title: Antibacterial activity of the antiinflammatory agent diclofenac sodium.
abstract: Antimicrobial property of ten antiinflammatory drugs was tested with eleven sensitive bacteria belonging to both Gram positive and Gram negative types. Since most of the bacteria were moderate to highly sensitive to diclofenac (Dc), this compound was tested in vitro against 397 bacteria, most of which were inhibited by Dc at 50-100 micrograms/ml level. When tested in vivo, Dc at 1.5 and 3.0 micrograms/g body weight of a Swiss strain of white mice, could significantly protect the animals challenged with 50 MLD of Salmonella typhimurium NCTC 74. According to chi 2 test the in vivo data were highly significant (P < 0.001).
