Naproxen, sulindac and salicylate, three NSAIDs (non-steroidal anti-inflammatory drugs), were cytotoxic to human colorectal cancer cells in culture. Toxicity was accompanied by significant depletion of intracellular polyamine content. Inhibition of ornithine decarboxylase (the first enzyme of the polyamine biosynthetic pathway), induction of polyamine oxidase and spermidine/spermine N(1)-acetyltransferase (the enzymes responsible for polyamine catabolism) and induction of polyamine export all contributed to the decreased intracellular polyamine content. Morphological examination of the cells showed typical signs of apoptosis, and this was confirmed by DNA fragmentation and measurement of caspase-3-like activity. Re-addition of spermidine to the cells partially prevented apoptosis and recovered the cell number. Thus polyamines appear to be an integral part of the signalling pathway mediating NSAID toxicity in human colorectal cancer cells, and may therefore also be important in cancer chemoprevention in humans.

Ketoprofen lysine salt (Artrosilene) Fiale) is a non-steroidal anti-inflammatory agent frequently administered by intravenous infusion in association regimen with other drugs, such as steroidal anti-inflammatory, anti-hemorrhagic, anti-spastic, anti-ulcer, and antibacterial drugs. The aim of this study was to investigate the physicochemical compatibility between ketoprofen lysine salt (Artrosilene) Fiale) and other injectable drugs frequently used in association. Physicochemical properties of ketoprofen lysine salt mixtures with different drugs, including colour, clarity, pH and drug content were observed or measured before and after (up to 5 h) mixing at room temperature and under light protection. Results show that the association of Artrosilene Fiale with different drugs does not cause, up to 5 h from mixing, any significant variation in the physicochemical parameters mentioned above. In conclusion, the results obtained demonstrated the physicochemical compatibility of ketoprofen lysine salt (Artrosilene) Fiale) with several drugs.
