Description

氟康唑滴眼液
所属技术领域
本发明涉及一种药物有效成分——氟康唑——首次制成滴眼液,应用于眼科真菌感染的治疗。
背景技术
近一二十年来,真菌感染性眼病逐渐增多,尤其是临床上广泛应用抗生素、皮质激素以及免疫制剂,更增加了真菌性眼病的上升趋势。目前国内还没有局部应用的抗真菌眼药,临床上一般采用注射剂或口服制剂进行治疗。氟康唑用作滴眼液目前还未见有研究和生产的报道。
发明内容
抗真菌感染药物氟康唑首次被制成滴眼液,不仅克服给药量大,口服药物难以通过血眼屏障的不足,而且使用量少,提高药物有效成分的生物利用度,增加疗效和用药安全性。
本发明的技术方案是:氟康唑药物成分与丙二醇搅拌混合,使之充分分散均匀,加注射用水溶解后与苯扎氯铵溶液混合,制成滴眼液,用于眼科真菌感染的治疗,使用量少且作用持久。其具体特征如下:
氟康唑滴眼液单方制剂,其正式名:氟康唑滴眼液;化学名:2-(2.4-二氟苯基)-1.3-双(1H-1.2.4-三氮唑基)-2-丙醇滴眼液;英文名:Fluconazole EyeDrops;汉语拼音:Fukangzuo Diyanye;商品名:普芬。药物与主要辅料成分及其按下列比例组成的应用于眼科疾患的制剂:其中含氟康唑为0.1-2.5%(w/w);含丙二醇为0-10.0%(w/w);含苯扎氯铵为0-0.1%(w/w)。氟康唑药物有效成分,与丙二醇充分混合,使之充分分散均匀;加适量注射用水研磨溶解;苯扎氯铵加适量注射用水溶解:二者混合,搅拌均匀,补水至全量;热压灭菌;过滤;分装;即得。上述制备工艺中,其核心技术是:(1)氟康唑药物成分与丙二醇充分混合,研磨使之分散均匀;(2)加注射用水溶解后与苯扎氯铵液混合均匀;(3)补全量后加热(温度115℃,时间30分钟)灭菌。
本发明的积极效果:氟康唑滴眼液的研制与开发有以下优点:(1)、比口服给药成本低,口服每日给药量为300-600mg,而氟康唑滴眼液主药含量为0.5%,每日使用量约1.50-2.25ml,药物成分每日使用量为7.5-12.5mg。(2)、氟康唑滴眼液直接作用于患处,能充分有效地发挥作用,可避免口服药物治疗所带来的口服药物治疗所带来的胃肠道刺激和其他副作用。(3)、相对于其它眼用制剂,氟康唑眼用制剂具有无可比拟的优点:不易被泪液稀释,在眼内停留时间长,有利于主药的充分吸收和利用而且使用方便。本产品的开发成功,不仅可填补国内眼科用药的一项空白,还可带来很好的社会效益和经济效益。(4)、我们企业是国内专业的眼科用药生产厂家,30多年来一直致力于眼药的生产、研制、开发,积极参加社会公益事业,眼科用药占总产值的90%以上。
