Applications

1. Veterinary Anti-inflammatory Agent

Flunixin meglumin丨CAS 42461-84-7 is widely administered to livestock and companion animals to manage pain and inflammation resulting from:

● Musculoskeletal disorders (e.g., lameness, arthritis)

● Colic in horses

● Respiratory tract infections

● Mastitis and metritis in cattle

● Post-surgical pain management

It is particularly favored for its rapid onset of action and long-lasting effect (up to 24–36 hours in some species).

2. Antipyretic (Fever-Reducing) Agent

In livestock, flunixin meglumine is effective in reducing fever associated with infections or systemic diseases, especially during outbreaks of viral or bacterial illnesses.

● Often used in conjunction with antimicrobial therapy to improve clinical outcomes.

● Commonly used during shipping fever complex in cattle and equine viral respiratory infections.

3. Endotoxemia and Septic Shock Management

Flunixin meglumine plays a critical role in treating endotoxemia in horses and cattle by:

● Inhibiting the effects of endotoxins released by Gram-negative bacteria

● Reducing inflammation-mediated organ damage

● Supporting circulatory and gastrointestinal function in critical care

Benefits

1. Potent and Fast-Acting

Flunixin meglumine provides rapid relief, with measurable anti-inflammatory and analgesic effects occurring within 2 hours of administration. This is particularly important in acute pain scenarios like colic or trauma.

2. Extended Duration of Action

Its long half-life in animals means that once-daily dosing is often sufficient, improving treatment compliance and minimizing handling stress in animals.

3. Broad Spectrum of Use

Approved for use in multiple species including horses, cattle, swine, and companion animals. Its efficacy across various inflammatory conditions makes it a versatile tool in veterinary practice.

4. Synergistic Use with Other Therapies

Often used alongside antibiotics, rehydration, or supportive therapies to improve the recovery of animals with systemic or infectious illnesses.

5. Regulatory Approval and Safety

Flunixin meglumin丨CAS 42461-84-7 is approved by regulatory bodies like the FDA and EMA for veterinary use, with clearly established withdrawal times for milk and meat in food-producing animals, ensuring safe and responsible use.
