Ibuprofen’s impact on the liver: What you need to know

Ibuprofen is a widely used drug, often reached for to ease pain and lower fever. It belongs to a category known as nonsteroidal anti-inflammatory drugs, or NSAIDs. People take it regularly for everything from headaches to muscle soreness.

While many are aware that ibuprofen can sometimes negatively affect the heart and possibly increase the risk of a stroke, its influence on the liver has not been as clear.

Recent research carried out by scientists at the University of California Davis has shed light on just how significant ibuprofen’s effect on the liver might be, revealing that the drug could have a more profound impact than what was previously understood, especially noting differences between men and women.

The research team, led by Professor Aldrin Gomes, conducted an experiment where they gave mice a moderate amount of ibuprofen for a week.

This dosage mirrored what an adult human might take daily—about 400 mg, which is roughly the amount in a typical over-the-counter ibuprofen pill.

To analyze the effects of ibuprofen, the scientists used a sophisticated technique known as mass spectrometry, which allowed them to observe detailed changes in the liver cells at a molecular level.

What they found was quite surprising: the ibuprofen triggered significant alterations in the liver, affecting at least 34 distinct metabolic pathways in male mice alone.

These pathways are crucial for the body’s processing of amino acids, hormones, and vitamins. They also influence how the liver handles harmful substances like reactive oxygen and hydrogen peroxide, which are byproducts of normal cell activities but can damage cells if they accumulate.

One of the intriguing findings was that ibuprofen’s impact varied significantly between male and female mice. In particular, the drug affected how proteins were managed and disposed of within liver cells.

For instance, the proteasome, which acts like a recycling center for proteins, responded differently in males compared to females.

This suggests that ibuprofen could alter how quickly other drugs are broken down in the body, potentially leading to drugs staying in the system longer in males than in females.

The study’s findings are important because they suggest that the differences between how males and females process drugs like ibuprofen are significant and should be considered more carefully in both medical research and healthcare.

Furthermore, the results underscore a broader concern that commonly used drugs like ibuprofen might be overused and not always appropriate for mild conditions. This overuse could lead to unintended health issues over the long term, particularly concerning liver health.

The implications of this study are vast. It calls for a heightened awareness among the scientific community and the public about the potentially serious side effects of routinely used medications like ibuprofen, particularly regarding long-term liver health.

It also highlights the necessity of considering gender differences in how drugs are metabolized and their subsequent effects on health.

This groundbreaking research has been published in the journal Scientific Reports and opens the door for further studies to better understand the safe use of NSAIDs like ibuprofen, ensuring they are used more judiciously to minimize risks and maximize benefits.
