About flunixin meglumine (the active ingredient)
Non-steroidal anti-inflammatory drug (NSAID, nicotinic acid derivative — non-selective).
How it works
NSAIDs reduce prostaglandin production by inhibiting the cyclooxygenase (COX) enzymes [2]. Flunixin is a non-selective COX inhibitor [2].
Key safety points
- Banamine injection is approved only for IV use in cattle — IM injection has left violative residues in meat [3].
- Not for use in dry dairy cows, veal calves, breeding bulls or horses intended for food (Banamine label) [3].
- Pour-on: do not use in animals with liver, kidney or heart disease, gut ulceration or platelet disorders [4].
