Original Abstract of the Article

Main Research Findings

Diflunisal is a long-acting, non-steroidal anti-inflammatory drug (NSAID) that has been shown to be effective in reducing pain associated with osteoarthritis of the knee. 31 , 24 , 25 , 18 . It has also been found to be effective in treating postmeniscectomy pain, although it was less effective than ketorolac tromethamine. 21 . However, diflunisal can cause gastrointestinal side effects, especially at higher doses. 31 , 21 , 24 , 25 , 22 , 17 , 28 , 29 , 20 , 19 , 3 , 8 , 2 , 6 , 23 , 30 .

Reasons for Side Effects

Diflunisal works by inhibiting the production of prostaglandins, which are chemicals in the body that cause pain and inflammation. However, prostaglandins also play a role in protecting the gastrointestinal system. Therefore, diflunisal can inhibit the production of prostaglandins that protect the gastrointestinal system, leading to gastrointestinal side effects. 11

Common Side Effects

Gastrointestinal Side Effects

The most common side effects of diflunisal are gastrointestinal side effects. Diflunisal can cause stomach ulcers, dyspepsia, gastrointestinal disturbances, and bleeding. These side effects occur because diflunisal inhibits the production of prostaglandins that protect the gastrointestinal system. 11 , 24 , 20 , 29 , 22 , 17 , 8 , , 6 , 2 , 23 , 30 .

Hepatic Side Effects

Diflunisal can cause hepatic side effects. These side effects occur because diflunisal can directly damage liver cells. 13 , 12 .

Renal Side Effects

Diflunisal can cause renal side effects. These side effects occur because diflunisal can reduce blood flow to the kidneys. 11 , .

Other Side Effects

Diflunisal can also cause side effects such as dizziness, headache, and tinnitus. These side effects occur because diflunisal can affect the central nervous system. 24 , 20 , 17 , 23 .

Side Effect Management

Gastrointestinal Side Effects

To reduce the risk of gastrointestinal side effects, diflunisal is recommended to be taken with food. Diflunisal can also be combined with medications used to prevent or treat stomach ulcers. 11 , 24 , 20 , 29 , 22 , 17 , 8 , , 6 , 2 , 23 , 30 .

Hepatic Side Effects

To reduce the risk of hepatic side effects, regular liver function tests are recommended. 13 , 12 .

Renal Side Effects

To reduce the risk of renal side effects, regular kidney function tests are recommended. People with kidney disease should consult their doctor before taking diflunisal. 11 , .

Other Side Effects

Diflunisal can cause side effects such as dizziness, headache, and tinnitus. If you experience these side effects, consult your doctor. 24 , 20 , 17 , 23 .

Comparison Across Studies

Commonalities

Multiple studies have shown that diflunisal is effective in treating pain associated with osteoarthritis of the knee. 31 , 24 , 25 , 18

Differences

The effectiveness and side effects of diflunisal can vary across studies. For instance, one study found that diflunisal was more effective than naproxen. 27 , 18 , 25 . However, another study found that diflunisal and naproxen showed similar levels of effectiveness. 18 . Also, one study demonstrated that higher doses of diflunisal were more likely to cause gastrointestinal side effects than lower doses. 31

Real-World Application Considerations

Diflunisal is an effective medication for treating pain associated with osteoarthritis of the knee. However, it is important to note that diflunisal can cause gastrointestinal side effects. People with stomach ulcers or gastrointestinal diseases should consult their doctor before taking diflunisal. 11 , 24 , 20 , 29 , 22 , 17 , 8 , , 6 , 2 , 23 , 30 .

Limitations of Current Research

Many studies on diflunisal are small-scale and require larger studies to further validate their findings. 31 , 27 , 24 , 22 , 19 , 18 , 26 , 25 .

Future Research Directions

Larger and longer-term studies on diflunisal are needed. 31 , 27 , 24 , 22 , 19 , 18 , 26 , 25 .

Conclusion

Diflunisal is an effective medication for treating pain associated with osteoarthritis of the knee. However, it is important to be aware of its potential gastrointestinal side effects. It is crucial to consult your doctor before taking diflunisal. 31 , 27 , 24 , 22 , 19 , 18 , 26 , 25 .
