Where Can Americans Buy Rapamycin?
Bochum, June 2015 - People are getting older today. In addition to diabetes, the most common diseases in old age also include heart attacks, cancer and dementia. US researchers want to find out in a study whether the previous diabetes drug metformin can be used to extend the age of non-diabetics and whether age-related diseases can be delayed. The antidiabetic agent, which has been used for 60 years, has shown in previous studies that it can prevent cancer and help prevent cardiovascular diseases. The German Society for Endocrinology (DGE) is waiting with regard to the suspected positive effects of metformin in non-diabetics and advises waiting for ongoing studies. Because vitamin B12 deficiency with cognitive disorders can sometimes accompany metformin intake.
In mid-June, the journal "Nature" published an article about the planned TAME study with the diabetes drug Metformin (Targeting Aging with Metformin), in which it is to be investigated whether this drug can extend the life span of non-diabetics as well as age-related diseases such as cancer and heart disease and memory disorders. The American FDA should now decide whether this study will be carried out. Professor Dr. med. Dr. H. c. Helmut Schatz, media spokesman for the German Society for Endocrinology, comments: "It would be the first time that the FDA has approved a study on a drug that is not used to prevent, treat or cure a disease." When drugs are used to extend life and delay age-related illnesses, categories change. Professor Schatz points out that aging as an irreversible biological process is turning into a treatable disease.
The study will include up to 3,000 people between the ages of 70 and 80 who already suffer from one of the three diseases that occur more frequently in old age: coronary heart disease, cancer or cognitive disorders (memory, thinking, perception and others Disorders up to dementia). People with diabetes will not be included in the study, as an influence on aging and diseases by influencing the glucose metabolism, as is the case with diabetes patients through metformin, should be excluded. The aim of the study is to find out whether metformin can directly prevent age-associated diseases and postpone death.
The oral antidiabetic drug metformin has been used successfully in the treatment of type 2 diabetes for 60 years. "It is not surprising that metformin, of all things, was selected from among the drugs suspected of having 'anti-aging effects'," says Professor Schatz. There are many indications that the drug from the group of biguanides is not only beneficial for diabetes. The GLINT study is currently investigating prospectively whether it can prevent heart disease or cancer in non-diabetics. Metformin has already been shown to have a positive effect on health and life span in worms and some strains of mice. However, there is also evidence that the use of metformin can sometimes be associated with vitamin B12 deficiency and cognitive impairment.
Resveratrol, which is found in red wine, for example, and rapamycin, which is used to prevent rejection reactions after organ transplants, are also among the substances to which one ascribes a "life extension". A life-extension study with rapamycin is currently underway in dogs. However, a short diet also has a positive effect on the lifespan. "The easiest thing to do is to eat less, that is, to reduce your calorie intake," says the DGE media spokesman.
Even if the idea is tempting to postpone diseases of old age with medication and to prolong life as a whole, the question of the long-term side effects of the substances always remains with "medication against aging". Naturally, this can only be recognized after many years and decades. The media spokesman for the DGE therefore recommends living sensibly, exercising a lot and as outdoors as possible, and staying moderate when eating.

Endocrinology is the study of hormones, metabolism and diseases in this field. Endocrine glands, such as the thyroid or pituitary gland, but also certain cells in the testes and ovaries, release endocrine disrupting hormones, that is to say they are released "inward" into the blood. In contrast to this, "exocrine" glands, such as salivary or sweat glands, release their secretions "to the outside".
