A study recently published in the journal Aging Cell found that administering rilmenidine, a medication used to treat hypertension, to animals at both young and older ages increases lifespan and enhances overall health markers, similar to the effects of caloric restriction.
Researchers have discovered that the hypertension drug rilmenidine can extend lifespan and slow aging.
New research findings, published on January 20 in the journal Aging Cell, show that animals treated with rilmenidine, currently used to treat hypertension (high blood pressure), at young and older ages increase lifespan and improve health markers, mimicking the effects of caloric restriction. Rilmenidine, which is a prescription medication, is marketed under the brand names Albarel, Hyperium, Iterium, and Tenaxum.
They also demonstrate that the healthspan and lifespan benefits of rilmenidine treatment in the roundworm C. elegans are mediated by the I1-imidazoline receptor nish-1, identifying this receptor as a potential longevity target.
Unlike other drugs previously studied for this purpose by the researchers, the widely-prescribed, oral antihypertensive rilmenidine has the potential for future translatability to humans as side effects are rare and non-severe.
To date, a caloric restriction diet has been considered the most robust anti-aging intervention, promoting longevity across
