aldecoxib [systematic name: 4-(5-methyl-3-phenyl­isoxazol-4-yl)benzene­sulfonamide], C16H14N2O3S, a diaryl-substituted isoxazole, is a non-steroidal anti-inflammatory drug (NSAID) that is used for the treatment of rheumatoid arthritis, osteoarthritis and dysmenorrhea pain. The planar isoxazole ring is oriented at angles of 22.2 (1) and 54.3 (1)° with respect to the phenyl and benzene­sulfonamide groups, respectively. N-H...O and C-H...O hydrogen bonds and N-H...[pi], C-H...[pi] and [pi]-[pi] interactions stabilize the crystal packing.
