Creator description · original language
Brief exposure with rapamycin has the same positive effects on lifespan and health in old age as a lifelong treatment, researchers from the Max Planck Institute for Biology of Aging show in fruit flies and mice. Rapamycin is currently the most promising anti-aging drug. To maximize the medicine's effectiveness, it is often administered for life. However, even at low doses used to prevent age-related decline, side effects can occur. Therefore, the shorter duration of treatment may make it more likely to be used in humans.

Zeitfenster für Rapamycin: Kurze Einnahme hat gleiche Wirkung wie lebenslange Behandlung
Eine kurze Behandlung mit Rapamycin hat die gleichen positiven Auswirkungen auf die Lebenszeit und die Gesundheit im Alter, wie eine lebenslange Behandlung, zeigen Forschende vom Max-Planck-Institut für Biologie des Alterns an Fruchtfliegen und Mäusen. Rapamycin ist das derzeit vielversprechendste Anti-Aging-Mittel. Allerdings wird es, um die maximale Wirksamkeit des Medikaments zu erzielen, oft lebenslang verabreicht. Doch selbst bei niedrigen Dosierungen, die zur Vorbeugung von altersbedingtem Verfall verwendet werden, können Nebenwirkungen auftreten. Daher könnte die kürzere Behandlungsdauer die Anwendung im Menschen wahrscheinlicher machen.
