PURPOSE: Non-steroidal anti-inflammatory drugs (NSAID) are frequently used in oral surgical procedures in dentistry. The evaluation of the frequency of sister chromatid exchange (SCE) is accepted as a reliable cytogenetic method to assess the genotoxic effects of environmental factors. MATERIALS AND METHODS: In this study, the genotoxic effects of various NSAIDs were assessed in 30 patients to who they were administered following encluosed third molar surgery using SCE analysis before and after the operation. The frequency of SCE was evaluated before the operation and after 3 days of etodolac, nimesulid and naproxen use. RESULTS: There was no statistically significant difference in the frequency of SCE between the preoperative and postoperative states in patients given etodolac, nimesulid or naproxen sodium. CONCLUSION: Short term use of selective and non-selective NSAIDs was not associated with a significant genotoxic effect that could be detected using the SCE method in peripheric lymphocytes.

OBJECTIVETo observe the rate of efficacy and adverse drug reaction of non-steroidal anti-inflammatory drugs (NSAIDs) in the population with osteoarthritis and rheumatoid arthritis, based on available clinical data.

METHODSUsing Meta analysis to evaluate the data of effect and safety profile of NSAIDs from 19 articles on randomized clinical trials published from 1990 to 2001 in Chinese journals. The total number of patients enrolled for evaluation on rates of effectiveness and adverse drug reaction were 1 732 and 2 925, respectively.

RESULTSData on the effect and safety were comparatively heterogeneous among different kinds of NSAIDs. The effective rates (95% CI) were as follows: nabunetone, 66.7% (61.9% - 71.4%); meloxicam, 68.4% (59.2% - 77.6%); naproxen, 64.5% (59.8% - 69.1%); nimesulide, 79.8% (75.7% - 84.0%); ibuprofen, 77.2% (70.7% - 83.8%); diclofenac, 77.1% (69.2% - 85.0%); oxaprozin, 65.8% (59.5% - 72.0%). Rates of adverse drug reaction (95% CI) were as follows: nabunetone, 16.3% (12.5% - 20.0%); meloxicam, 10.2% (4.2% - 16.2%); naproxen, 29.2% (24.8% - 33.6%); nimesulide, 20.2% (16.0% - 24.3%); ibuprofen, 16.7% (14.7% - 18.8%); diclofenac, 19.3% (11.9% - 26.7%); oxaprozin, 12.7% (8.9% - 16.7%) respectively.

CONCLUSIONThe rates of effect and adverse reaction on patients having osteoarthritis and rheumatoid arthritis with NSAIDs treatment would largely depend on the drugs being used. Within 2 - 8 weeks of treatment, the effective rate and rate of adverse drug reaction with commonly used NSAIDs as nabumeton, meloxicam, etc., were 59.2% - 85.0% and 4.2% - 33.6%, respectively.

Traditional non-steroidal anti-inflammatory drugs (NSAIDs) and COX-2 selective inhibitors are among the most widely used drugs. However, their significant side effects in gastrointestinal and cardiovascular systems limited the use of these drugs. Recently, research and development of NO-donating NSAIDs (NO-NSAIDs) have become one of the most important strategies to reduce these side effects. NO-NSAIDs may exert a broad range of positive effects in terms of NO-mediated gastrointestinal and cardiovascular safety as well as comparable or increased anti-inflammatory, analgesic properties relative to NSAIDs. This review briefly deals with chemistry of NO-NSAIDs, more details are focused on biological significance, mechanism of action, and therapeutic potential of this novel class of drugs.
