Neue Methode: Menschen werden über Chips in Medikamenten kontrolliert

Neue Methode: Menschen werden über Chips in Medikamenten kontrolliert

Forscher in den USA haben eine neue Methode der Patienten-Überwachung entwickelt: Mikrochips in Tabletten, die auf Verdauungssäfte reagieren, senden Informationen über das Smartphone an die Ärzte. Kritiker sprechen von Big Brother und warnen vor einer Ausweitung der Anwendung. Tatsächlich steckt in der Technik die bisher umfassendste Überwachungs-Möglichkeit der Menschheit.

Die US-amerikanische Food and Drug Administration (FDA) hat erstmals Mikrochips zur oralen Einnahme zugelassen, wie Nature berichtet.
Ein sandkorn-großer Sensor, der in Pillen eingelassen wird, reagiert auf Kontakt mit Verdauungssäften und schickt eine Nachricht an ein Smartphone, auf dem eine entsprechende App installiert ist. So können Ärzte kontrollieren, ob Patienten ihre Medizin ordnungsgemäß einnehmen. Vorerst ist der Einsatz nur für Placebos erlaubt, in Kürze soll aber auch das Okay für verschiedenste Medikamente kommen. Hergestellt werden die Chips vom US-Unternehmen Proteus Digital Health.
„Das halte ich für ein orwell’sches Szenario, das nicht stattfinden darf. Die Kooperation der Patienten bei Behandlungen ist zwar ein internationales Problem, die Erfolgsquote ist aber von Arzt zu Arzt unterschiedlich. Ein Funktionierendes Verhältnis zwischen Arzt und Patient ist das beste Mittel für regelmäßige Medikamenteneinnahme. Werden Menschen beispielsweise auf die Alkoholverträglichkeit eines Medikaments aufmerksam gemacht, ist eine Einnahme am Wochenende wahrscheinlicher”, sagt Otto Pjeta vom Medikamentenreferat der Österreichischen Ärztekammer. Am Ende müsse aber jeder Patient das Recht haben, über seinen Körper zu bestimmen.
In den USA nehmen bis zu 50 Prozent der Patienten ihre Medikamente nicht regelmäßig ein. „In Europa sind die Zahlen vergleichbar. Viele Menschen nehmen verschriebene Medizin entweder gar nicht oder nicht regelmäßig“, sagt Tassilo Korab, Sprecher des Healthcare Compliance Packaging Council Europe, gegenüber pressetext. Der Chip in der Pille könnte solche Probleme beheben. Der winzige Sensor aus Silizium und Spuren von Kupfer und Magnesium reagiert auf Kontakt mit Magensäure und sendet ein Signal, das an den Arzt geht.
Bei Unregelmäßigkeiten können Mediziner einschreiten und die Dosis oder die Gabemethode anpassen. „Ähnliche Ansätze gibt es mit intelligenten Packungen, die Ärzte informieren, wenn eine Tablette entnommen wird. Diese Methoden sind allerdings aufwendig und teuer. Für Einzelfälle, in denen das Leben der Patienten von regelmäßiger Medikamenteneinnahme abhängt – etwa Organtransplantationen – halte ich Überwachung für sinnvoll“, so Korab. Die Chip-Pille sei eine bessere Variante, weil sie die Einnahme tatsächlich garantieren kann. „Auch in schweren Fällen bin ich gegen eine Überwachung, weil sie die Würde der Menschen verletzen würde“, so Pjeta.
„Menschen, deren Leben von einem Medikament anhängt, sind oft dankbar für die Kontrolle. Angst vor Big Brother ist hier deshalb nicht angebracht. Für eine flächendeckende Anwendung macht die Technologie ohnehin keinen Sinn“, so Korab. Bei weniger kritischen Fällen gibt es andere Mittel und Wege die Kooperation der Patienten zu gewährleisten.
„Die Wichtigkeit der Thematik muss Ärzten bereits im Studium beigebracht werden. Derzeit können viele Mediziner das Problem überhaupt nicht richtig einschätzen. Zusätzlich muss den Patienten die Einnahme eines Medikamentes so einfach wie möglich gemacht werden, durch entsprechende Gestaltung von Verpackungen und Beipacktexten. Angaben zu Nebenwirkungen, die dort aus Haftpflichtgründen stehen, haben dort eigentlich nichts zu suchen. Auch ein Kontrollinstrument für die Patienten selber kann helfen“, so Korab.
In den USA setzt die Medizin trotzdem lieber auf die Technik. Einige Experten sehen im verschluckbaren Chip den Anfang einer schönen, neuen Welt. Chips im Körper könnten künftig verschiedenste Daten liefern, mit Minilabors Analysen durchführen und sogar kontrolliert Medikamente verabreichen. „Die 2010er-Jahre werden als dieÄra der digitalen medizinischen Elektronik in die Geschichte eingehen. Es wird gerade an vielen Technologien gearbeitet, die die Medizin verändern werden“, sagt Eric Topol, Autor des Buches „The Creative Destruction of Medicine“.
Angesichts des massiven Missbrauchs von Privat-Daten, wie sie von Google, Facebook, dem BND und der NSA praktiziert werden, ist bei der neuen Technik Vorsicht angebracht.
Zu oft schon wurde der Menschheit versprochen, eine Innovation sei ausschließlich zum Nutzen der Bürger.
Geschäftemacher und Tyrannen finden sind immer.
Und sie werden verwenden, was sie in die Finger bekommen.
In einer schwachen Demokratie, wie wir sie derzeit haben, kann eine smarte Erfindung ganz rasch zur tödlichen Gefahr werden.

Over the Counter Brain Damage: Common ‘Medicines’ that Cause Long Term Cognitive Impairment



Over the Counter Brain Damage: Common ‘Medicines’ that Cause Long Term Cognitive Impairment

JUL 23 • A PARADIGM SHIFTBIG PHARMAHEALTHMEMORY • 2129 VIEWS • COMMENTS

pills-moneyDrugs commonly taken for a variety of common medical conditions negatively affect your brain, causing long term cognitive impairment. These drugs, called anticholinergics, block acetylcholine, a nervous system neurotransmitter.
They include such common over-the-counter brands as Benadryl, Dramamine, Excedrin PM, Nytol, Sominex, Tylenol PM, and Unisom.
Other anticholinergic drugs, such as Paxil, Detrol, Demerol and Elavil are available only by prescription.
Physorg reports:
“Researchers … conducted a six-year observational study, evaluating 1,652 Indianapolis area African-Americans over the age of 70 who had normal cognitive function when the study began … ‘[T]aking one anticholinergic significantly increased an individual’s risk of developing mild cognitive impairment and taking two of these drugs doubled this risk.’”
From Dr. Mercola:
Many view over-the-counter (OTC) drugs as safe because they don’t require a prescription. Well nothing could be further from the truth.
In fact, many OTC drugs were previously carefully monitored prescription drugs. Many people are not aware that while I was in college in the 1970s, I worked as a full time pharmacy apprentice and helped sell drugs to patients all day long.
Motrin was the first non-salicylate prescription NSAID. Now it is a popular OTC ibuprofen option. Similarly, anti-ulcer drugs like Tagamet, Zantec, and Prilosec used to be carefully controlled. Now they can all be easily purchased in a smaller “OTC strength” that nearly doubles the number of pills required to equal the prescription dose.
Just because a drug is available without a prescription does not make it any less dangerous. It is still a chemical, which in no way, shape, or form treats the cause of the problem and can lead to complications that can seriously injure, if not kill, you or someone you love.
So this is clearly important information that can help you or someone you love reduce your risk of dementia as you get older. Based on the findings of this study, I would strongly recommend that seniors in particular avoid all anticholinergic drugs, like Benadryl (generic is diphenhydramine) which is a pervasive and commonly used in virtually all of the OTC sleeping pills.
Researchers will continue studying the matter to see whether anticholinergic-induced cognitive impairment can be reversed, but don’t hold your breath. Avoidance is really the best solution.

What are Anticholinergic Drugs?

Anticholinergic drugs block a nervous system neurotransmitter called acetylcholine. Those suffering from Alzheimer’s disease typically have a marked shortage of acetylcholine.
Anticholinergic drugs are available both over-the-counter and by prescription, as medications used for a variety of symptoms can have this effect. Examples include night-time pain relievers, antihistamines, and other sleep aids, such as:
  • Excedrin PM
  • Tylenol PM
  • Nytol
  • Sominex
  • Unisom
  • Benadryl
  • Dramamine
Prescription drugs with anticholinergic effects include certain antidepressants, medications to control incontinence, and certain narcotic pain relievers.
Examples of prescription meds in these categories include:
  • Paxil
  • Detrol
  • Demerol
  • Elavil

A Special Note for Aspartame ‘Reactors’

Many of the drugs listed here, as well as a long list of additional ones, contain diphenhydramine. As an important side note, you need to beware that chewable tablets and rapidly disintegrating tablets that contain diphenhydramine may be sweetened with aspartame.
If you have the genetic disease phenylketonuria (PKU), you must be particularly careful to avoid these types of drugs and all other types of aspartame-sweetened foods and beverages in order to prevent mental retardation.
But many other people also suffer detrimental health effects from aspartame, so you should know that this is yet another potential source of this toxic sweetener.

Anticholinergic Drugs Increases Dementia in the Elderly

I’ve previously written about the health dangers of many of these individual drugs. Paxil, for example, is an addictive antidepressant that is well known to increase the risk of suicide in children and teens. It is also known to increase violent behavior.
Benadryl and Sominex have previously been found to cause hallucinations in the elderly, and a number of the drugs on the list also promote dental decay.
The results of this study indicate that drugs with anticholinergic effects may be yet another piece of the puzzle that might explain the sharp rise in dementia and cognitive decline.
According to the University of Michigan, dementia strikes about 50 percent of people who reach the age of 85. Of those, about 60 percent go on to develop Alzheimer’s disease.
In this study, the researchers tracked the intake of anticholinergic drugs and monitored the cognitive abilities of 1,652 African-American seniors, aged 70 and older, for six years. All of the participants had normal cognitive function at the outset of the study.
Fifty-three percent of the participants used a ‘possible anticholinergic,’ and 11 percent used a ‘definitive anticholinergic’ drug.
They found that those who took drugs classified as ‘definite anticholinergics’ had a four times higher incidence of cognitive impairment.
In those who were not carriers of the specific gene, APOE ε4 allele, the risk was over seven times higher. (The APOE ε4 gene is known to influence many neurological diseases, and is considered a high risk factor for Alzheimer’s.)
Taking two of these drugs further increased the risk of cognitive impairment.
PhysOrg reports:
“Simply put, we have confirmed that anticholinergics, something as seemingly benign as a medication for inability to get a good night’s sleep or for motion sickness, can cause or worsen cognitive impairment, specifically long-term mild cognitive impairment which involves gradual memory loss.
As a geriatrician I tell my Wishard Healthy Aging Brain Center patients not to take these drugs and I encourage all older adults to talk with their physicians about each and every one of the medications they take,” said Malaz Boustani, M.D., IU School of Medicine associate professor of medicine, Regenstrief Institute investigator and IU Center for Aging Research center scientist.”

Even More Reasons to Ditch the Sleep Meds

In 2008, Americans filled more than 56 million prescriptions for sleeping pills and spent more than $600 million on over-the-counter sleep aids. But anticholinergic sleep medications in particular may be causing far more harm than good, especially long term, without providing any benefit at all.
In a recent article, CBC News reported that the U.S. Food and Drug Administration has had data for 15 years which shows that over-the-counter sleep aids like Tylenol PM and Excedrin PM do not offer any significant benefit to patients.
There’s no explanation for why the FDA took 15 years to evaluate the industry’s research, but upon final analysis “the data suggests the combination products are statistically better than a placebo but not by much,” CBC News reported.
I guess it can be chalked up as yet another vibrant example of how industry research frequently amounts to little more than corporate wishes and good PR fodder.
Another analysis of sleeping pill studies from 2007 (financed by the National Institutes of Health) found that sleeping pills like Ambien, Lunesta, and Sonata reduced the average time to go to sleep by just under 13 minutes compared with fake pills — hardly a major improvement.
Yet, the participants believed they had slept longer, by up to one hour, when taking the pills.
This may actually be a sign of a condition called anterograde amnesia, which causes trouble with forming memories. When people wake up after taking sleeping pills, they may, in fact, simply forget that they had been unable to sleep!
You would be far better off putting your money toward authentic solutions to help you sleep than on sleeping pills, as it’s now clear that they do next to nothing to help you sleep – in fact, they may actually make it more difficult for you to get a good night’s rest naturally – and may significantly increase your risk of dementia.

Sleeping Pills are NOT a Safe Solution for Sleepless Nights

Please understand that resorting to sleep medications is risky business, and that these pills do not address the underlying reasons why you’re having trouble sleeping in the first place.
In addition to the long-term problems already discussed, there are other serious, not to mention bizarre, risks involved.
For starters, these pills are notorious for being addictive, which means that once you want to stop taking them, you’ll likely suffer withdrawal symptoms that could be worse than your initial insomnia. Some, such as Ambien, may also become less effective when taken for longer than two weeks, which means you may find yourself needing ever higher dosages.
Ambien may also make you want to eat while you’re asleep — and I don’t mean sneaking down to grab a piece of fruit. The sleep eating can include bizarre foods such as buttered cigarettes, salt sandwiches, and raw bacon.
Sleeping pills, and again Ambien in particular, are also known to increase your risk of getting into a traffic accident. Ambien actually ranks among the top 10 drugs found in the bloodstreams of impaired drivers, according to some state toxicology labs.
Among the elderly, using sleeping pills may increase the risk of nighttime falls and injuries, and anyone who takes them may find they wake up feeling drowsy if the effects of the drug have not worn off yet.
You’re far better of finding safe and natural solutions that will actually address the underlying causes of your sleepless nights instead of just cover up the resulting symptoms.

How to Get a Good Night’s Sleep Without Dangerous Drugs

If you are having trouble sleeping, please do not ignore the problem or simply wait for it to go away. Quality sleep just as important as your need for food, water, and pure air — and there are very simple methods to help you get yours.
Please read my comprehensive sleep guide 33 Secret’s to a Good Night’s Sleep for my full set of recommendations, but to start, make certain you are exercising regularly.
A Stanford University Medical School study found that after 16 weeks in a moderate-intensity exercise program, subjects were able to fall asleep about 15 minutes earlier and sleep about 45 minutes longer at night. However, don’t exercise too close to bedtime or it may keep you awake.
Stress is another major reason why people have trouble sleeping, which is why I suggest you start to wind down from your day at least an hour before your bedtime (but preferably two or more).
Calming activities such as journaling, meditating, sipping herbal tea, washing your face, using the Emotional Freedom Techniques (EFT) or reading a book may soothe your mind and help you unwind. Be sure your phone, email, and television are all off during this time.
Make sure your sleeping environment is comfortable and conducive to sleep.
This includes keeping the temperature cool, adding in some white noise if you need it and making sure your room is pitch-black. If there is even the tiniest bit of light in the room it can disrupt your circadian rhythm and your pineal gland’s production of melatonin and serotonin. For this reason, I highly recommend adding room-darkening drapes to your bedroom, or if this is not possible wearing an eye mask to block out any stray light.
Again, by following my 33 Secrets for a Good Night’s Sleep, the majority of people will be able to fall asleep and stay asleep. However, for times when sleep is especially difficult, these eight natural remedies may also help and are far safer than sleeping pills of any kind.
