Aging is a normal part of life, but it also increases the risk of many health problems.
As people get older, cells and organs gradually become less efficient, making conditions such as heart disease, diabetes, cancer, and memory problems more common.
Scientists are therefore looking for ways to extend “healthspan,” the years of life spent in good health. The goal is not simply to help people live longer, but to help them remain healthier and more independent as they age.
One approach that has attracted attention is calorie restriction. In laboratory studies, animals that eat fewer calories while still receiving enough nutrients can sometimes live longer and develop fewer age-related problems.
But severe calorie restriction is difficult for people to maintain and may not be suitable or safe for everyone. This has encouraged researchers to search for medicines that might produce some of the same biological effects without requiring people to follow a very restrictive diet.
Researchers led by scientists at the University of Liverpool investigated an unexpected candidate: rilmenidine. The medicine is already used in some countries to treat high blood pressure, but the researchers wanted to know whether it might also influence aging.
The team studied rilmenidine mainly in a tiny worm called Caenorhabditis elegans, or C. elegans. These worms are widely used in aging research because they have a short lifespan, allowing scientists to study changes across an entire lifetime relatively quickly.
Worms treated with rilmenidine lived longer than untreated worms. They also showed improvements in measures of health during both younger and older stages of life, suggesting that the drug affected more than lifespan alone.
The researchers found that many of the changes produced by rilmenidine were similar to those associated with calorie restriction. This raised the possibility that the medicine may imitate some of the beneficial biological responses normally triggered when calorie intake is reduced.
The team also investigated how the drug might produce these effects. Their experiments pointed to a cell receptor called the I1-imidazoline receptor, which appears to be important for rilmenidine’s effects.
Further experiments in mice found changes in gene activity in the liver and kidney that were also linked to calorie restriction. This provided additional evidence that rilmenidine may influence some of the biological pathways involved in aging.
Rilmenidine is especially interesting because it is already an established medicine rather than a completely new experimental chemical. It is taken by mouth and has been used to lower blood pressure, so doctors already know considerably more about its effects in patients than they would about a newly discovered compound.
However, that does not mean people should take rilmenidine in an attempt to slow aging. A medicine that extends life in worms or produces promising biological changes in mice may not have the same effect on human lifespan or healthy aging.
Human aging is far more complicated, and drugs can have different effects depending on a person’s health, other medicines, and many other factors. Clinical studies would be needed to determine whether rilmenidine can safely provide meaningful anti-aging benefits in people.
The research was carried out by scientists including João Pedro de Magalhães and colleagues and was published in the journal Aging Cell. The findings provide a starting point for further investigation into whether existing medicines could be repurposed to promote healthier aging.
For now, proven habits remain much more important than experimental anti-aging treatments. Regular physical activity, nutritious food, adequate sleep, avoiding smoking, and managing conditions such as high blood pressure can all help protect health as people grow older.
If you care about blood pressure, please read studies about blood pressure drug that may increase risk of sudden cardiac arrest, and these teas could help reduce high blood pressure.
For more health information, please see recent studies about nutrient that could strongly lower high blood pressure, and results showing this novel antioxidant may help reverse blood vessels aging by 20 years.
