猫的特拉佐会引起轻度镇静,但缺乏肌肉放松和缓解疼痛. 这项研究发现对生命体征的影响很小,心脏功能没有变化,这表明特拉佐对猫使用是安全的.
科学领域:
- 兽医药物学 兽医药物学
- 小动物医学 小动物医学
背景情况:
- 特拉佐在兽医中越来越多地用于改变行为.
- 它对猫的生理和心声学参数的影响需要彻底调查.
研究的目的:
- 评估口服特拉佐对健康猫的镇静,生理变量和心声谱测量的影响.
- 为了确定特拉佐在猫类动物中的剂量依赖性作用和安全性概况.
主要方法:
- 一个随机的,盲目的,交叉研究,涉及八只健康的猫.
- 服用安慰剂或口服特拉佐 (50mg,75mg,100mg) 随着一周的洗期.
- 对镇静,肌肉松,止痛,生理 (SBP,PR,RR) 和心声学变量的评估.
主要成果:
- 特拉佐显著增加了镇静得分,但对肌肉放松或止痛无影响.
- 在最高剂量 (100mg) 时,观察到系统血压 (SBP) 的轻微暂时降低.
- 没有观察到脉冲率 (PR) 或心声学变量的显著变化;呼吸率 (RR) 降低.
结论:
- 在经过测试的剂量中,口服特拉佐会在猫中诱导轻度镇静作用.
- 它表现出良好的安全性,对心血管和呼吸系统的影响最小.
- 特拉佐不提供肌肉放松或镇痛在猫和没有不良心声图效应.
