Description

组合胶囊
技术领域
本实用新型涉及一种组合胶囊,尤其是涉及具有一个囊帽和两个囊体的胶囊。本实用新型属于制药领域。
背景技术
胶囊制剂是指药物装于空胶囊中制成的一种制剂。胶囊制剂能够掩盖药物不适的苦味及臭味,使其整洁、美观、容易吞服。胶囊制剂制备时内容物可不加粘合剂、不需施加压力,在胃肠道中崩解快,所以有效地提高了药物的生物利用度。同时,胶囊制剂能够提高药物稳定性,如对光敏感的药物、遇湿热不稳定的药物,可装入不透光胶囊中,防护药物不受湿气和空气中氧、光线的作用,从而提高其稳定性。
实用新型内容
胶囊制剂作为一种常用的制剂,在目前制药中有广泛的应用。目前的胶囊制剂中的胶囊由一个囊帽和一个囊体构成,囊体中充填药物,囊帽附于囊体外,封堵囊体开口端,形成一个与外界隔离的腔。但是这种胶囊中充填的必须是单一的药物和与之相配的辅料,或者充填物理或化学上可混合存在的药物有效成分和辅料。然而临床实践中,同时服用几种药物是一种常见现象,例如对于并发症患者,或者单一药物不能有效控制的疾病如糖尿病等。为了减少患者服药次数和服药数量,提高患者依从性,复方制剂的开发已经成为药品研发的一个有效途径。然而,并不是所有药物都可以制成复方制剂,对于某些有物理或化学反应的药物有效成分或药物辅料,则不能简单的充填入现有胶囊中,例如药物成分之间存在吸湿性、物理化学反映或酸碱反应。
针对上述现有技术中存在的技术问题,本实用新型提供一种简单、易于实用的组合胶囊,该组合胶囊由囊帽1、内囊体2和外囊体3构成,囊帽1、内囊体2和外囊体3为U型结构,各自具有开口端和封闭端。囊帽1开口端与内囊体2开口端对向,内囊体2开口端的囊体壁位于囊帽1开口端内,外囊体3开口端与内囊体2开口端同向,外囊体3开口端的囊体壁夹于囊帽1开口端的囊体壁和内囊体2开口端的囊体壁之间。外囊体3通过外囊体3的囊体壁与囊帽1开口端的囊体壁和内囊体2开口端的囊体壁之间的摩擦力与囊帽1和内囊体2联接在一起,形成组合胶囊。
本实用新型提供的一个实施例中,组合胶囊内囊体2开口端的囊体壁向内凹陷形成凹陷4,囊帽1的囊体壁有与凹陷4相对应的凹陷5,凹陷5的头部插入到凹陷4中。当凹陷5的头部插入到凹陷4中,囊帽1与内囊体2扣合在一起,有助于防止囊帽1与内囊体2的脱离。囊帽1开口端的囊体壁还可以有凹陷6,凹陷6的高度小于凹陷5,凹陷6的高度为囊帽1囊体壁到内囊体2囊体壁的距离。
作为一种变形,上述凹陷可以设置成对应的突起,当囊帽1与内囊体2相对应的突起相扣时,有助于囊帽1与内囊体2的结合。通常情况下,这种突起可以有无数对,优选有对应的突起1-8对,更加优选2对。
在本实用新型中,囊帽1、内囊体2和外囊体3可以由胃溶型材料按照硬胶囊的制备方法制成。胃溶型材料选自明胶、动物胶或其它蛋白质成分中的一种或几种。
在本实用新型中,囊帽1和内囊体2可以由肠溶型材料按照硬胶囊的制备方法制成。肠溶型材料选自虫胶、醋酸纤维素酞酸酯、丙烯酸树脂类(如Eudragit L和S型等)、聚醋酸乙烯苯二甲酸酯、邻苯二甲酸羟丙甲纤维素酯、琥珀酸醋酸羟丙甲基纤维素、以及增塑剂(如邻苯二甲酸二乙酯、聚乙二醇、丙二醇、甘油三乙酸酯、邻苯二甲酸二甲酯、癸二酸二丁酯、柠檬酸三乙酯、柠檬酸三丁酯、乙酰基柠檬酸三乙酯、蓖麻油和各种百分比的乙酰化单酸甘油酯、甘油、苯二甲酸二甲酯、苯二甲酸二乙酯、苯二甲酸二丁酯、枸橼酸三乙酯、枸橼酸三丁酯、乙酰基枸橼酸三丁酯、乙酰基枸橼酸三丁酯等)与致孔剂(如PEG类、PVP、蔗糖、盐类)等一种或几种。当囊帽1和内囊体2由肠溶型材料制成时,外囊体3可以由胃溶型材料制成,也可以由肠溶型材料制成,其中胃溶型材料或肠溶型材料参选上述物质。
与传统的胶囊制剂相比,本实用新型提供的复合胶囊的优点在于:①改变传统胶囊的结构,具有两个独立的空腔,可分别充填药物有效成分;②外囊体3开口端的囊体壁夹于囊帽1开口端的囊体壁和内囊体2开口端的囊体壁之间,使胶囊结构紧凑、不易脱离,减少了制剂过程中的胶囊插劈现象,提高胶囊制剂的合成率;③突起或凹陷增加囊帽1和囊体2的紧密结构,使之不易剥离;④囊帽和囊体的材质有助于控制药物释放的部位,从而人为调控药物释放和血药浓度。

五、具体实施方式
实施例1胃肠组合胶囊用途
囊帽1和内囊体2:应用明胶、二氧化钛、着色剂为材料,热融后在特定模具中倒模干燥而成。
外囊体3:应用明胶为主要材料制备普通胶囊,并制备肠溶包衣液进行包衣,具体包衣液组方如下:
丙烯酸树脂II号和丙烯酸树酯III号各2份,蓖麻油2g,邻苯二甲酸二乙酯2g,吐温802g,95%乙醇加至100ml。
生产工艺:将普通胶囊在模具上成模后再蘸一次肠溶包衣液,进行干燥、脱模、切口、套合、即成外囊体3。
得到上述囊帽1和内囊体2后,机械灌装药物,闭合囊帽1和内囊体2,突起5的头部插入到突起4中。外囊体3灌装药物后,外囊体3开口端的囊体壁插入到囊帽1开口端的囊体壁和内囊体2开口端的囊体壁之间,即可形成胃肠复合型胶囊。
