Do non-steroidal anti-inflammatory drugs induce sister chromatid exchanges in T lymphocytes?
The genetic toxicity of non-steroidal anti-inflammatory drugs was investigated using the sister chromatid exchange technique in cultured human lymphocytes. A total of 48 patients were treated with non-steroidal anti-inflammatory drugs (ibuprofen, ketoprofen, naproxen, indomethacin, diclofenac or acetylsalicylic acid) for 2 weeks. The average numbers of sister chromatid exchanges in cultured lymphocytes from the patients, before and after treatment with these drugs, did not differ significantly (P > 0.05). These results indicate that treatment with non-steroidal anti-inflammatory drugs for 2 weeks does not induce sister chromatid exchanges in T lymphocytes.
