In the ever-evolving field of veterinary medicine, effective antimicrobial agents are indispensable for maintaining animal health and welfare, and consequently, for ensuring food safety and security. Enrofloxacin Hydrochloride (CAS 112732-17-9) has established itself as a pivotal synthetic antibiotic, widely employed by veterinarians and pharmaceutical manufacturers worldwide. This fluoroquinolone offers a potent solution against a broad spectrum of bacterial pathogens, making it a cornerstone in the treatment and prevention of numerous animal diseases. For pharmaceutical formulators, understanding its applications and sourcing from reliable manufacturers is key to developing successful veterinary drug products.

Broad-Spectrum Efficacy Against Bacterial Pathogens
The primary strength of Enrofloxacin Hydrochloride lies in its broad-spectrum activity. It is highly effective against a wide range of Gram-negative bacteria, including common culprits like *E. coli*, *Pasteurella*, *Salmonella*, and *Pseudomonas*. Furthermore, it demonstrates significant efficacy against Gram-positive bacteria such as *Staphylococcus* and *Streptococcus*, as well as against *Mycoplasma* species. This comprehensive coverage makes it a versatile choice for treating diverse infections encountered in veterinary practice.

Key Applications in Animal Health
Enrofloxacin Hydrochloride is extensively used across various animal species for treating specific bacterial infections. Its applications include:

  • Livestock and Poultry: Treatment of respiratory infections (like pneumonia and bronchitis), gastrointestinal infections (such as colibacillosis and salmonellosis), urinary tract infections, and skin/wound infections in cattle, pigs, sheep, goats, chickens, turkeys, and ducks.
  • Aquaculture: Combating bacterial diseases in fish and shrimp farms, often targeting *Aeromonas* and *Vibrio* species.
  • Companion Animals: Managing bacterial infections in dogs and cats, including otitis externa/interna, skin infections, and urinary tract infections.

Beyond therapeutic treatment, Enrofloxacin Hydrochloride is also utilized prophylactically in intensive farming operations to prevent disease outbreaks, particularly in poultry and swine. This strategic use, however, is subject to regulatory guidelines and recommendations to mitigate the development of antibiotic resistance.

Mechanism and Pharmacological Advantages
Enrofloxacin Hydrochloride functions by inhibiting two essential bacterial enzymes: DNA gyrase and topoisomerase IV. These enzymes are critical for DNA replication, transcription, repair, and recombination. By blocking their activity, Enrofloxacin disrupts bacterial DNA processes, leading to rapid bacterial cell death. Pharmacologically, its advantages include rapid absorption after oral administration, high bioavailability, and excellent penetration into tissues and organs, which is crucial for treating deep-seated or systemic infections.

Sourcing High-Quality Enrofloxacin Hydrochloride
For pharmaceutical companies aiming to manufacture veterinary drugs, sourcing high-purity Enrofloxacin Hydrochloride from a reputable manufacturer is crucial. Suppliers like NINGBO INNO PHARMCHEM CO.,LTD. offer this API with guaranteed quality, competitive pricing, and reliable supply chains. When evaluating a supplier, consider factors such as assay percentage, impurity profiles, and adherence to international pharmacopoeia standards. Ensuring a stable supply of this API is vital for consistent product manufacturing and market availability. To buy Enrofloxacin Hydrochloride, formulators should look for partners who can provide not just the product, but also comprehensive technical support and efficient logistics.

Conclusion
Enrofloxacin Hydrochloride is an indispensable tool in modern veterinary medicine, offering a potent and versatile solution for combating bacterial infections across a wide range of animal species. Its efficacy, coupled with favorable pharmacokinetic properties, makes it a highly sought-after API. Pharmaceutical manufacturers looking to develop or produce effective veterinary treatments should prioritize partnering with reliable global suppliers who can guarantee quality and consistent supply of this critical compound.
