Phenylbutazone exerts its mechanism of action by inhibiting the activity of the enzyme cyclooxygenase, specifically the COX-1 and COX-2 isoforms. This inhibition leads to a decrease in the production of prostaglandins, which are lipid compounds involved in the inflammatory response. Its mechanism of action at the molecular level involves interfering with the arachidonic acid cascade, ultimately resulting in the suppression of inflammatory mediators.
