Summary:  Could an experimental anti-aging cocktail of rapamycin and metformin and other drugs extend life? A Chicago physician is treating patients with an untested anti-aging drug regimen. This article details which medications the doctor prescribes and why he prescribes them.

A Chicago physician has been treating patients with an experimental anti-aging cocktail of rapamycin and metformin as well as other lifespan-extending drugs in a bid to slow down the aging process. Also included in the doctor’s life-extension regimen are a prescription for physical activity and mild calorie restriction.

The doctor’s anti-aging cocktail is composed of medications available at the local pharmacy, drugs that are already FDA-approved for other uses. The physicians cocktail of lifespan-extending drugs includes rapamycin, metformin, statins, aspirin and angiotensin II disruptors.

Anti-Aging Drug Cocktail

Anti-aging drugs are still in the process of being fully vetted. The FDA does not approve aging as a treatable disease.

Statins, aspirin and blood pressure medications are already approved by the FDA to treat heart disease. The drugs metformin and rapamycin are not yet approved to treat aging and are currently in clinical trials to test their life-extension powers.

One U.S. doctor isn’t waiting for the results of those trials.

Alan S. Green, M.D., a Chicago physician has begun prescribing a cocktail of anti-aging drugs to his patients. According to his website, starting in January 2016, Dr. Green began taking rapamycin personally. In a bid to ward off the ravages of aging, Dr. Green takes the medication along with other drugs already available at the local drugstore.

Anti-Aging Cocktail Components

Dr. Green’s prescription for slowing down the aging process include caloric restriction, exercise and a cocktail of anti-aging drugs. In addition to intermittent rapamycin, Dr. Green’s anti-aging drug regimen includes aspirin, metformin, and a standard blood pressure medicine.

Anti-Aging Cocktail Includes Rapamycin

Rapamycin is the world’s most promising life-extension drug. The powerful immune suppressant is already used in transplant patients to prevent them from rejecting donor organs. Scientists believe the drug blocks the key aging pathway shared by all animals. The drug has extended the lifespan of every animal tested so far, from yeast to mice to monkeys. In a well-publicized experiment, rapamycin increased the average life span of middle-aged mice by about a third.

Intermittent Rapamycin Dosing

Dr. Green started taking 6mg of rapamycin, once a week, in a therapeutic practice called intermittent rapamycin dosing. For comparison organ transplant patients typically take 1 mg every 12 hours of a form of rapamycin called everolimus.  While Dr. Green takes about half the transplant dosage of 14mg/week, the Chicago physician’s strategy is to avoid side effects by pursuing an intermittent dosing schedule.

Intermittent rapamycin dosing has been shown to reduce side effects in humans and to extend the lifespan of mice. According to Dr. Green:

“In my practice, I consider the proper anti-aging dose of rapamycin [e.g. sirolimus or everolimus] to be 2-6 mg, and the proper interval 1-3 weeks.”

There is growing evidence to support the life-extending effects of once a week dosing with rapamycin. A related report describes the evidence behind low-dose intermittent rapamycin therapy.

Statin Component

The Chicago anti-aging physician prescribes statins in his anti-aging cocktail. One of the side effects of rapamycin is that it induces high cholesterol, a condition known as hyperlipidemia. According to the doctor, the statins used are used to counteract the side effect of rapamycin.

Physicians use statins to treat high cholesterol. Also known as HMG-CoA reductase inhibitors, researchers have found that statins reduce cardiovascular disease and mortality in high-risk patients. The evidence is strong that statins effectively treat heart disease in the early stages, in what is known as secondary prevention. Additionally, in what is known as primary prevention, researchers have shown that statins benefit people who are at elevated risk for cardiovascular disease but don’t yet have it.

Furthermore, researchers believe that statins have lifespan-extending effects that extend beyond their cholesterol-lowering abilities. Medical science has yet to prove these drugs are useful for life-extension purposes beyond their cholesterol-lowering abilities.

Metformin in The Anti-Aging Cocktail

Physicians use the drug metformin to treat type 2 diabetes. Researchers have found that the drug has remarkable anti-aging powers in this group.

Dr. Green uses metformin in the anti-aging cocktail for two reasons. First of all, the anti-aging research community believes that metformin is a life-extension drug, as it has been shown to prevent cancer and extend the lifespan of type 2 diabetics. The second reason is that metformin counteracts the glucose-raising side effect of rapamycin.

Additionally, researchers have shown that metformin prevents type 2 diabetes in prediabetics. A decades-long track record and hundreds of research studies back the usefulness and safety of metformin in type 2 diabetics.

Testing Metformin in Healthy Seniors

As the linked article shows, researchers are currently conducting a clinical trial to test metformin’s anti-aging powers in healthy seniors. The American Federation for Aging Research (AFAR) is spending sixty-five million dollars on a clinical trial called Treating Aging with Metformin in the Elderly (TAME).

Aspirin Component

Dr. Green adds aspirin for its ability to prevent cancer and heart disease.  As a rationale, the doctor cites the recommendation of the US Preventive Services Task Force (USPSTF), which recommends low-dose aspirin therapy for certain older adults to prevent colorectal cancer and cardiovascular disease.

Angiotensin II Component

The Chicago doctor uses angiotensin II disruptors in his anti-aging cocktail. He recommends them for their blood pressure-lowering powers as well as their potential life-extending capabilities

Angiotensin II drugs are blood pressure-lowering medications. As is the case with statins, these drugs are suspected to have life-extension effects that extend beyond their blood pressure-lowering abilities. Medical science has yet to prove that these drugs are effective for life-extension purposes beyond their blood-pressure-lowering capabilities. According to Dr. Green:

“Disruption of angiotensin II prolongs the lifespan of mammals.”

Doctors commonly prescribe angiotensin II disruptors as blood pressure medications. These medicines decrease the rate of Angiotensin II production. This class of medicines includes angiotensin-converting enzyme inhibitors (ACEI), such as lisinopril and enalapril; and angiotensin II receptor blockers (ARB), such as losartan and candesartan.

Anti-Aging Cocktail Includes Calorie Restriction

Dr. Green also recommends a form of caloric restriction as part of his anti-aging cocktail. Calorie restriction (CR) is the practice of drastically slashing calorie intake to improve health and retard aging. While it sounds unpleasant, a growing body of research suggests the practice fights disease and years to a person’s life.

Practitioners define calorie restriction as a 20% to 30% reduction in calories, along with sufficient quantities of vitamins, minerals, and other essential nutrients.  A typical healthy diet consists of 2000 daily calories for women and 2500 for men.

The Chicago physician doesn’t advocate strict caloric restriction. He merely advises that his patients slim down through diet and exercise. After reaching a healthy weight, the doctor recommends patients consume 8% fewer calories than they need. To back up his recommendations, the physician quotes an observational study of the effects of calorie restriction on the Japanese island of Okinawa during the years 1950 to 1995. Dr. Green says:

“Studies calculated that they [Okinawans] took in 8% less calories than their requirements. They had a remarkable decrease in age-related disease.”

The Okinawan calorie restriction was unintentional. The devastation of World War II brought about a food shortage. While the aftermath of the war created hardships for the Okinawans, the calorie restriction produced remarkable health effects, as Dr. Green said:

“As regards average life span, it was 5 years longer than Americans.”

Exercise Part of Anti-Aging Cocktail

The Chicago physician also includes physical activity in his anti-aging cocktail. Studies show that regular exercise improves health and reduces the risk of developing diseases like type 2 diabetes, cancer, and cardiovascular disease. Physical activity enhances the quality of life and provides both immediate and long-term health benefits.

Criticisms of Green’s Anti-Aging Cocktail

Criticisms of the doctor’s anti-aging cocktail fall into two categories. The first criticism is that the physician is losing the opportunity to collect valuable scientific data. The second is that the doctor is testing too many interventions simultaneously.

Missed Opportunity

Critics say that the doctor is missing an opportunity to advance medical science. The physician’s intent is to treat patients, rather than run an experiment. Hopefully, the doctor is collecting data in a way that will be useful to the field of anti-aging medicine. Researchers are interested in knowing the long-term effects of this anti-aging cocktail.

Many Simultaneous Therapies

A second criticism of the physician’s anti-aging cocktail is that the doctor is testing too many interventions at the same time. If Dr. Green’s patients live longer, which part of his anti-aging cocktail is responsible? Was it the calorie restriction, the anti-aging drugs, the exercise or a combination?

Hopefully, Dr. Green is collecting patient data systematically, in a way that can be useful to the scientific community. The data could tell us if this particular combination of life-extension interventions is helpful or harmful to health.

Other Groups Taking Anti-Aging Cocktails

Dr. Green’s patients aren’t the only ones taking anti-aging cocktails. A growing community of anti-aging enthusiasts takes life-extending drugs in a bid to hold back the ravages of aging. Google futurist Ray Kurzweil takes 100 pills daily. Like Dr. Green’s drug regimen, the Google futurist’s anti-aging cocktail also includes statins and metformin.

An entire anti-aging industry has sprung up to serve the needs of life-extension enthusiasts. Google invested 1.5 billion dollars on startup Calico, a company tailored to developing life-extension therapies.

Take Home Message

  • A U.S. doctor is prescribing an experimental anti-aging drug cocktail that includes the anti-aging drugs metformin, statins, rapamycin, aspirin and blood pressure medications.
  • In addition to the anti-aging drug cocktail, the Chicago physician also recommends calorie restriction and exercise.
  • At least two of the drugs in the cocktail has not yet been fully vetted for anti-aging purposes.
  • Rapamycin has not been thoroughly tested as an anti-aging drug. Researchers are currently testing the drug for this purpose in clinical trials.
