Piroxicam, a member of the chemical class of nonsteroidal anti-inflammatory agents, is N-heterocyclic carboxamides of 1,2-benzothiazine-1,1-dioxide. It is an amphoteric compound. It exhibits a weakly acidic 4-hydroxy proton (pKa 5.1) and a weakly basic pyridinyl nitrogen (pKa 1.8) as determined by ultraviolet absorption spectrophotometry in methanol-water (2.5/97.5, v/v) solvent medium.
Piroxicam occurs as a white to off-white crystalline solid, poorly soluble in water, dilute acid and most organic solvents. It is slightly soluble in alcohols and in aqueous alkaline solution.
