Can Naproxen Help You Live Longer?

There may be a hidden benefit to the pain reliever naproxen. The non-steroidal anti-inflammatory drug (NSAID) is primarily used to treat arthritis, muscle aches and joint pain, but might also give a boost to your life expectancy, according to the results of a preliminary study.
An international research team analyzed 12-years of health records for over 500,000 people enrolled in the UK Biobank study to see if prescription drugs taken for at least 3 months were associated with higher or lower death rates. Over 400 medications were studied, with patients who were prescribed the drugs compared to control groups that didn’t take them.
“As expected, most drugs harbor a negative effect on lifespan, probably due to the underlying negative effect of the disease the drug is intended for. Importantly, a few drugs seem to have a beneficial effect on lifespan,” wrote lead author Alejandro Ocampo, PhD, a professor at the University of Lausanne and CEO of Epiterna, a Swiss company studying ways to slow the ageing process.
Ocampo and his colleagues identified four medications associated with lower death rates:
Naproxen
Atorvastatin (a statin)
Estradiol (female hormone replacement)
Sildenafil (Viagra)
Statins have long been known to reduce the risk of heart attack and stroke, while estradiol lowers the risk of osteoporosis and bone fractures in post-menopausal women. Sildenafil is well known for treating erectile dysfunction, but also improves cardiovascular health and may even protect against Alzheimer's disease. It’s easy to see how those drugs might increase life expectancy.
The inclusion of naproxen is a bit of a surprise. The active ingredient in Aleve and other over-the-counter pain relievers, naproxen raises the risk of a heart attack, stroke or internal bleeding when taken in high doses or used long-term. High doses of naproxen in 250mg and 500mg tablets are available by prescription, which is what people in the study were taking.
Even at those high doses, researchers found that naproxen was associated with a 10% lower death rate when compared to people who didn’t take the drug. The protective effect was strongest for men on naproxen, who had mortality rates that were 13% lower.
The findings are preliminary, have not been peer-reviewed, and don’t establish a cause-and-effect relationship. We don’t know why or how naproxen helps people live longer, only that it’s associated with a longer lifespan.
Interestingly, the research team found that two other pain relievers – morphine and paracetamol (acetaminophen) – are associated with shorter lifespans. Again, this may have more to do with the underlying conditions the drugs were prescribed for, rather than the medications themselves.
Ocampo says more research and clinical studies are needed to get a better understanding of the long-term harms and benefits of medication.
“The benefit on lifespan observed for several drugs in this retrospective study could only be truly determined by performing randomized controlled trials. Such studies would aim at treating a healthy aging population with a drug during a sufficiently long follow-up to be able to observe the effect on all-cause mortality,” Ocampo wrote.
If the life expectancy benefits are proven, researchers say it could result in some drugs being “repurposed” as anti-aging treatments for otherwise healthy older adults.
