Topic:Anti-inflammatory
Anti-inflammatory agents are substances used to reduce inflammation in horses, often employed in the management of various equine conditions. These agents can be categorized into non-steroidal anti-inflammatory drugs (NSAIDs) and corticosteroids, among others. NSAIDs, such as phenylbutazone and flunixin meglumine, work by inhibiting cyclooxygenase enzymes, which play a role in the inflammatory process. Corticosteroids, like dexamethasone, modulate the immune response and reduce inflammation through their effects on gene expression. The use of anti-inflammatory agents is common in equine veterinary practice to alleviate pain and improve the quality of life in horses suffering from musculoskeletal disorders, colic, and other inflammatory conditions. This page compiles peer-reviewed research studies and scholarly articles that explore the pharmacology, efficacy, and safety of anti-inflammatory agents in equine medicine.
Prevention of endotoxin-induced arterial hypoxaemia and lactic acidosis with flunixin meglumine in the conscious pony. Bacterial endotoxin injected intravenously into conscious ponies produced alterations in cardiopulmonary and gastrointestinal function. Specifically, tachypnoea, dyspnoea, hypoxaemia, colic, lactic acidosis and diarrhoea resulted from administration of 10 micrograms/kg Escherichia coli endotoxin. Pretreatment of the ponies with a potent prostaglandin synthetase inhibitor, flunixin meglumine, prevented these ill effects of endotoxin.
Therapeutic effect of phenylbutazone on experimental acute Escherichia coli endotoxemia in ponies. Phenylbutazone (PBZ), a classic anti-inflammatory and prostaglandin-synthesis inhibitor drug, was used to determine the role of prostaglandins and other mediators on the development and perpetuation of the response to intraperitoneal Escherichia coli endotoxin administration. The PBZ (15 mg/kg of body weight) was administered IV 30 minutes after endotoxin administration and was repeated later at 6 and 12 hours at a dose of 10 mg/kg. A variety of evaluation measurements (hematologic, blood glucose, pyruvate, lactate and fibrinogen, serum beta-glucuronidase, prothrombin time, blood gases, hepati...
Thermography in the diagnosis of inflammatory processes in the horse. To evaluate the use of thermography in equine medicine, a three-phase study was conducted. In the first phase, six horses were examined thermographically, before and after exercise, to determine a normal thermal pattern. In the second phase, nine horses with acute and chronic inflammatory processes were examined thermographically. In the third phase, thermography was used to evaluate the effectiveness of anti-inflammatory drugs on chemically induced inflammatory reactions. All normal horses tested had similar infrared emission patterns. There was a high degree of symmetry between right and lef...
A gas chromatographic screening procedure for the detection of non-steroidal anti-inflammatory drugs in horse urine. A gas chromatographic screening procedure for the non-steroidal anti-inflammatory group of drugs is described. The method invovles on-column methylation of the carboxylic acid group using trimethylanilinium hydroxide as the methylating reagent. Fifteen such drugs were studied. Eight of these were detected in urine collected from horses that had received these compounds orally and for these drugs, rates of urinary excretion are recorded. Seven other members of this group of drugs were shown to be detectable by this procedure but in these cases the drug was added to urine and not administered to...
The excretion of ibuprofen by the horse – a preliminary report. The anti-inflammatory drug Ibuprofen [(+/-)-2-(p-isobutylphenyl) propionic acid] was estimated in the blood and urine of a horse using gas-liquid chromatography of the silylated derivative. Levels of the drug in the two body fluids were measured over a period of about 24 hours after administering a 12 gm dose of Ibuprofen. Plasma peak levels were observed within 30 to 60 min, and the drug was no longer detectable in the plasma by 8 hr. Urinary peak levels were observed 200 to 300 min after dosing, and the drug was no longer detectable in the urine by about 28 hr. It was observed that only 2% t...
