Description

复方甲氧那明的速释一缓释制剂
技术领域
本发明涉及一类含有药物成分为甲氧那明或其盐酸盐、 那可丁、 氨茶碱、 马来酸氯苯那敏, 1 -70% 为速释制剂, 99-30%为缓释制剂, 且可以 8至 24小时持续释放的复方速释一缓释制剂。
背景技术
复方甲氧那明为平喘药, 用于支气管哮喘和喘息性支气管炎。盐酸甲氧那明可抑制支气管痉挛, 缓 解哮喘发作时的咳嗽。 那可丁为外周性止咳药, 可抑制咳嗽。氨茶碱亦可抑制支气管痉挛, 还可抑制支 气管粘膜肿胀, 缓解哮喘发作时的咳嗽, 使痰易咳出。 马来酸氯苯那敏具抗组胺作用。 本品的配伍不仅 可以减轻咽喉及支气管炎症等引起的咳嗽, 而且可缓解哮喘发作时的咳嗽, 有利于排痰。 目前复方甲氧 那明产品的服用方法为口服一次 2粒, 一日 3次。
中国专利 200410065967.4公布了含有甲氧那明、 那可丁、 氨茶碱、 马来酸氯苯那敏的口服固体制 剂的制备方法,使用该方法制得的复方甲氧那明产品不具备缓释释放的功效。按照现有的市售药品服用 方法, 不仅服用剂量较大, 而且服用次数多, 不利于保障病患者按时吃药。 长效缓释制剂能维持长时 间的药效, 可以弥补速释制剂的不足, 但是单纯的长效缓释制剂常有起效慢的缺点。而病患对平喘止咳 药有迅速起效缓解症状的需求。
基于现有制剂产品的缺点以及平喘止咳药既要起效快,又要维持长效的需求,本发明提供了一种将 有效成分 1-70%为速释制剂, 99-30%为缓释制剂, 缓释释放达 8至 24小时的复方制剂。 本发明可实现 药物迅速发挥药效, 且能维持药效达 8至 24小时。
