Enrofloxacin (Baytril): Cartilage & Feline Blindness Triage
Clinical Classification & Indications
- Drug Class: Fluoroquinolone Antibacterial
- Approved Uses: Treatment of complex, multi-drug resistant bacterial infections including deep pyodermas, severe pyelonephritis, prostatitis, and Gram-negative sepsis.
Mechanism of Action (Pharmacodynamics)
Inhibits bacterial DNA gyrase (topoisomerase II) and topoisomerase IV, preventing bacterial DNA supercoiling, transcription, and replication, culminating in rapid bactericidal action.
Adverse Reactions & Side Effect Profile
Common / Expected Side Effects
Vomiting, diarrhea, anorexia, mild elevation of hepatic transaminases.
Emergency Red Flag Reactions
In cats: sudden fixed/dilated pupils, bumping into walls, total acute blindness (photoreceptor retinal degeneration). In growing dogs: acute lameness and joint effusion.
Clinical Contraindications & Interactions
- Do Not Use In: Rapidly growing dogs (causes articular cartilage arthropathy in puppies under 8-12 months, or under 18 months in giant breeds). Extreme caution in cats (strict dose cap of 5 mg/kg/day).
Strict Rule S1 Veterinary Prescription Directive
VETERINARY DIRECTIVE: NEVER exceed recommended manufacturer doses in felines. Felines have a defective retinal ABCG2 transporter that causes enrofloxacin to accumulate in the retina, where light exposure generates catastrophic reactive oxygen species that destroy photoreceptors. Never administer human pharmaceutical products or adjust dosages without direct examination and bloodwork by a licensed Doctor of Veterinary Medicine (DVM).
