Abstract - Ketamine is widely used in equine anaesthesia. Beside its anaesthetic and analgesic properties, ketamine possesses a cytokine-modulating
activity. However, to date, no data are available regarding the inhibitory effect of ketamine on the cytokine response in
horses. In horses, cytokines such as tumour necrosis factor-alpha (TNF-
) and interleukin-6 (IL-6) play a pivotal role in the pathogenesis of equine endotoxaemia following gastrointestinal disorders.
Hence, the objective of this study was to assess the influence of ketamine on LPS-induced TNF-
and IL-6 formation in an equine macrophage cell line (eCAS cells). The results demonstrate a cytokine-modulating activity
of ketamine in an equine cell line, suggesting a beneficial role for ketamine in the treatment of equine endotoxaemia.
Key words: ketamine / cytokine / equine endotoxaemia / eCAS
