Description
技术领域
本发明属于医药制剂技术领域,涉及一种兽药,具体地说是一种犬用复方氨基酸肠溶胶囊及其制备方法。
背景技术
现在越来越多的家庭选择驯养犬类宠物,但是有的犬体弱多病,一般情况下,常表现出食欲下降、采食量减少、身体虚弱等症状,出现上述症状后,犬体内的营养物质会随着时间的延长而大量流失,如果上述症状得不到及时改善,就会导致犬生长缓慢甚至死亡。
目前用于增强犬体能的补充液主要为葡萄糖、氯化钠注射液,注射液主要起补充水分和能量,以及调节机体电解质的平衡作用,但无法改善犬体营养状况和补充犬体所需氨基酸。
氨基酸是含有氨基和羧基的一类有机化合物的通称,是生物功能大分子蛋白质的基本组成单位,也是构成动物营养所需蛋白质的基本物质。而如果氨基酸类药物在胃内崩解,对犬的副作用较大,尤其对体弱多病的犬,容易对其胃部产生刺激,进而引发不良反应。
氨基酸的吸收通过小肠黏膜细胞,是由主动运转系统进行,分别转运中性、酸性和碱性氨基酸。
因此,如果能够发明一种在胃内不崩解的氨基酸营养药物,减少对犬胃部刺激,将会极大地改变上述现状。
发明内容
本发明的目的,是要提供一种犬用复方氨基酸肠溶胶囊,其在为犬提供营养的同时,能够避免对犬的胃部产生刺激;
本发明的另外一个目的,是要提供上述一种犬用复方氨基酸肠溶胶囊的制备方法。
本发明为实现上述目的,所采用的技术方案如下:
一种犬用复方氨基酸肠溶胶囊,以250份重量份数计,其制备原料包括:盐酸赖氨酸5~7份、甲硫氨酸1~4份、色氨酸0.5~2份、亮氨酸6~9份、异亮氨酸2~5份、缬氨酸1~4份、苯丙氨酸4~7份、盐酸组氨酸3~6份、盐酸精氨酸4~7份、苏氨酸2~5份、润滑剂2~5份、余量为稀释剂;
所述润滑剂是硬脂酸镁、滑石粉中的任意一种或两种以任意比混合;
所述稀释剂是淀粉、微晶纤维素中的一种或两种以任意比混合。
作为限定,以250份重量份数计,其制备原料包括:盐酸赖氨酸6.66份、甲硫氨酸2.12份、色氨酸0.78份、亮氨酸7.58份、异亮氨酸3.40份、缬氨酸2.72份、苯丙氨酸5.66份、盐酸组氨酸4.92份、盐酸精氨酸5.78份、苏氨酸3.94份、润滑剂4.00份和稀释剂202.44份。
本发明还公开了上述一种犬用复方氨基酸肠溶胶囊的一种制备方法,包括依次进行的以下步骤:
S1、称取各原料,然后将各原料分别过筛,再将盐酸赖氨酸、甲硫氨酸、色氨酸、亮氨酸、异亮氨酸、缬氨酸、苯丙氨酸、盐酸组氨酸、盐酸精氨酸、苏氨酸和稀释剂混合均匀,得物料A;
S2、将物料A通过湿法制粒,然后烘干,制得干颗粒B;
S3、将干颗粒B整粒,然后加入润滑剂混合均匀,灌装入肠溶胶囊壳中,即得所述一种犬用复方氨基酸肠溶胶囊。
作为限定,所述步骤S1中将各原料分别过筛时,将盐酸赖氨酸、甲硫氨酸、色氨酸、亮氨酸、异亮氨酸、缬氨酸、苯丙氨酸、盐酸组氨酸、盐酸精氨酸、苏氨酸分别过100目筛,将稀释剂、润滑剂分别过80目筛。
作为第二种限定,所述步骤S2按照以下步骤顺序进行:

实际操作中,润滑剂为硬脂酸镁、滑石粉中的一种或两种以任意比混合皆可,稀释剂为淀粉、微晶纤维素中的一种或两种以任意比混合皆可,实施例1~6只是给出了具有代表性的例子。
实施例7一种犬用复方氨基酸肠溶胶囊的制备方法
本实施例用于制备实施例1~6,制备方法按照以下步骤顺序进行:
S1、混料
本步骤按照以下步骤顺序进行,
S11、按照实施例1~6中所示的各原料重量分别称取各原料;
S12、将盐酸赖氨酸、甲硫氨酸、色氨酸、亮氨酸、异亮氨酸、缬氨酸、苯丙氨酸、盐酸组氨酸、盐酸精氨酸、苏氨酸分别过100目筛,将稀释剂、润滑剂分别过80目筛;
S13、将盐酸赖氨酸、甲硫氨酸、色氨酸、亮氨酸、异亮氨酸、缬氨酸、苯丙氨酸、盐酸组氨酸、盐酸精氨酸、苏氨酸和稀释剂混合均匀,得物料A;
S2、制粒
本步骤按照以下步骤顺序进行,
S21、将物料A用质量浓度为2%的羟丙甲纤维素溶液湿法制粒,过24目筛制得湿颗粒A1;
其中,羟丙甲纤维素溶液的溶剂是质量浓度为50%的乙醇溶液;
S22、将湿颗粒A1在115℃条件下烘干,制得干颗粒B;
S3、灌装
将干颗粒B以20目筛整粒,加入润滑剂,混合均匀,灌装入肠溶胶囊壳中,制成1000000粒,即得犬用复方氨基酸肠溶胶囊。
本实施例采用的肠溶胶囊壳为市售产品。
实施例8 犬用复方氨基酸肠溶胶囊的质量检测
参照产品质量标准规定的方法对采用实施例1~6的配方,按照实施例7提供的制备方法制成的犬用复方氨基酸肠溶胶囊的质量进行检验,检测结果如表2所示。
表2 实施例1~6的犬用复方氨基酸肠溶胶囊质量检测结果
由上表可知,按照实施例1~6的配方制备的犬用复方氨基酸肠溶胶囊各项检测结果均符合产品质量标准规定,氨基酸含量能够满足犬对氨基酸的营养需求。崩解时限检测结果表明,采用实施例1~6的配方,按照实施例7的制备方法制得的肠溶胶囊均不在胃部崩解吸收,而在肠内崩解吸收,由此可见,本发明的犬用复方氨基酸肠溶胶囊,在犬肠内崩解吸收,减少了对犬胃部产生刺激而引发的不良反应,降低了药物对犬食欲产生的不良影响。
实施例9犬用复方氨基酸肠溶胶囊的稳定性测试
对采用实施例1~6的配方,按照实施例7提供的制备方法制成的犬用复方氨基酸肠溶胶囊进行稳定性考察,具体实施方案如下:
将上述犬用复方氨基酸肠溶胶囊,在温度40℃±2℃、相对湿度75%±5%的条件下放置6个月,按产品质量标准进行检验,检验结果如下表3所示。
表3 实施例1~6的犬用复方氨基酸肠溶胶囊稳定性测试结果
由上表可知,经6个月的加速试验,采用实施例1~6提供的配方,按照实施例7提供的制备方法制备的犬用复方氨基酸肠溶胶囊各项检测数据无显著变化,表明上述犬用复方氨基酸肠溶胶囊产品稳定性良好。
实施例9 犬用复方氨基酸肠溶胶囊有效性试验
选取经临床诊断为蛋白质缺乏症的比格犬180只,随机分成12组,分别为对照组1~6和试验组1~6,病犬表现为消瘦、被毛粗硬无光泽、体重减轻、食欲不振及精神萎靡。
其中对照组1~6病犬口服犬用复方氨基酸胃溶胶囊(犬用复方氨基酸胃溶胶囊的配方分别与实施例1~6一一对应相似、制备步骤与实施例7相似,不同之处仅在于:所用胶囊壳由肠溶胶囊壳更换为胃溶胶囊壳),5粒/次/日,连用7日;试验组1~6病犬分别一一对应口服按照实施例7的方法,采用实施例1~6的配方制备的犬用复方氨基酸肠溶胶囊,5粒/次/日,连用7日。统计并记录病犬的体重、进食量、不良反应、被毛状况及精神状态,具体用法用量及试验结果汇总如下表4所示。
表4 犬用复方氨基酸肠溶胶囊有效性试验
本实施例中的胃溶胶囊壳为市售产品。
由上表可知,经过7日的治疗观察,对照组1~6病犬进食量均有增加,体重均有增长,被毛状况及精神状态未见改善,均有犬出现呕吐反应,而试验组1~8的病犬进食量均有增加,体重均有增长,进食量增加和体重增长幅度均优于对照组,被毛及精神状态也均有改善,未见呕吐反应。试验结果表明,本发明提供的一种犬用复方氨基酸肠溶胶囊能够补充犬体对氨基酸的需求,降低药物对患犬食欲产生的不良影响。
