SGLT-2 Inhibitors as Calorie Restriction Mimetics

SGLT-2 inhibitors, or gliflozins, are a newer and still expensive class of anti-diabetic drug. They work by interfering in the trafficking of glucose, preventing the kidney from reclaiming glucose and introducing it back into the bloodstream. The glucose is instead excreted. Analogously to metformin, another anti-diabetic drug, it is proposed that inhibition of SGLT-2 in some ways mimic the effects of calorie restriction, triggering beneficial cellular housekeeping mechanisms that usually only turn on during periods of fasting or low calorie intake. Size of effect and degree of side-effects are always the questions in these matters, however. One should hold back any nascent enthusiasm until able to find reliable answers in the literature.

Evidently, a faction of the research community thinks that metformin has a large enough effect size to run a human trial versus aging, in order to push the FDA into accepting aging as an indication. Following that same line of thinking, these researchers would probably also consider this strategy for one or more SGLT-2 inhibitors. That said, one of the points of using metformin as the lever, to try to make the FDA reconsider aging as a medical condition that can be treated, is that metformin is very widely used and has a long history of use. Not that it is particularly effective in the grand scheme of things. It is hard for the FDA to object to it on any grounds other than aging not being a formally defined and approved medical condit...
