  • 常用中文名:氟苯尼考
  • 常用英文名:Florfenicol
  • CAS号:73231-34-2
  • 分子式:C12H14Cl2FNO4S
  • 分子量:358.213
  • 相关类别: 原料药 解热镇痛药 非甾抗炎药

  • 抗生素类药物,氟苯尼考通过抑制肽酰基转移酶活性而产生广谱抑菌作用,抗菌谱广,包括各种革兰氏阳性、阴性菌和支原体等。敏感菌包括牛、猪的嗜血杆菌、痢疾志贺氏菌、沙门氏菌、大肠杆菌、肺炎球菌、流感杆菌、链球菌、金黄色葡萄球菌、衣原体、钩端螺旋体,立克次氏体等。
    兽用抗生素:氟苯尼考是目前常用的一种兽用抗生素,抗菌谱广,抑菌作用强,最小抑菌浓度(MIC)低,抗菌效果是氯霉素、甲砜霉素的15-20倍,饲料给药后60分钟,组织中药物浓度可达峰值,能迅速控制病情,安全性高、无毒、无残留等特点,无潜在致再生障碍性贫血的隐患,适合规模化大型养殖场使用,主要用于治疗巴斯德氏菌和嗜血杆菌引起的牛呼吸道疾病。对梭杆菌引起的牛腐蹄病有较好疗效。亦用于敏感菌所致的猪、鸡传染病及鱼的细菌性疾病。
    氟苯尼考不易产生耐药性:因为用氟原子取代了甲砜霉素分子结构中的羟基,有效地解决了对氯霉素、甲砜霉素产生耐药性问题。对甲砜霉素、氯霉素、阿莫西林、喹诺酮类耐药的菌株对本品仍然敏感。
    由于氯霉素具有严重的导致再生障碍性贫血和免疫抑制等不良反应,故在食品动物生产中禁止使用。经研究证明:氯霉素化学结构中引起再生障碍性贫血的主要基团是芳香环上的对位硝基。而氟苯尼考则是以CH3SO4取代了NO2基团,使化学结构发生了改变,故用于动物体内不产生再生障碍性贫血的不良反应。因此,在日本、墨西哥和中国的十多个国家被批准使用。氟苯尼考的特点是:抗菌谱广,对沙门氏菌、大肠杆菌、变形杆菌、嗜血杆菌、胸膜肺炎放线杆菌、猪肺炎支原体、猪链球菌、猪巴氏杆菌、支气管败血博氏杆菌、金黄色葡萄球菌等均敏感。该药物易于吸收,在体内分布广泛,为速效、长效型制剂,无潜在致再生障碍性贫血的隐患,安全性较好。此外,价格适中,比其它防治呼吸道疾病的药物如泰妙菌素(支原净)、替米考星、阿奇霉素等都便宜,用药成本易于为用户接受。由于具有这些特点,国产氟苯尼考得到广泛应用,成为当前防治畜禽呼吸道和消化道细菌性感染病的首选药物。
    氟苯尼考不宜与喹诺酮类、青霉素类、头孢菌素类药物联合应用,不宜与氨苄西林、磺胺类、呋喃类药物配伍。  
  • 氟苯尼考通过与细菌核糖体上的50S亚基紧密结合,阻碍肽酰基转移酶的转肽反应,从而抑制肽链的延伸;同时选择性地作用于组成细菌菌体的70S核蛋白体的受体,改变和干扰肽酰转移酶的功能,从而双重干扰细菌蛋白质的合成。抗生素类药物,通过抑制肽酰基转移酶活性而产生广谱抑菌作用,抗菌谱广,包括各种革兰氏阳性、阴性菌
    和支原体等。敏感菌包括牛、猪的嗜血杆菌、痢疾志贺氏菌、沙门氏菌、大肠杆菌、肺炎球菌、流感杆菌、
    链球菌、金黄色葡萄球菌、衣原体、钩端螺旋体,立克次氏体等。
