Abstract
本发明公开一类含有药物成分为甲氧那明或其盐酸盐、那可丁、氨茶碱、马来酸氯苯那敏的复方速释-缓释制剂。其速释部分含有1~70%的有效成分,缓释部分含有30~99%的有效成分,且可以8至24小时持续释放。所述复方速释-缓释制剂包括速释-缓释片剂、速释-缓释胶囊剂、速释-缓释混悬剂。
Description
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-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。
