緑内障点眼容器の使用感に関するアンケート調査分析

A questionnaire survey on handling the containers of ophthalmic solution for glaucoma

要約　目的：市販の緑内障点眼薬の容器の使用感についての報告。対象と方法：2008年の3か月間に受診した緑内障で加療中の患者152例を対象にアンケート調査をした。5種類の製剤につき，キャップの大きさと開けやすさ，容器の硬さと持ちやすさ，液もれの程度，1回の点眼液量，残液量の確認の7項目および使いやすい順位を調べた。結果：使いやすさの順位は，デタントール^®，ミケラン^®，チモプトール^®，キサラタン^®，エイゾプト^®の順であり，デタントール^®は容器把持の面で評価され，エイゾプト^®は容器本体が硬すぎることが不評であった。結論：患者が使用する緑内障点眼薬の容器の使用感については，点眼時の操作性と点眼液の滴下に関する項目が重要であり，これを考慮した容器の採用が望まれる。

Abstract.　Purpose：To report the outcome of survey regarding handling the commercially available plastic containers of ophthalmic solution for glaucoma. Cases and Method：A questionnaire survey was made on 152 outpatients during 3 months of 2008. They were being treated by either of 5 medications for glaucoma and were asked the ranking of their favorite containers and to state the impression regarding 7 items：size of cap of container,ease in opening and closing the cap,easiness of holding the container,rigidity of container,extent of falling in drops out of container,dripping how many drops at a time,and checking the amount of solution in the container. Results：Ease of handling ranked as follows in the decreasing order：Detantol^®,Mikelan^®,Timoptol^®,Xalatan^® and Azopt^®. Detantol^® was favored as the container was easy to hold. Azopt^® was unpopular as the container was too rigid. Conclusion：The current survey has shown that easiness of handling of containers and accuracy of dripping are major factors for designing plastic containers of ophthalmic solution for glaucoma.
