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.  相似文献

To evaluate the effect of licofelone, an arachidonic acid substrate with combined inhibitory activity against 5-lipoxygenase and cyclooxygenases 1 and 2, a double-blind, randomised and placebo-controlled study was conducted in 33 client-owned dogs that were lame owing to hindlimb osteoarthritis. Seventeen of the dogs received a placebo and 16 were treated with 2.5 mg/kg licofelone twice a day for 28 days. The dogs' lameness was assessed on a visual analogue scale (vas), and by force plate analyses at baseline and 14 and 28 days after starting the treatment. After 14 days the mean (se) change in peak vertical force in the licofelone-treated dogs (1.7 [0.8] per cent bodyweight) was significantly greater (P<0.05) than in the placebo-treated dogs (-0.3 [0.6] per cent bodyweight), and after 28 days the difference had increased. In contrast, the dogs' lameness, as assessed by the vas values, had decreased significantly over baseline in both the treated and control groups.  相似文献

OBJECTIVES: The efficacy of maropitant (Cerenia; Pfizer Inc.) as an anti-emetic for use in dogs with ongoing emesis was evaluated in a two-phase multi-centric study conducted at veterinary clinics in France, Italy, Slovakia and the UK. METHODS: In phase I, dogs with ongoing emesis were randomised in a 1:1 ratio to either maropitant (32 dogs) or metoclopramide (34 dogs). In phase II, dogs were randomised in a 2:1 ratio to maropitant (77 dogs) or metoclopramide (40 dogs). Maropitant was administered subcutaneously at 1 mg/kg/day for up to five days. Metoclopramide was administered as recommended on the product labels as licensed at 0.5 to 1 mg/kg/day subcutaneously or orally with the daily dose divided over two to three administrations per day for up to three to five days. RESULTS: In phase I, 97 per cent of dogs treated with maropitant and 71 per cent of dogs treated with metoclopramide did not vomit after treatment (P<0.01). The mean number of emetic events after maropitant treatment was significantly reduced compared with that after metoclopramide treatment (P=0.01). In phase II, the occurrence of emesis was lower for maropitant during the first 24 hours (P<0.0001) and for each day thereafter. CLINICAL SIGNIFICANCE: A single daily dose of maropitant was more effective than metoclopramide administered two or three times daily in the treatment of emesis caused by various aetiologies in dogs.  相似文献

The safety of dirlotapide in dogs was evaluated in two studies with parallel designs. In an acute tolerance study, 24 beagles (six dogs per treatment) were treated orally once daily for 14 days with placebo or dirlotapide at 2.5, 5.0, or 10.0 mg/kg/day. In a margin-of-safety study, 38 overweight, neutered beagles were treated orally once daily for 3 months with dirlotapide at doses up to 0.5 mg/kg/day (six dogs), 1.5 mg/kg/day (12 dogs) and 2.5 mg/kg/day (six dogs). Control dogs received placebo at 0.3 mL/kg/day (10 dogs) and 0.5 mL/kg/day (four dogs). Results were similar for both studies, and no serious adverse events were observed. Dirlotapide was clinically well-tolerated in dogs at dosages up to 10 mg/kg/day for 14 days and 2.5 mg/kg/day for 3 months. Dirlotapide produced the expected decrease in food intake and body weight (up to 20–40%) without ill effects. Clinical, pathologic, and histopathologic findings were reversible and consistent with suppression of food intake and rapid weight loss produced by elevated dirlotapide dosages. In both studies, sporadic emesis and loose stools were observed in both placebo and dirlotapide-treated dogs. Incidence of emesis generally increased with dose and decreased with treatment time. Elevations in hepatic transaminase activity were seen in dogs treated with more than 1.5 mg/kg dirlotapide daily, but were not associated with clinical signs or microscopic evidence of hepatic degeneration or necrosis.  相似文献

To compare the efficacy, tolerability and safety of a generic formulation of ciclosporin for human beings with prednisone in the treatment of canine atopic dermatitis), human generic ciclosporin A (hgCsA) (5 mg/kg daily) and prednisone (1 mg/kg daily for seven days, followed by 1 mg/kg every second day) were administered to 13 and seven dogs with atopic dermatitis, respectively, for 42 days. Skin changes were assessed using a modified canine atopic dermatitis extent and severity index (mCADESI-01) and a pruritus intensity scale system. The in vitro functional capacity of phagocytic cells was assessed using the tetrazolium reductase activity and zymosan-stimulated tetrazolium reductase activity tests, as well as measurements of the percentage phagocytic activity and the ingestion capacity of phagocytic cells. Haematological and biochemical parameters were also monitored. There was a greater than or equal to 50 per cent reduction from the baseline in mCADESI-01 scores in 84.6 and 100 per cent of dogs, and a greater than or equal to 50 per cent reduction from the baseline in pruritus scores in 76.9 and 85.7 per cent of dogs, treated with hgCsA and prednisone, respectively. No important adverse physical, haematological or biochemical effects occurred with either drug and no statistically significant changes were detected in any of the four tests assessing the functional activity of phagocytes. The generic formulation of ciclosporin was effective in reducing the severity of physical signs of canine atopic dermatitis and was well tolerated.  相似文献

A double-blind, randomised, controlled, multicentre field study was conducted to compare the safety and efficacy of firocoxib chewable tablets and carprofen tablets in 218 dogs with osteoarthritis. Firocoxib is a non-steroidal anti-inflammatory drug with more than 350-fold selectivity in dogs for the inducible isoform of the enzyme cyclo-oxygenase-2. The efficacy, tolerance and ease of administration of firocoxib (5 mg/kg/day) and carprofen (4 mg/kg/day) were assessed by the owners and the attending veterinarians during 30 days of treatment. The efficacy was assessed in terms of the dogs' overall scores at the end of the treatment, based on the veterinarians' assessment of lameness, pain on manipulation/palpation, range of motion, and joint swelling; 92.5 per cent of the dogs treated with firocoxib and 92.4 per cent of the dogs treated with carprofen had improved. The reduction in lameness in the dogs treated with firocoxib was significantly greater than in the dogs treated with carprofen. The owners' evaluations were that 96.2 per cent of the dogs treated with firocoxib and 92.4 per cent of the dogs treated with carprofen had improved, and this difference was statistically significant.  相似文献

Ketoconazole (Nizoral®, Janssen Pharmaceutica) a new systemic antimycotic was tested in dermatomycosis in cats and dogs. The daily dose (10 mg/kg body weight) was administered for 10 or 20 days without any other measures being taken. After the 20‐day treatments new hair growth was observed in 96.7 per cent of the cats and 89.9 percent of the dogs. Clinical cure was complete in 96.8 per cent of the cats and 90.5 per cent of the dogs.

Particularly the good tolerance in the cat was appreciated. There were practically no side‐effects in dogs (except vomiting in two pups) or in cats.  相似文献

Thirty-nine client-owned dogs with osteoarthritis were treated with 5 mg/kg firocoxib administered orally, once a day for 52 weeks. Veterinary examinations were performed on approximately days 0, 15, 90, 180, 270 and 360. Twenty-five dogs completed the study. The withdrawal rate associated with gastrointestinal side effects was low (5.1 per cent of dogs). Based on the owners' assessment, 82 per cent of the dogs had improved at day 15, 84 per cent of the 32 remaining dogs had improved at day 90, and 96 per cent of the 25 dogs that completed the trial had improved at day 360. During this trial, 12 (48 per cent) of the 25 remaining dogs showed an improvement in their lameness from day 90 to day 360 (P<0.05).  相似文献

O bjectives : To investigate effects and side effects of aglepristone in terminating pregnancy in bitches.
M ethods : Twenty-two bitches were treated in mid-pregnancy with subcutaneous injections of aglepristone at a total dose of 20 mg/kg. Short-term follow-up (one to two weeks after treatment) included clinical examination and abdominal ultrasonography in 18 of the dogs. Long-term telephone follow-up was recorded for all 22 dogs.
R esults : Pregnancy was terminated in 21 bitches (95 per cent). Signs of abortion occurred one to eight days after treatment. Vaginal discharge was evident in 17 (77 per cent) dogs. Obvious signs of parturition were seen in nine (41 per cent) dogs. Eight dogs (36 per cent) developed anorexia, and in two (9 per cent) of the dogs a local reaction at the injection site was evident. Two dogs developed pyometra two and four years after treatment, respectively.
C linical S ignificance : Aglepristone, when administered in mid-gestation, is effective in terminating pregnancy. Side effects are few and transient.  相似文献

Tablets of micronised nitroscanate (nominal particle size 2--3 microns) were given to a total of 190 dogs that had been experimentally infected with either Echinococcus granulosus or Taenia hydatigena. The efficiency of the drug in tablet form in freeing dogs from tapeworms, was investigated. The dose rate at which 50 per cent of normally fed dogs can be expected to be freed from E granulosus was found to be 89 mg/kg (95 per cent confidence limits 55 mg/kg to 140 mg/kg). The 90 per cent effective dose rate was not determined within the range 32 mg/kg to 250 mg/kg. The dose rate at which 90 per cent of normally fed dogs can be expected to be freed from T hydatigena was 37 mg/kg (95 per cent confidence limits 23 mg/kg to 60 mg/kg).  相似文献

OBJECTIVE: To determine whether postoperative administration of ketoprofen or carprofen had any effects on short- or long-term results of femoral head and neck excision (FHNE) in dogs. DESIGN: Prospective randomized controlled trial. ANIMALS: 40 client-owned, large-breed dogs undergoing FHNE and 15 healthy large-breed dogs used as controls for hip joint angle measurements and force plate analyses. PROCEDURE: Dogs undergoing FHNE were treated with ketoprofen, carprofen, or a placebo for 21 days after surgery. Hip joint abduction and extension angles were measured at the end of surgery and 120 days later. Lameness scores were assigned, and force plate analyses were performed on days 3, 15, and 120. RESULTS: There were no significant differences among treatment groups in regard to hip joint angles or lameness scores. Force plate analysis revealed that dogs in all 3 treatment groups bore consistently less weight on the operated limb than did control dogs for the duration of the study. Dogs receiving ketoprofen had greater peak propulsive force at a walk on day 3 and greater peak vertical force at a walk on day 15 than did dogs receiving the placebo. Treatment of an acute condition and preservation of the lesser trochanter, but not postoperative analgesic administration, were positively associated with ground reaction forces on day 120. Owners of 12 of 31 dogs indicated that the dog's gait worsened for a few days after discontinuation of analgesic administration. CONCLUSIONS AND CLINICAL RELEVANCE: Administration of ketoprofen or carprofen after surgery was not associated with long-term results of FHNE, probably because of the impact of other factors. Because some owners noticed worsening of the lameness following cessation of analgesic administration in the present study, it is possible that longer administration would have improved long-term results.  相似文献

Rats undergoing laparotomy received either carprofen (5 mg/kg) or ketoprofen (5 mg/kg) administered orally in flavoured gelatin, or by subcutaneous injection. A control group that received no analgesic showed a significant (3 per cent) fall in bodyweight (P = 0.009) after laparotomy. This decrease was greater than that seen in the groups receiving carprofen (P = 0.006) or ketoprofen (P = 0.012) administered subcutaneously, which continued to gain weight following surgery. All animals showed a significant fall in food consumption but this decrease was greater in the jelly alone group (47 per cent) than in the group receiving carprofen (17 per cent) (P = 0.015) administered subcutaneously. A significant fall in water consumption occurred in the control group (40 per cent) and in animals that received oral carprofen (13 per cent) or Ketoprofen (22 per cent). No significant decrease was seen in groups receiving either carprofen or ketoprofen administered subcutaneously (P > 0.1). This study shows that a relatively simple surgical procedure results in a major reduction in food and water consumption in rats. This reduction can be minimised by the administration of ketoprofen or carprofen (5 mg/kg subcutaneously), but higher dose rates are required if these drugs are to be administered by the oral route.  相似文献

OBJECTIVES: The clinical efficacy and safety of imidapril were evaluated in dogs that presented with mild to severe congestive heart failure (New York Heart Association stage II to IV) by comparing the success rate of imidapril with a positive control by a non-inferiority approach. METHODS: This good, clinical practice compliant, multicentre study (EFFIC study) enrolled 142 client-owned dogs and was conducted in 20 locations in France, Belgium and Germany. Dogs of various breed, age and weight were included in the study. These dogs were randomised into two groups that were treated for 84 days with either the test product, imidapril, or the positive control, benazepril, and followed up in parallel over this period. Both treatments were administered at a dose of 0.25 mg/kg once a day with the possibility of doubling this dose to 0.5 mg/kg if considered necessary from a clinical point of view. In addition, concomitant treatment was given to dogs presenting with pulmonary oedema and/or ascites, supraventricular tachyarrhythmia and/or dilated cardiomyopathy. The evolution of the New York Heart Association stage and the "functional signs" score were evaluated as primary efficacy criteria. RESULTS: The success rate in the imidapril group was 66 compared with 68 per cent in the benazepril group. Regarding safety, 35 dogs in each group experienced at least one adverse event. Nine dogs in each group experienced at least one serious adverse event. The difference between these results was not statistically significant. CLINICAL SIGNIFICANCE: Imidapril is as efficacious and safe as the reference product, benazepril.  相似文献

The kinetics and efficacy of a cinchophen prednisolone combination preparation (PLT) were assessed in the dog. Cinchophen administered at a dose rate of 12-5 mg/kg intravenously had a volume of distribution (Vd area) of 0–13 litres/kg, a clearance rate (Cl) of 0–15 litres/h and a half-life (t 1/2β of 7–92 hours. Following oral administration the bioavailability was 87-21 per cent. Prednisolone administered at a dose rate of 0–15 mg/kg intravenously had a Vd area of 2–7 litres/kg, a CI of 0–116 litres/h and a t1/2β of 1–11 hours. PLT given to dogs with osteoarthritis at a dosage range of between 25 and 44 mg/kg per day cinchophen and between 0–125 and 0–220 mg/kg per day prednisolone for a maximum of 14 days significantly improved lameness (P<0–001), weight bearing (P<0–005), joint mobility (P<0–01) and stiffness (P<0–001) scores and was similar in clinical efficacy to phenylbutazone.  相似文献

One hundred and twenty-nine dogs with pituitary-dependent hyperadrenocorticism were treated according to a protocol aimed at the complete destruction of the adrenal cortices by the administration of o,p'-DDD (mitotane) at a daily dose of 50 to 75 mg/kg bodyweight for 25 days. On the third day, glucocorticoid and mineralocorticoid supplementation was begun for the induced adrenocortical insufficiency. The first followup examination after completion of the 25-day course and the subsequent twice-yearly follow-up examinations included physical examination and measurements of plasma concentrations of sodium and potassium to optimise substitution therapy. In 19 dogs the full course of 25 days treatment could not be completed. Of the 110 dogs which received the full course of treatment, the administration had to be stopped temporarily in 32 because of side-effects, such as anorexia and vomiting. The actual dose of o,p'-DDD administered was not significantly different in the dogs with and without these side-effects. Clinical remission occurred in 111 dogs (86 per cent), of which 43 (39 per cent) had a relapse. The estimated one-year disease-free fraction was 77 per cent (95 per cent confidence interval [CI]: 67 to 85 per cent). The estimated one-year survival fraction was 80 per cent (95 per cent CI: 71 to 87 per cent), the two-year survival was 69 per cent (95 per cent CI: 59 to 78 per cent), and the three-year survival was 61 per cent (95 per cent CI: 49 to 71 per cent). The bodyweight and age of the dog, and vomiting occurring during the period of treatment, were positively correlated with the length of the disease-free period, whereas weakness during the treatment and resistance to dexamethasone suppression of the urinary corticoid/creatinine ratios at the start of the treatment were associated with a relatively short survival time.  相似文献

Reasons for performing study: Lameness is a highly prevalent condition in horses and the principal cause of removal from athletic activity. In clinical studies to evaluate nonsteroidal anti‐inflammatory drug therapies, force plates are commonly used to assess improvement of lameness objectively. Hypothesis: To use a force plate to determine the optimal dose of a new COX‐2 inhibitor (firocoxib) that will reduce lameness, when administered orally to horses once daily. Methods: Sixty‐four horses that exhibited chronic lameness presumed due to osteoarthritis, including navicular disease, in at least one of the frontlimbs and at a stable level of severity, were included. Horses were treated per os s.i.d. for 7 days as follows: vehicle control, firocoxib at 0.05, 0.1 or 0.25 mg/kg bwt. Force plate analysis of each horse was done for the selected (most) lame frontlimb at trot. Once between Days ?19 and ?4 (initial examination), and again on Day ?2 or ?1 (baseline), pretreatment force plate assessments were performed, and thereafter horses were assessed on Days 0, 2 and 6, approximately 10 h post treatment each time. Peak vertical force (PVF) and lameness grades at initial examination and at baseline, and their change from baseline in the 4 different treatment groups were analysed statistically at a significance level of P<0.05. Results: The PVF results were found to be superior to vehicle control already at Day 0 for 0.25 mg/kg bwt and at Days 2 and 6 for 0.1 and 0.25 mg/kg bwt (P<0.05). Mean clinical lameness for both concentrations decreased >1 grade at Day 6. Conclusions and clinical relevance: With the dosage of 0.25 mg/kg bwt lameness did not improve more than with 0.1 mg/kg bwt. Thus, 0.1 mg/kg bwt s.i.d. was considered to be the effective dose at reducing chronic lameness in horses presumed due to osteoarthritis, including navicular disease.  相似文献

OBJECTIVE: To evaluate effects of meloxicam on severity of lameness and other clinical signs in dogs with osteoarthritis (OA). DESIGN: Randomized, controlled, multicenter clinical trial. ANIMALS: 217 client-owned dogs with clinical and radiographic signs of OA. PROCEDURE: Dogs were randomly assigned to be treated with meloxicam (n = 105; 0.2 mg/kg [0.09 mg/lb], SC, once on day 1, then 0.1 mg/kg [0.045 mg/lb], PO, q 24 h, for 13 days) or a placebo (n = 112). A general clinical score was assigned by investigators on days 1 (ie, prior to initiation of treatment), 8, and 15 on the basis of severity of lameness, extent of weight bearing, and severity of signs during palpation of the affected joint. Owners and investigators provided overall evaluations on days 8 and 15. RESULTS: Dogs treated with meloxicam had significantly greater improvements in general clinical scores, compared with baseline scores, on days 8 and 15 than did dogs treated with placebo. On days 8 and 15, percentages of dogs treated with meloxicam in which owners and investigators considered treatment to be successful were significantly higher than percentages of control dogs in which treatment was considered to be successful. No abnormalities in hematologic and serum biochemical test results were detected. CONCLUSIONS AND CLINICAL RELEVANCE: Results suggest that compared with administration of a placebo, administration of meloxicam for 14 days significantly improved the clinical condition of dogs with OA without causing adverse effects.  相似文献

The efficacy, safety and palatability of a new flavoured chewable anthelmintic tablet were investigated in dogs. The efficacy, based on worm counts, of a single recommended therapeutic dose (RTD) of 5 mg pyrantel + 20 mg oxantel + 5 mg praziquantel/kg bodyweight was assessed in experimental infections (EI) and natural infections (NI) with Trichuris vulpis, Echinococcus granulosus and Toxocara canis. For T vulpis, the efficacy of the treatment was 99.3 per cent in EI (comparing groups of six treated and six control dogs) and 100 per cent in NI (nine treated and nine control dogs). For E granulosus, the efficacy was more than 99.9 per cent in EI (11 treated and 11 control dogs). For T canis, the efficacy was 94.3 per cent in EI (10 treated and 10 control dogs) and 100 per cent in NI (12 treated and 13 control dogs). In a field study, Ancylostoma caninum (11 dogs) and T canis (11 dogs) faecal egg counts were reduced by more than 99 per cent, and in eight dogs with Dipylidium caninum proglotides in the faeces the efficacy was 100 per cent. The tablets were readily consumed by 56 of 64 (87.5 per cent) privately owned dogs. Safety was assessed in groups of six dogs treated either once with twice the RTD, once with six times the RTD, with twice the RTD on three consecutive days, or untreated. There were no significant differences in blood parameters between the groups, and no abnormal clinical findings. Two dogs treated with six times the RTD vomited, but no vomiting was observed when administration was repeated two days later.  相似文献

Results of long-term treatment were evaluated in 200 dogs with primary hypoadrenocorticism and 5 dogs with spontaneous secondary hypoadrenocorticism. Fludrocortisone acetate initially was used for mineralocorticoid replacement in 190 of the dogs with primary hypoadrenocorticism. The daily dose of fludrocortisone required in these dogs increased significantly during the treatment period (median, 2.6 years) from an initial median dose of 13.1 μg/kg to a final dose of 22.6 μg/kg. In 27 of the 200 dogs, mineralocorticoid therapy was changed from fludrocortisone to desoxycorticosterone pivalate (DOCP) because of adverse effects, poor response, or financial considerations. The dose of DOCP required in the 33 dogs (27 dogs plus 6 dogs initially given DOCP) increased significantly during the treatment period (median, 3.5 years) from an initial median dose of 1.56 mg/kg to a final dose of 1.69 mg/kg; the interval between DOCP injections ranged from 14 to 35 days (median, 30 days). The dose of prednisone administered to the dogs with primary hypoadrenocorticism decreased significantly from an initial median dose of 0.3 mg/kg to a final dose of 0.2 mg/kg; the drug was discontinued in 22 dogs due to adverse effects. The 5 dogs with secondary hypoadrenocorticism received only glucocorticoid replacement therapy (prednisone) at initial and final daily dosages of 0.41 mg/kg and 0.25 mg/kg, respectively, during a median treatment period of 4.4 years. More than 80% of the dogs were considered to have a good to excellent response to therapy. The median survival time of all 205 dogs was 4.7 years. There were no differences in response to treatment or survival between dogs treated with fludrocortisone and those receiving DOCP, or between dogs with primary hypoadrenocorticism and those with secondary hypoadrenocorticism.  相似文献
