Abstract:

Non-steroidal anti-inflammatory drugs (NSAIDs) are commonly used in veterinary medicine. Additionally, interest in the anti-inflammatory properties of phytochemicals has emerged in recent years. In the present study, we aim to investigate the in vitro effects of meloxicam, flunixin meglumine, and harpagoside on the respiratory burst of porcine polypharmonuclear neutrophils (PMNs). We observed that harpagoside was able to suppress the respiratory burst, similar to flunixin meglumine. Conversely, meloxicam enhanced the PMNs response. However, these effects were only detected at concentrations higher than those achievable in plasma and tissues. The present study intends to offer insights into the role of these molecules on phagocytosis mechanisms in animals to complement what is already known regarding human PMNs.
