Ibuprofen May Lower Risk Of Parkinson’s Disease

Out of 146,948 participants, the study identified a total of 413 cases of Parkinson’s disease. The purpose was to identify whether the use of nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen is associated with a lower risk of Parkinson’s disease.

“Our previous study for the first time showed that regular users of non-aspirin NSAIDs had a lower risk of Parkinson’s disease than non-users. There has been evidence suggesting a role of neuro-inflammation in the disease process, and our previous study indicated that non-aspirin NSAIDs might be protective,” said lead author Honglei Chen, MD, PhD, of the Harvard School of Public Health and the National Institute of Environmental Health Sciences. The findings indicated that ibuprofen users had a 35 percent lower risk of Parkinson’s disease, and the results were similar in both men and women. The participants were tracked over the course of an average 8.5 years. The risk seemed to decrease depending on the weekly dosage. For people who took a daily ibuprofen tablet, the risk was 38 percent lower, compared to people who did not regularly take ibuprofen. The reason ibuprofen has an effect on the development of Parkinson’s remains unclear. “The mechanisms as to why ibuprofen protects against the disorder are not clear, and this is the area where we need more research,” said Chen. Age, gender, and smoking status — known risk factors for Parkinson’s disease — could not explain the results. No significant associations were found between the use of aspirin, other NSAIDs, or acetaminophen and the risk of Parkinson’s disease. (Source: American Academy of Neurology: April 2005.)
