→Side Effects and Contraindications
The side effects associated with the use of NSAIDs are related to theie non-specific inhibition of COX enzymes. The constitutively expressed COX-1 has many functions within the normal body, and suppression of these may lead to adverse reactions.

Gastro-intestinal prostaglandins (for example, PGI2 and PGE2) normally have a protective influence over the gastric mucosa, by inhibiting the secretion of gastric acid and promoting that of mucus. NSAID inhibition of COX-1 function leads to the reduced synthesis of these prostaglandins, causing '''ulceration of the gastro-intestinal tract'''. Lesions of the large intestine have also been demonstrated following the use of phenylbutazone in the horse. Although NSAIDs are normally absorbed in the stomach, phenylbutazone may bind to feed and become released in this more distal area of the tract resulting in ulceration.
