Effect of mucoprotective plant-derived therapies on damage to colonic mucosa caused by carprofen and robenacoxib administered to healthy dogs for 21 days

Clinical outcomes and prognostic factors associated with nonsteroidal anti-inflammatory drug overdose in dogs presented to an emergency room

OBJECTIVE

To describe case presentations, clinical signs, and outcomes following nonsteroidal anti-inflammatory drug (NSAID) overdose in a clinical population of dogs and to identify factors associated with various outcomes including death or euthanasia, acute kidney injury, and suspected gastrointestinal ulceration (GIU).

DESIGN

Retrospective study.

SETTING

University teaching hospital.

ANIMALS

One hundred twenty-five client-owned dogs presenting to an emergency room for NSAID overdose between January 2006 and December 2017.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

Vomiting was the most common clinical sign, seen in 46 of 125 dogs (36.8%). Acute kidney injury and suspected GIU were seen in 17 (13.6%) and 16 dogs (12.8%), respectively. Thirty-two dogs (25.6%) ingested veterinary-formulated NSAIDs and 93 (74.4%) ingested human-formulated NSAIDs. No difference in any outcomes was seen between these two groups. One hundred twenty dogs (96%) survived to discharge. In multivariable analysis, the only significant finding was of the number of days of anorexia increased the risk of death or euthanasia with an odds ratio of 2.7 (95% confidence interval [1.14-6.5], P = 0.02).

CONCLUSIONS

Acute kidney injury and suspected GIU were seen less frequently than vomiting. Similar outcomes were seen for dogs ingesting veterinary- versus human-formulated NSAIDs. Owners presenting dogs with a longer duration of anorexia may be more apt to euthanize. As this was a clinical population of dogs presenting to an emergency room, findings may be more broadly applicable to the general population than prior studies utilizing poison control center data.

Gastroprotectants in small animal veterinary practice - a review of the evidence. Part 1: cyto-protective drugs

Diverse drugs with presumed cytoprotective effect have been used therapeutically in small animal veterinary practice for various gastro-intestinal conditions such as oesophagitis, gastric ulceration, gastritis or chronic gastro-enteropathies. Their efficacy has been doubted in human medicine, raising similar questions in the veterinary field. The aim of this review was to assess the current evidence on the efficacy and safety of these drugs in dogs and cats. Through a systematic review of the literature, we identified 37 articles on the use of misoprostol, sucralfate and other gastroprotectants in dogs and cats. There was evidence to support use of misoprostol in the prevention of aspirin-induced gastroduodenal mucosal injury in dogs, and for use of sucralfate in the prevention of acid-induced oesophagitis in cats. However, the overall quality of evidence supporting the use of these drugs in small animal patients was poor. In contrast, there was evidence of important adverse effects, especially drug interaction and gastro-intestinal signs. We therefore recommend prescribing these drugs with caution until further well-conducted studies reveal a useful gastroprotectant effect.
