Inhibitory Effects of Aspirin and Ibuprofen Overdose on Cholinesterase Activity: and Studies.

BACKGROUND

In recent years, it has been reported that long-term use of Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) may have protective effects against neurodegenerative diseases by inhibiting the activity of cholinesterase enzymes. The exact biological mechanism of these protective effects is not yet known. This study aims to assess the and effects of aspirin and ibuprofen injection on the activity of acetylcholinesterase and butyrylcholinesterase.

MATERIALS AND METHODS

In this experimental study, 70 adult male mice (20-25 g) were divided randomly into 7 groups (n= 10) including a control group that received normal saline and other groups that received different dosages of aspirin and ibuprofen (100, 200, and 300 mg/kg) in the form of intraperitoneal injection. Mice were anesthetized by ether, and blood samples were taken from the heart. Ellman´s methods were used to measure cholinesterase, erythrocytes, and serum, respectively.

RESULTS

The activity of cholinesterase enzymes in serum and erythrocytes decreased significantly (P<0.0001) in treated groups with aspirin and ibuprofen compared to the control samples after 3 and 24 hours. However, these inhibitory effects were variable depending on the dose of the injected drugs, and they were statistically significant at higher injection doses and analysis.

CONCLUSION

The result of this study showed that non-steroidal anti-inflammatory drugs can inhibit the activity of the cholinesterase enzymes in both and conditions compared to the control group.
