Description

一种治疗猪的无名高热病的注射液
技术领域
本发明涉及一种注射液,尤其涉及一种治疗猪的无名高热病的注射液。
背景技术
目前,在兽药领域,人们在探求一种长效的复方磺胺间甲氧嘧啶注射液,磺胺间甲氧嘧啶是体内外抗菌作用最强的磺胺药,对大多数革兰氏阳性菌和阴性菌都有较强抑制作用,主要用于其敏感菌所引起的呼吸道、消化道、泌尿道感染及球虫病、猪弓形体病、鸡住白细胞虫病,用于治疗猪的无名高热总有效率为98.09%、痊愈率为96.18%.。本发明提供了一种治疗猪的无名高热病的注射液,在保证疗效的情况下,延长了磺胺药物在体内的停留时间,根据有关资料记载,聚乙烯吡咯烷酮可与磺胺药可逆地结合为大分子复合物,在体内缓慢释放而达到长效作用。
发明内容
本发明的目的在于提供一种治疗猪的无名高热病的注射液,该注射液有效治疗猪的无名高热,延长了磺胺药物在体内的停留时间。
本发明是这样来实现的,其特征是由以下重量配比的原料制成:
磺胺间甲氧嘧啶50~150克、甲氧苄啶20~40克、α-吡咯烷酮400~800克、聚乙烯吡咯烷酮305~50克、余量为水。
本发明的优点是:1、制作简单,有效治疗猪的无名高热;2、延长了磺胺药物在体内的停留时间,能在体内缓慢释放而达到长效作用。
具体实施方式
实施例一
将磺胺间甲氧嘧啶100克、甲氧苄啶20克、α-吡咯烷酮500克、聚乙烯吡咯烷酮30  25克与水混合至1000毫升,将20头大约克夏猪平分成两组,第一组肌肉注射本发明的注射液,第二组肌肉注射市场上具有长效作用的同类产品,皆按每Kg体重20mg计量注射。分别在0.25、0.50、0.75、1.00、2.00、3.00、5.00、9.00、12.00、24.00、36.00、48.00、60.00、72.00、96.00、108.00小时,从前腔静脉采血10ml,经HPLC分析血样的血药浓度及MCPKP软件拟合处理,得出了相关动力学参数。
  参数   第一组   第二组
  Cmax   10.1μg/ml±1.17μg/ml   10.36μg/mL±2.41μg/ml
  AUC   446.98μg/(mL·h)±30.76μg/(mL·h)   248.51μg/(mL·h)±15.21μg/(mL·h)
  t1/2β   18.7h±3.18h   9.88h±3.56h
从数据可知:第一组的AUC、t1/2β值都明显大于第二组。
实施例二:
将磺胺间甲氧嘧啶90克、甲氧苄啶25克、α-吡咯烷酮600克、聚乙烯吡咯烷酮3040克与水混合至1000毫升,将20头大约克夏猪平分成两组,第一组肌肉注射本发明的注射液,第二组肌肉注射市场上具有长效作用的同类产品,皆按每Kg体重20mg计量注射。分别在0.25、0.50、0.75、1.00、2.00、3.00、5.00、9.00、12.00、24.00、36.00、48.00、60.00、72.00、96.00、108.00小时,从前腔静脉采血10ml,经HPLC分析血样的血药浓度及MCPKP软件拟合处理,得出了相关动力学参数。
  参数   第一组   第二组
  Cmax   10.1μg/ml±1.17μg/ml   10.36μg/mL±2.41μg/ml
  AUC   495.89μg/(mL·h)±30.76μg/(mL·h)   245.51μg/(mL·h)±15.21μg/(mL·h)
  t1/2β   19.7h±3.18h   9.45h±3.56h
从数据可知:第一组的AUC、t1/2β值都明显大于第二组。
