcellulose, and a liquid diluent, wherein the methylcellulose has anhydroglucose units joined by 1-4 linkages wherein hydroxy groups of anhydroglucose units are substituted with methyl groups such that s23/s26 is 0.36 or less, wherein s23 is the molar fraction of anhydroglucose units wherein only the two hydroxy groups in the 2- and 3-positions of the anhydroglucose unit are substituted with methyl groups and wherein s26 is the molar fraction of anhydroglucose units wherein only the two hydroxy groups in the 2- and 6-positions of the anhydroglucose unit are substituted with methyl groups.
