PROBLEM TO BE SOLVED: To eject a fixed continuous amount of estrogen in a vaginal medicine ejector containing estrogen in a polymer matrix, by allowing the polymer matrix to contain a fatty acid ester including a specified number of carbon atoms. SOLUTION: In a vaginal medicine ejector containing an activator in a polymer matrix, the polymer matrix contains at least one kind of fatty acid ester. Here, the fatty acid ester is formed of a 2-20C fatty acid, particularly a long chain fatty acid, for example caproic acid, lauric acid, myristic acid, oleic acid, linolic acid, adipic acid and lanolin acid. Particularly preferable one is an ester formed of mirystic acid. Also, an alcohol used for forming the has a 2-20 carbon atoms, particularly a 2-4 carbon atoms, for example propanol, particulary isopropanol. |
