flunixin meglumine 50 mg in 1 mL
INTRAMUSCULAR
PRESCRIPTION
Horse: Flunixin Injection is recommended for the alleviation of inflammation and pain associated with musculoskeletal disorders in the horse. It is also recommended for the alleviation of visceral pain associated with colic in the horse. Cattle: Flunixin Injection is indicated for the control of pyrexia associated with bovine respiratory disease, endotoxemia and acute bovine mastitis. Flunixin Injection is also indicated for the control of inflammation in endotoxemia. Horse: There are no known contraindications to this drug when used as directed. Intra-arterial injection should be avoided. Horses inadvertently injected intra-arterially can show adverse reactions. Signs can be ataxia, incoordination, hyperventilation, hysteria and muscle weakness. Signs are transient and disappear without antidotal medication within a few minutes. Do not use in horses showing hypersensitivity to flunixin meglumine. Cattle: NSAIDs inhibit production of prostaglandins which are important in signaling the initiation of partur
Flunixin Injection (flunixin meglumine injection), 50 mg/mL, is available in 50 mL, 100 mL and 250 mL multi-dose vials. Store between 2° and 30°C (36° and 86°F). Use within 60 days of first puncture. When using a draw-off spike or needle with a bore diameter larger than 16-gauge, discard any product remaining in the vial immediately after use.
Abbreviated New Animal Drug Application
FLUNIXIN- FLUNIXIN MEGLUMINE INJECTION, SOLUTION NORBROOK LABORATORIES LIMITED ---------- FLUNIXIN INJECTION (FLUNIXIN MEGLUMINE INJECTION) 50 MG/ML ONLY FOR INTRAVENOUS USE IN BEEF AND DAIRY CATTLE. NOT FOR USE IN DRY DAIRY COWS AND VEAL CALVES. FOR INTRAVENOUS AND INTRAMUSCULAR USE IN HORSES. CAUTION Federal law restricts this drug to use by or on the order of a licensed veterinarian. DESCRIPTION Each milliliter of Flunixin Injection contains 50 mg flunixin (equivalent to 83 mg flunixin meglumine), 0.1 mg edetate disodium, 2.5 mg sodium formaldehyde sulphoxylate, 4.0 mg diethanolamine, 207.2 mg propylene glycol, 5.0 mg phenol as preservative, hydrochloric acid, water for injection q.s. PHARMACOLOGY Flunixin meglumine is a potent, non-narcotic, non-steroidal, analgesic agent with anti- inflammatory and anti-pyretic activity. It is significantly more potent than pentazocine, meperidine, and codeine as an analgesic in the rat yeast paw test. _Horse:_ Flunixin is four times as potent on a mg-per-mg basis as phenylbutazone as measured by the reduction in lameness and swelling in the horse. Plasma half-life in horse serum is 1.6 hours following a single dose of 1.1 mg/kg. Measurable amounts are detectable in horse plasma at 8 hours post injection. _Cattle:_ Flunixin meglumine is a weak acid (pKa=5.82) which exhibits a high degree of plasma protein binding (approximately 99%) . However, free (unbound) drug appears to readily partition into body tissues (VSS predictions range from 297 to 782 mL/kg. Total body water is approximately equal to 570 mL/kg) . In cattle, elimination occurs primarily through biliary excretion . This may, at least in part, explain the presence of multiple peaks in the blood concentration/time profile following IV administration . In healthy cattle, total body clearance has been reported to range from 90 to 151 mL/kg/hr . These studies also report a large discrepancy between the volume of distribution at steady state (VSS) and the volume of distribution associated with the terminal elimination p Read the complete document
