개요

다노플록사신은 주로 육우의 소 호흡기 질병(BRD) 치료에 사용되는 수의학 전용 주사용 ​플루오로퀴놀론계 항생제​입니다. Mannheimia haemolyticaPasteurella multocida와 같은 주요 호흡기 병원체에 대해 농도 의존적 살균 활성을 나타냅니다.

​임상 요점:​

  • 다른 플루오로퀴놀론계와 마찬가지로 조직 침투력이 뛰어나며, 특히 폐 조직에 대한 침투력이 우수하여 호흡기 감염에 매우 효과적입니다.
  • 분포 용적이 크며 삼출물 및 누출물에 잘 농축됩니다.
  • ​규제 경고:​ 미국 FDA는 식용 동물에 대한 플루오로퀴놀론계 약물의 허가 외 사용(extra-label use)을 엄격히 금지하고 있습니다.

작용 기전

Fluoroquinolones are bactericidal antibiotics that act by inhibiting bacterial DNA replication and transcription.

  • They enter the bacterium and inhibit DNA gyrase (topoisomerase II) and topoisomerase IV.
  • Inhibition of DNA gyrase → prevents DNA supercoiling → halts DNA replication.
  • Inhibition of topoisomerase IV → interferes with the separation of interlinked replicated DNA molecules.
  • This dual action leads to rapid bacterial cell death. The bactericidal activity is concentration-dependent rather than time-dependent.

안전성·주의사항

금기사항

  • Extra-label use in food-producing animals (FDA prohibited)
  • Lactating dairy cattle (where milk is for human consumption)
  • Veal calves
  • Animals with known or suspected CNS disorders (relative contraindication)
  • Known hypersensitivity to ofloxacin or other fluoroquinolones

부작용

  • Hypersensitivity reactions (uncommon)
  • Lameness or arthropathies (especially in young animals/calves)
  • Local tissue reaction at the subcutaneous injection site (may result in trim loss)
  • Mild, transient ocular irritation or stinging upon application (general class effect)
  • Conjunctival hyperemia (rare)

주의

The FDA strictly prohibits extra-label usage of this drug in food animals. Use with caution in animals with known or suspected CNS disorders, as quinolones have rarely caused CNS stimulation. Do not use in lactating dairy cattle or calves to be processed for veal.

약물 상호작용

Theophylline (aminophylline)

Potential increase in serum concentrations of theophylline; increased monitoring of theophylline concentrations is recommended

모니터링

  • Clinical efficacy
  • Injection site reactions
  • Signs of lameness or CNS stimulation
  • Clinical response to therapy (resolution of ocular discharge, inflammation, or ulceration)
  • Culture and sensitivity testing prior to and during prolonged treatment if no improvement

약동학

반감기

고양이Not established for topical routeNot established for topical route

흡수

Rapidly absorbed after subcutaneous injection in cattle with high bioavailability (≈90%). Peak serum levels occur about 2-3 hours after dosing.

분포

High volume of distribution (approximately 2.7 L/kg in cattle); lung levels exceed those in plasma. Penetrates well into exudates and transudates.

대사

In cattle, minimal metabolism occurs. Other species may metabolize greater percentages of the drug into a desmethyl metabolite (desmethyldanofloxacin).

배설

In cattle, elimination is primarily as unchanged drug into the urine. Terminal elimination half-life in cattle ranges from 3-6 hours.

과다투여

Limited information is available for cattle. High dosages (18-60 mg/kg for 3-6 days) in feeder calves can cause arthropathies/lameness (consistent with other fluoroquinolones), CNS stimulation (ataxia, nystagmus, tremors), inappetence, recumbency, depression, and exophthalmos. Some calves receiving 18 mg/kg twice 48 hours apart developed nasal pad erythema.

In adult dogs, 2.4 mg/kg/day PO for 90 days resulted in no observable adverse effects.

보관·안정성

Store at or below 30°C (86°F) and protect from light and freezing. The color of the solution (yellow to amber) does not affect potency. Do not mix with other medications or diluents, as fluoroquinolones are very sensitive to pH changes and chelation with cationic substances (calcium, magnesium, zinc).

보호자 정보
