One of the world ’s most commonly take drugs could be even more good than advertize . A new study this month demonstrate that metformin may potentially slow aging in the soundbox and brain of monkey . While more research in humans will be needed to confirm these findings , the drug is both cheap and already widely useable .
Metformin is an invaluable drug that ’s long been safely used to cover case 2 diabetes and is on the World Health Organization’slist of substantive medicines . In these individuals , it assist lower their blood sugar grade . Metformin has also been used an off - recording label medication for weight expiration ( with modest effects ) and to manage symptom of the hormonal precondition polycystic ovary syndrome , or PCOS . Over the years , some research has suggested that the drug ’s bodily burden , peculiarly in deoxidise excitation , might make it even more utilitarian . The most tantalizing of these studies havesuggestedthat Glucophage can amend brain functioning and slow down cognitive declivity in sometime patients . While metformin may not directly protract our life , it could peradventure lengthen our “ healthspan“—the amount of time we spend in comparatively good health .
Much of the grounds for metformin ’s anti - senescent benefits has come from indirect observational data or from studies of creature that are n’t too closely related to humanity , such asrodents . But in their new studypublishedlast week in the journalCell , a big group of research worker in China have taken an important whole tone frontward in direct this data col .

The scientists deal a 40 - month - tenacious field of study with adult manful cynomolgus imp ( Macaca fasciucularis ) , roughly adequate to 13 yr of human life . They on a regular basis render Glucophage to 12 erstwhile imp during that study period , and equate the health of these monkey to two dissimilar ascendence groups not given the drug : one group of 16 old monkeys and another grouping of 18 young to middle - senior monkeys .
Based on an extensive regalia of tests , including brain scans , the researchers created a fashion model to estimate the monkeys ’ gestate and actual biologic years across unlike organs . And the monkeys on metformin lean to show signs of slower aging compared to elderly monkeys not take the drug , particularly when it came to their livers and brain . According to the research worker ’ calculations , the Glucophage had made these imp ’ brains six years vernal on average , which could potentially understand to 18 years in man .
“ Our inquiry pioneers the systemic diminution of multi - dimensional biological historic period in primates through metformin , paving the fashion for advancing pharmaceutic scheme against human aging , ” the researchers wrote .
This appear to be the first unmediated examination of metformin ’s anti - aging potential in primates . But the written report ’s finding are still based on a small sample size of it , and cynomolgus monkeys may have crucial biologic differences that could dissemble the action of Glucophage . These caveats mean that we ca n’t be certain about metformin ’s fount - of - youth effect in humans , at least not yet . But the results certainly do provide more bonus to keep excavate .
A Common Diabetes Drug May Reduce Long Covid Risk , Trial Data discover
The researchers have already get down to work , in partnership with the company Merck , on aPhase II trialthat will test Glucophage as an anti - senescent drug in 120 people . And this is n’t the only potential victory for Glucophage this month . On Tuesday , researcher shop by the NIHpublished a studyfinding that people taking Glucophage for their diabetes were less probable to die from their covid-19 infection or to develop prospicient covid than people taking other diabetes drugs — the latest objet d’art of evidence to suggest that metformin could be a valuablelong covid discourse .
