The development of reproducible models of acute inflammation in which inflammatory heat is easily quantified and from which inflammatory exudate is readily harvested has facilitated studies in the horse of the actions of steroids and non-steroidal anti-inflammatory drugs (NSAIDS). Blockade of the synthesis of eicosanoids and suppression of inflammatory heat by clinical dose rates of NSAIDS suggests a causal link between the two events and provides further evidence for a role of these compounds in acute equine inflammation. The tendency for enolic and carboxylic acids NSAIDS to accumulate in inflammatory exudate may account for the duration of action of these compounds in inhibiting exudate eicosanoid synthesis and the data confirm clinical experiences with these drugs. A novel NSAID which inhibits both cyclo-oxygenase and lipoxygenase pathways of arachidonic acid metabolism, BW540C, and two anti-inflammatory steroids, betamethasone and dexamethasone, have been evaluated in the models of equine inflammation with some interesting and unexpected findings. This paper emphasises the interrelationships between the inflammatory process and the actions and fate of anti-inflammatory drugs. 相似文献

Abstract: Cats are popular pets, but until recently, their peri-operative and traumatic pain had been seriously underestimated and under-treated. The lack of treatment stems from difficulty in recognizing pain, lack of licensed analgesic drugs, fear of toxic side effects, and lack of information specific to cats. Fortunately, in the last decade, many advances have been made in feline analgesia. It is now obvious that because of the cat's unique metabolism, species-specific studies are essential. Opioids are the mainstay of any analgesic protocol for acute pain and can be used with few side effects. Other drugs that can be utilized include the α2 -agonists, local anesthetics, and non-steroidal anti-inflammatory drugs. Pain assessment in cats is challenging and developing, and validating pain scoring systems remains an important goal. The information in this article will help the critical care and emergency clinician formulate a safe and effective analgesic plan for feline patients. 相似文献

PRACTICAL RELEVANCE: Osteoarthritis (OA) is very common in the cat and in many cases is associated with significant long-term pain, which limits mobility and activity, and severely compromises the animal's quality of life. CLINICAL CHALLENGES: The treatment of chronic arthritic pain is a major challenge and many analgesic drugs used in other species are not licensed, not available or not tested for use in the cat. Many older cats with painful OA have some degree of chronic kidney disease (CKD) and many clinicians are reluctant to use non-steroidal anti-inflammatory drugs (NSAIDs) in these animals because of the potential for nephrotoxicity. EVIDENCE BASE: There are several publications that show that meloxicam is an effective NSAID for the cat and can be used long-term. It is easy to administer and there is published evidence that meloxicam can actually slow the progression of CKD in this species. Many other drugs are used to treat chronic pain in the cat but there is no documented evidence of their efficacy in OA. Unlike the dog, there is limited evidence for the effectiveness of omega-3 fatty acid-rich diets in managing feline OA and further work is required. There is no published data as yet for the usefulness or otherwise of nutraceuticals (glucosamine and chondroitin) in managing feline OA; studies in the authors' clinic suggest some pain-relieving effect. Research into environmental enrichment as a way of improving quality of life in cats with painful OA is lacking, but it is an approach worth using where possible. Modifications to the environment (eg, provision of comfortable bedding and ramps) are also important. 相似文献

Nonsteroidal anti-inflammatory drugs (NSAIDs) are used to control acute and chronic pain as well as to manage oncologic and neurologic diseases in human and veterinary patients. Despite ongoing research and efforts to improve the safety and efficacy of existing drugs, adverse effects such as gastrointestinal irritation, renal and hepatic toxicity, interference with hemostasis, and reproductive problems persist. The true incidence of NSAID-induced adverse effects in animals is unknown, but is likely underestimated, because cats and dogs may be more sensitive than humans to NSAIDs due to alterations in drug metabolism, absorption, and enterohepatic recirculation. NSAIDs produce both analgesia and toxic adverse effects primarily by inhibiting cyclooxygenase (COX), thereby decreasing the production of prostaglandins that signal inflammation and pain as well as mediate physiologic functions such as platelet aggregation, gastric protection, and electrolyte balance in the kidney. The presence of at least 2 COX isoforms may account for variability in NSAID efficacy and toxicity both within and among species. This paper reviews and evaluates the published literature on the safety, pharmacology, uses, and complications of a subclass of COX-1-sparing drugs, the coxibs, in veterinary medicine. Coxibs and other COX-1-sparing drugs provide a clinically useful improvement over traditional NSAIDs, but data are incomplete and more in vivo species-specific, target-tissue, and clinical studies are needed. 相似文献

Three dogs were referred to The Queen's Veterinary School Hospital at University of Cambridge for chronic behavioural or locomotor disorders associated with pain. All three had been unsuccessfully treated with conventional analgesics, including non-steroidal anti-inflammatory drugs, glucocorticoids and opiate agonists, prior to referral, with minimal or no response. They were investigated by neurological examination plus conventional ancillary diagnostic tests and therapeutic drug trials. Ruling out other causes of pain and applying previously well-described criteria, each case was diagnosed as consistent with neuropathic pain, a poorly recognised condition in domestic dogs. Treatment with the tricyclic antidepressant drug, amitriptyline, or the antiepileptic drug, gabapentin, resulted in either a dramatic improvement or full resolution of clinical signs in all cases. 相似文献

Randomized placebo-controlled crossover studies were carried out in dogs to evaluate how two non-steroidal anti-inflammatory drugs (NSAID) might modulate an acute post-traumatic inflammatory reaction. Two "identical" surgical interventions were performed on the forelimbs of each animal with an interval of 28 days, to enable a paired comparison of the inflammatory signs and the wound/bone healing processes. At one operation 8 dogs received 300 mg phenylbutazone twice daily for 8 days starting on the day before surgery, and at the other operation matching placebo tablets were given. In a similar placebo-controlled trial another group of 8 dogs received 5 mg indomethacin twice daily. With phenylbutazone the post-operative swelling was not significantly reduced compared to placebo, but there was less pain and limping. With indomethacin the swelling was somewhat reduced, but there was no consistent difference to placebo in the pain and limping assessments. None of the drugs appeared to distinctly effect the wound or fracture healing, as evaluated by clinical inspection, comparison of radiographs and comparison of bone sections from the sites of surgery. It proved difficult to select an appropriate dosage of indomethacin due to its high potential to induce GI ulceration and bleeding in dogs. In this experimental surgical model with an acute inflammation, neither phenylbutazone nor indomethacin showed impressive anti-inflammatory or analgesic properties. In the same model paracetamol has proved to significantly and more efficiently, reduce both swelling and pain without any noticeable adverse effects, and appears to be a better alternative than the two presently tested NSAID. 相似文献

Cyclooxygenase (COX) inhibitors and the intestine 总被引：1，自引：0，他引：1

Nonsteroidal anti-inflammatory drugs (NSAIDs) have long been used for the treatment of pain and inflammation because of their inhibitory effects on cyclooxygenase (COX). For almost as long as NSAIDs have been in use, multiple adverse effects have been noted. Assessment of many of these adverse effects have been complicated because of the discovery of multiple splice variants of the cox gene, and a greater array of COX inhibitors, especially the COX-2 selective inhibitors have become available. Some of these adverse effects cannot be readily explained by the effect of these drugs on COX. This has sparked a new field of investigation into the COX-independent effects of the COX inhibitors. The major noncyclooxygenase targets of the COX inhibitors of particular relevance to inflammation and the gastrointestinal tract are phosphatidylinositol 3'-kinase Akt signaling, uncoupling of oxidative phosphorylation, PPARgamma, nuclear factor KB, mitogen activated protein kinases, and heat shock proteins. 相似文献

The ability of two non-steroidal anti-inflammatory drugs to modify the clinical manifestations of pain associated with locomotor disease was assessed. Sixty-nine cats with acute or chronic locomotor disorders were recruited from 14 first opinion UK veterinary practices and randomly allocated to one of two treatment groups. Group A received meloxicam drops (0.3 mg/kg orally on day 1 followed by 0.1 mg/kg daily for four more consecutive days) and group B received ketoprofen tablets (1.0 mg/kg orally once daily for five days). Each cat underwent a full clinical examination before treatment, 24 hours after initiation of treatment and 24 hours after completion of treatment. General clinical parameters (demeanour and feed intake) and specific locomotor parameters (weightbearing, lameness, local inflammation and pain on palpation) were scored using a discontinuous scale scoring system. The two groups did not differ in terms of age, weight, gender distribution or duration of clinical signs; nor did they differ in terms of general clinical or specific locomotor scores pretreatment. Both treatment regimens resulted in a significant improvement in demeanour, feed intake and weightbearing, and a significant reduction in lameness, pain on palpation and inflammation. No significant difference was observed between the two treatment groups with respect to any of the parameters measured and both treatments were associated with minimal observed side effects. Meloxicam and ketoprofen were found to be effective analgesics and well tolerated in cats with acute or chronic locomotor disorders when administered for short-term treatment (five days) in such cases. However, meloxicam was assessed to be significantly more palatable than ketoprofen. 相似文献
