Injectable or transdermal flunixin meglumine improves pregnancy rates in embryo transfer recipient beef cows without altering returns to estrus. Theriogenology 2019; 140:8-17. [PMID: 31421533 DOI: 10.1016/j.theriogenology.2019.08.011] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2019] [Revised: 07/10/2019] [Accepted: 08/07/2019] [Indexed: 12/31/2022]
Abstract
OBJECTIVES were to determine effects of 1) injectable or transdermal flunixin meglumine (FM) at embryo transfer (ET) compared to an untreated control group on pregnancy per ET (P/ET; ∼35 d after ET); 2) embryo and recipient factors on P/ET; 3) FM on hormone concentrations; and 4) FM on returns to estrus. Angus-cross beef cows (n = 1145) at five locations were scored for body condition (BCS; 1-9) and temperament (0 or 1) and given Select-Synch + CIDR. Recipient cows with a corpus luteum (CL) ≥1.5 cm received a frozen-thawed embryo 7 d after estrus and were concurrently given 1.1 mg/kg injectable FM im (INJFM; n = 384), 3.3 mg/kg transdermal FM pour on (TDFM; n = 388), or nothing (CON group; n = 373). Blood samples were collected at ET and 7 d later (60 cows). Accounting for temperament (P < 0.05), ET difficulty score (1-3, easy to difficult; P < 0.01), treatment by temperament (P < 0.001) and treatment by embryo quality (P < 0.05), FM treatments affected P/ET (P < 0.05). The P/ET for cows given INJFM [62.8% (241/384)] or TDFM [58.7% (228/388)] were not different (P = 0.26), but they were greater (P = 0.01 and P = 0.04, respectively) than P/ET for controls [51.2% (191/373)]. The P/ET was greater for calm versus excitable cows, 60.2 (463/769) and 52.4% (197/376), respectively (P < 0.01) and was lower for difficulty score 3 [49.2% (156/317)] compared to score 1 [62.7% (254/405; P < 0.001) or score 2 [59.1% (250/423; P < 0.01)]. There was no effect (P > 0.1) of cow age, BCS, or stage of embryo development on P/ET. Pregnancy rates for embryo quality grade 1 (excellent/good) and grade 2 (fair) were 60.4% (314/520) and 55.4% (346/625), respectively (P > 0.05). Percentages of non-pregnant recipient cows in estrus from Days 18-26 did not differ among treatment groups (P > 0.1). Control cows had lower progesterone concentrations and greater substance-P, PGFM and 8-isoprostane PGF2α concentrations at 7 d after ET compared to FM-treated cows (P < 0.05). In conclusion, injectable or transdermal FM improved pregnancy rates in ET recipients, without affecting nonpregnant cows return to estrus.

The Safety and Pharmacokinetics of Carprofen, Flunixin and Phenylbutazone in the Cape Vulture (Gyps coprotheres) following Oral Exposure. PLoS One 2015; 10:e0141419. [PMID: 26512724 PMCID: PMC4626400 DOI: 10.1371/journal.pone.0141419] [Citation(s) in RCA: 25] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2015] [Accepted: 10/08/2015] [Indexed: 11/19/2022] Open
Abstract
The following study evaluates the overt toxic potential of carprofen (CRP), flunixin (FXN) and phenylbutazone (PBZ) in Old world vultures in relation to historic toxicity data for diclofenac and ketoprofen, with the Cape vulture (Gyps coprotheres) being the indicator species. The toxic potential of a single oral dose of CRP (11.5 mg/kg), FXN (1 mg/kg),PBZ (1.7 mg/kg) or water was evaluated by means of a four-way parallel study (n = 2), as means of ascertaining if these drugs were as toxic as diclofenac in the vulture. No unscheduled deaths or pathological lesions were noted following exposure. Clinical signs of lethargy and depression were, however, noted in one CRP, two FXN and one PBZ treated birds. Mild reversible inhibition of UA excretion was evident in all three groups, although UA remained within the population reference interval in contrast to the effects previously described for diclofenac and ketoprofen. All treatment groups had a drug concentration responsive increase in alanine transferase activity. CRP, FXN and PBZ were characterised by a maximum plasma concentration (Cmax) of 1051.8 ± 620.7 ng/ml, 335.9 ± 36.3 ng/ml and 11150 ± 2474.9 ng/ml at 4 ± 4.3, 0.45 ± 0.02 and 5.3 ± 5.2 hours (Tmax) respectively and a half-life of elimination of 13.3 ±5, 1.8±1 and 18.7 ±11.4 hours respectively. While we could not demonstrate a lethal effect of the tested substances, the presence of toxic clinical signs, clinical pathological changes and/or long half-lives of elimination suggests that all three drugs have a potential for toxicity in a larger population or on repeat administration. In conclusion while the studied substances were not as overtly toxic as diclofenac, they are of safety concern.

The effects of perioperative analgesia on litter size in Crl:CD1(ICR) mice undergoing embryo transfer. JOURNAL OF THE AMERICAN ASSOCIATION FOR LABORATORY ANIMAL SCIENCE : JAALAS 2010; 49:423-426. [PMID: 20819387 PMCID: PMC2919181] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Subscribe] [Scholar Register] [Received: 09/18/2009] [Revised: 10/15/2009] [Accepted: 01/26/2010] [Indexed: 05/29/2023]
Abstract
The objective of this study was to evaluate the effect on litter size of 2 analgesics used perioperatively during mouse embryo transfer surgery. Day 2.5 pseudopregnant CD1 mice (n = 96) were divided equally into 2 analgesic treatment groups and a saline control group. Each mouse received a single, subcutaneous dose of buprenorphine hydrochloride (0.1 mg/kg), flunixin meglumine (2.5 mg/kg), or saline immediately after induction of anesthesia with 2.5% isoflurane. Each mouse then was prepared for aseptic surgery. Blastocysts had previously been collected from C57BL/6NCrl female mice that were synchronized and superovulated by using pregnant mare serum gonadotropin and human chorionic gonadotropin and mated with C57BL/6NTac male mice 3.5 d before collection. Viable blastocysts were pooled, and 8 were selected arbitrarily and transplanted into the right uterine horn of each pseudopregnant CD1 mouse. Mice were monitored throughout pregnancy, and the number of pups at birth was documented. No statistically significant difference was found between the 3 groups. These results indicate that perioperative analgesic treatment with buprenorphine or flunixin in the CD1 mouse undergoing embryo transfer is not associated with increased embryonic loss.

Abstract
CASE DESCRIPTION A 6-month-old male Bactrian camel was examined because of a 3-week history of lameness of the left hind limb. CLINICAL FINDINGS Lameness was initially detected in the left hind limb but resolved and was detected in the right hind limb during treatment. Lameness increased during periods of rapid growth. Radiography revealed multiple small opacities of the medullary cavity of several long bones throughout treatment. Core bone biopsies of lesions in the tibiae revealed lamellar bone with areas of loose connective tissue, osteoblasts in the medullary cavity, and periosteal new bone formation, all which were consistent with panosteitis. TREATMENT AND OUTCOME Palliative treatment was attempted with epidural and transdermal administration of analgesics. Flunixin meglumine was administered PO, which coincided with an abrupt increase in serum creatinine concentration. Performance of multiple diagnostic bone biopsies led to remission of clinical signs of pain. CLINICAL RELEVANCE Panosteitis should be a differential diagnosis for shifting limb lameness in young camels. Bone biopsies can be useful for diagnosis of panosteitis and possible relief of pain associated with the disease. Bactrian camels may be susceptible to the renal toxicity of flunixin meglumine, especially when dehydrated.

Abstract
Objectives of these studies were to determine the effects of flunixin meglumine (FM) administration on early embryonic mortality and circulating PG and cortisol concentrations in transported and non-transported cows. Cows (n = 483) from 3 locations were used to evaluate the effects of transportation and FM approximately 14 d after AI on the establishment of pregnancy and serum concentrations of progesterone, PGF metabolite (PGFM), and cortisol. Treatments were transport (n = 129), transport + FM (n = 128), no transport (n = 130), and no transport + FM (n = 96). Multiparous cows (n = 224) were used at 2 locations, and nulliparous cows (n = 259) were used at 1 location. The no transport + FM treatment was used at only 2 locations. Flunixin meglumine (approximately 1.1 mg/kg of BW; i.m.) was administered before the cows were separated into transportation groups. Transportation included 4 to 6 h of transportation, without calves, via semitractor trailer. Nontransported cows remained penned, with their calves in adjacent pens, during the same period as the transported cows. Blood samples were collected from all cows before and after treatment and, at 2 locations, approximately 3 h after the onset of treatment. Location affected AI pregnancy rate (P < 0.01). Treatment effects, although not significant (P = 0.16), were of a magnitude to be considered practically important. Cows that received transportation + FM tended (P = 0.07) to have greater AI pregnancy rates (74%) than those that did not receive FM (66%), irrespective of transportation. Cortisol concentration was greater (P < 0.05) for transported cows than for nontransported cows. Cows receiving FM had greater (P < 0.05) AI pregnancy rates than non-FM cows (71 vs. 61%, respectively). Cows receiving transportation had lower (P < 0.01) mean PGFM concentrations than nontransported cows (45.4 vs. 54.6 pg/mL, respectively), and cows receiving FM had lower (P < 0.01) mean PGFM concentrations than non-FM cows (39.4 vs. 60.6, respectively). We conclude that transportation of cows approximately 14 d after AI increased serum cortisol concentrations but did not affect AI pregnancy rates. However, treatment of cows with FM increased AI pregnancy rates, irrespective of whether they were transported.

Abstract
OBJECTIVE To evaluate adverse effects of long-term oral administration of carprofen, etodolac, flunixin meglumine, ketoprofen, and meloxicam in dogs. ANIMALS 36 adult dogs. PROCEDURES Values for CBC, urinalysis, serum biochemical urinalyses, and occult blood in feces were investigated before and 7, 30, 60, and 90 days after daily oral administration (n = 6 dogs/group) of lactose (1 mg/kg, control treatment), etodolac (15 mg/kg), meloxicam (0.1 mg/kg), carprofen (4 mg/kg), and ketoprofen (2 mg/kg for 4 days, followed by 1 mg/kg daily thereafter) or flunixin (1 mg/kg for 3 days, with 4-day intervals). Gastroscopy was performed before and after the end of treatment. RESULTS For serum gamma-glutamyltransferase activity, values were significantly increased at day 30 in dogs treated with lactose, etodolac, and meloxicam within groups. Bleeding time was significantly increased in dogs treated with carprofen at 30 and 90 days, compared with baseline. At 7 days, bleeding time was significantly longer in dogs treated with meloxicam, ketoprofen, and flunixin, compared with control dogs. Clotting time increased significantly in all groups except those treated with etodolac. At day 90, clotting time was significantly shorter in flunixin-treated dogs, compared with lactose-treated dogs. Gastric lesions were detected in all dogs treated with etodolac, ketoprofen, and flunixin, and 1 of 6 treated with carprofen. CONCLUSIONS AND CLINICAL RELEVANCE Carprofen induced the lowest frequency of gastrointestinal adverse effects, followed by meloxicam. Monitoring for adverse effects should be considered when nonsteroidal anti-inflammatory drugs are used to treat dogs with chronic pain.

Abstract
Cyclooxygenase (COX) is a rate-limiting enzyme that catalyzes the conversion of arachidonic acid, an essential fatty acid present in cell membrane phospholipids and liberated by phospholipase, into prostaglandins (PGs) and prostanoids. COX has two distinct membrane-anchored isoenzymes; COX-1 and COX-2. COX-1 is a constitutively expressed and found in most normal body tissues; COX-2 is expressed in normal tissues at low levels and is highly induced by pro-inflammatory mediators in the setting of inflammation, injury, and pain. Inhibitors of COX activity include: (1) conventional non-selective non-steroidal anti-inflammatory drugs (ns-NSAIDs); (2) selective COX-2 inhibitors (COXIBs); and (3) COX-1 inhibitors. Non-selective NSAIDs, at therapeutic doses, inhibit both COX-1 and COX-2. The anti-inflammatory benefits of these drugs are primarily derived from COX-2 inhibition, while inhibition of COX-1 often elicits gastrointestinal (GI) toxicity. Therefore, COXIBs were developed to provide a selective COX-2 agent, i.e., one, that at fully therapeutic doses demonstrated comparable therapeutic benefit to non-selective NSAIDs, without the attendant COX-1-mediated GI toxicities. In this review, we evaluate available literature describing the pathophysiologic role of cyclooxygenases and the effects of their inhibition in GI system in experimental and domestic animal species.

Abstract
OBJECTIVE To assess effects of treatment with phenylbutazone (PBZ) or a combination of PBZ and flunixin meglumine in horses. ANIMALS 24 adult horses. PROCEDURE 13 horses received nonsteroidal antiinflammatory drugs (NSAIDs) in a crossover design. Eleven control horses were exposed to similar environmental conditions. Treated horses received PBZ (2.2 mg/kg, PO, q 12 h, for 5 days) and a combination of PBZ and flunixin meglumine (PBZ, 2.2 mg/kg, PO, q 12 h, for 5 days; flunixin meglumine, 1.1 mg/kg, IV, q 12 h, for 5 days). Serum samples were obtained on day 0 (first day of treatment) and day 5, and total protein, albumin, and globulin were measured. RESULTS 1 horse was euthanatized with severe hypoproteinemia, hypoalbuminemia, and colitis during the combination treatment. Comparisons revealed no significant difference between control horses and horses treated with PBZ alone. There was a significant difference between control and treated horses when administered a combination of PBZ and flunixin meglumine. Correction for horses with values >2 SDs from the mean revealed a significant difference between control horses and horses administered the combination treatment, between control horses and horses administered PBZ alone, and between horses receiving the combination treatment and PBZ alone. Gastroscopy of 4 horses revealed substantial gastric ulcers when receiving the combination NSAID treatment. CONCLUSIONS AND CLINICAL RELEVANCE Analysis of results of the study indicates the need for caution when administering a combination NSAID treatment to horses because the detrimental effects may outweigh any potential benefits.

Abstract
The clinical efficacy of two non-steroidal anti-inflammatory drugs (NSAIDs), meloxicam (Metacam 20 mg/ml) and flunixin meglumine (Finadyne), as adjuncts to antibacterial therapy in the treatment of acute febrile respiratory disease in cattle was compared. The randomised blind, positive controlled study was conducted under feedlot conditions in Mexico. Overall, 201 female cattle (weighing 220-250 kg) diagnosed with bronchopneumonia at the feedlot were recruited into the study. On Day 0 all animals were treated with 20 mg oxytetracycline/kg body-weight (Bivatop 200) by subcutaneous injection, in conjunction with either meloxicam (0.5 mg/kg subcutaneously, Metacam 20 mg/ml, n = 100), or flunixin meglumine (2.2 mg/kg intravenously, Finadyne, n = 101). According to label instructions, meloxicam was administered as a single dose, whereas flunixin meglumine could be administered daily for up to 3 consecutive days depending on the rectal temperature (with re-administration, if rectal temperature > or = 40.0 degrees C). Rectal temperature, respiratory rate, appetite, dyspnoea, coughing, nasal discharge and general condition were recorded on Days 0 (prior to treatment), 1, 2, 3 and 7 using a weighted numerical score. Scores were summed to generate a 'Clinical Sum Score' (CSS, range 7 to 24 points). Individual animal body weights were measured on Days 0 and 7. Nasal swabs were collected from 10 animals per treatment group on Day 0 for microbiological culture. Clinical parameters and the mean CSS showed no significant differences between treatment groups with mean CSS on Days 0 and 7 of 16.18 and 10.55 in the meloxicam group and 16.41 and 10.88 in the flunixin meglumine group. However, a significantly lower mean rectal temperature was measured in the meloxicam group on Day 2 (p < or = 0.01). No significant differences in mean body weights were found between groups. Repeated administration of flunixin meglumine was performed in 45% of the animals. No suspected adverse drug events related to treatments were reported. It is concluded that a single subcutaneous dose of meloxicam was as clinically effective as up to 3 consecutive daily intravenous doses of flunixin meglumine when used as an adjunctive therapy to antibacterial therapy in the treatment of acute febrile respiratory disease in feedlot cattle.

Abstract
A potential adverse effect of cyclo-oxygenase (COX) inhibitors (nonsteroidal anti-inflammatory drugs [NSAIDs]) in horses is colitis. In addition, we have previously shown an important role for COX-produced prostanoids in recovery of ischaemic-injured equine jejunum. It was hypothesised that the nonselective COX inhibitor flunixin would retard repair of bile-injured colon by preventing production of reparative prostaglandins, whereas the selective COX-2 inhibitor, etodolac would not inhibit repair as a result of continued COX-1 activity. Segments of the pelvic flexure were exposed to 1.5 mmol/l deoxycholate for 30 min, after which they were recovered for 4 h in Ussing chambers. Contrary to the proposed hypothesis, recovery of bile-injured colonic mucosa was not affected by flunixin or etodolac, despite significantly depressed prostanoid production. However, treatment of control tissue with flunixin led to increases in mucosal permeability, whereas treatment with etodolac had no significant effect. Therefore, although recovery from bile-induced colonic injury maybe independent of COX-elaborated prostanoids, treatment of control tissues with nonselective COX inhibitors may lead to marked increases in permeability. Alternatively, selective inhibition of COX-2 may reduce the incidence of adverse effects in horses requiring NSAID therapy.

Abstract
We studied 125 patients with primary dysmenorrhea in a prospective randomized double-blind crossover study. After an admission pretreatment period without medication, the patients completed three consecutive randomized treatment phases with lysine clonixinate 125 mg plus propinox 10 mg or paracetamol 500 mg plus hyoscine N-butylbromide 10 mg or placebo, according to a fixed-dose schedule of 1 tablet every 6 h, 3 days before onset of menses and for 5 days thereafter. Changes in menstrual pain intensity and duration, amount of bleeding measured according to the number of daily pads used and concomitant symptoms were assessed on the fifth day of each cycle. Every night, the patients recorded the average intensity of menstrual pain during the first 4 days of menstruation in a diary The follow-up visit carried out at day 5 showed significant reduction in pain intensity with both active treatments vs. the other two phases: baseline: 2.72 +/- 0.61; placebo: 1.85 +/- 0.87; lysine clonixinate plus propinox 1.36 +/- 0.81, and paracetamol plus hyosine N-butylbromide: 1.45 +/- 0.87. The patients' diaries showed increasingly lower pain intensities starting from day 1 with the three treatments. Active treatments revealed significantly higher analgesic efficacy from the outset compared with baseline and placebo; however, only the lysine clonixinate plus propinox combination reached a statistically significant difference by days 3 and 4. No changes in duration or intensity of menstrual bleeding or in the incidence of adverse effects were observed during the four study periods.

Abstract
In this study lysine clonixinate, a nonsteroidal antiinflammatory agent with selective inhibition of cyclooxygenase-2 and 5-lipooxygenase in in vitro and in vivo pharmacodynamic studies, was evaluated in a prospective, randomized, double-blind, double-dummy clinical study versus paracetamol/codeine, in 151 patients with pain following inguinal hernioplasty. Patients were treated with one 125 mg tablet of lysine clonixinate or paracetamol/codeine (500 mg + 30 mg) administered at fixed doses every 4 h during 2 days. Controls were carried out 1, 2 and 4 h after the first intake of day 1 and day 2. Each control included assessment of pain at rest, when coughing, sitting and upon moderate pressure. Both treatment groups (lysine clonixinate, 77 patients and paracetamol/codeine, 74 patients) were comparable in terms of demographic and baseline pain intensities. Spontaneous pain was reduced significantly in both treatment groups from the 1st-h control. The following values were recorded in the lysine clonixinate group during day 1: baseline: 6.86 +/- 1.24; 1st h: 4.49 +/- 1.77; 2nd h: 2.96 +/- 1.74; 4th h: 2.23 +/- 1.51. The following values for the same group during day 2 were: predose: 1.70 +/- 1.64; 1st h: 1.16 +/- 1.17; 2nd h: 0.78 +/- 1.06; 4th h: 0.63 +/- 1.05. The paracetamol/codeine group revealed the following values: day 1: baseline: 6.72 +/- 1.22; 1st h: 4.57 +/- 1.72; 2nd h: 2.97 +/- 1.68; 4th h: 2.47 +/- 1.68 and day 2: predose: 2.02 +/- 1.57; 1st h: 1.32 +/- 1.23; 2nd h: 0.82 +/- 0.99; 4th h: 0.66 +/- 0.89. Reduction of pain induced by coughing, sitting and pressure showed similar behavior patterns. No significant differences between both treatment groups were encountered in terms of analgesic efficacy. Incidence of adverse effects was significantly higher in the paracetamol/codeine group (X2: p < 0.05): 11 out of 74 patients; three patients had to discontinue treatment. In the lysine clonixinate group four out of 77 patients showed side effects but these did not require treatment discontinuation.

Abstract
Most studies of nonsteroidal anti-inflammatory drugs (NSAID) do not demonstrate appreciable differences in efficacy. As awareness of the adverse effects associated with NSAID use increases, safety is becoming the primary concern among physicians when selecting NSAID for use by their human patients. However, veterinarians may be less aware of the safety concerns associated with NSAID use. A wide range of NSAID is used to treat human beings with osteoarthrits; however, it is imperative to remember that dogs are especially sensitive to these drugs, and reports of serious, and occasionally fatal, complications are numerous. Carprofen is a propionic acid-derived NSAID that has anti-inflammatory, analgesic, and antipyretic activity. In animals, carprofen is as potent as indomethacina and more potent than aspirin or phenlbutazone, but carprofen appears to be safer than most other NSAID.

Abstract
Ketorolac tromethamine, a nonsteroidal anti-inflammatory analgesic, was compared with flunixin and butorphanol for its analgesic efficacy and potential side effects after laparotomy or shoulder arthrotomy in dogs. Sixty-four dogs were randomly assigned to receive butorphanol 0.4 mg/kg body weight (BW) (n = 21), flunixin 1.0 mg/kg BW (n = 21), or ketorolac 0.5 mg/kg BW (n = 22), in a double blind fashion. The analgesic efficacy was rated from 1 to 4 (1 = inadequate, 4 = excellent) for each dog. The average scores after laparotomy were ketorolac, 3.4; flunixin, 2.7; and butorphanol, 1.6. After shoulder arthrotomy, the average scores were ketorolac, 3.5; flunixin, 3.0; and butorphanol, 1.4 (5/11 dogs). As butorphanol was unable to control pain after shoulder arthrotomy, oxymorphone, 0.05 mg/kg BW, replaced butorphanol in a subsequent group of dogs and had a score of 2.0 (6/11 dogs). Serum alanine aminotransferase and creatinine were significantly elevated above baseline at 24 hours postoperatively in dogs receiving flunixin. One dog in each group developed melena or hematochezia. One dog receiving ketorolac had histological evidence of gastric ulceration. We concluded that ketorolac is a good analgesic for postoperative pain in dogs.

Gastroduodenal ulceration associated with flunixin meglumine administration in three dogs . J Am Vet Med Assoc 1993; 203:92-5.

Abstract
In 3 clinically ill dogs, signs of gastroduodenal ulceration were first noticed within 7 days of beginning flunixin meglumine administration and included pyrexia, anorexia, weight loss, vomiting, melena, pain on abdominal palpation, and abdominal distention. One dog was euthanatized and 2 dogs recovered after surgical repair of the perforated ulcers and treatment of peritonitis. Prolonged administration of flunixin meglumine should be avoided, especially in debilitated dogs or when concurrently administering other nonsteroidal anti-inflammatory drugs or corticosteroids.

Acute tubulo-interstitial nephritis in a dog after halothane anaesthesia and administration of flunixin meglumine and trimethoprim-sulphadiazine. Vet Rec 1992; 131:148-51.

Abstract
Acute tubulo-interstitial nephritis was diagnosed post mortem when a dog died four days after surgery for a femoral head resection. Possible causative factors associated with halothane anaesthesia, flunixin meglumine analgesia and prophylactic antibiotic therapy with trimethoprim-sulphadiazine are discussed. It is concluded that death was due to renal failure associated with tubulo-interstitial nephritis as a result of a combination of ischaemic and toxic events.

Abstract
Moderate to severe ulcerative colitis of the right dorsal colon was diagnosed by necropsy or by exploratory celiotomy and biopsy in 13 horses with a primary clinical complaint of either colic, diarrhea, or weight loss. Clinical signs varied from acute fulminating diarrhea (possibly with fever), colic, dehydration, endotoxic shock and death, to a chronic condition manifested by mild intermittent colic up to several months in duration, and weight loss with or without mild diarrhea. In a large percentage of the horses, those affected had been hypovolemic and received nonsteroidal anti-inflammatory drugs (NSAID) or had received inappropriately high doses of phenylbutazone before the onset of illness. Experimental treatment of two horses with high doses of a phenylbutazone oral paste preparation (6 gm once daily for 5 days) and limitation of their water intake to approximately one half of maintenance requirement (for 5 days) resulted in reproduction of ulcerative colitis involving only the right dorsal colon, which was apparent at necropsy examination 11 and 15 days after initiation of drug use. It was concluded that localized ulcerative lesions in the right dorsal colon may be a previously unreported manifestation of toxicity due to the administration of NSAID.
