Pharmacy On-a-chip Dispenses Drugs Automatically 74

Posted by samzenpus from the time-for-your-medicine dept.
An anonymous reader writes "The idea is simple — load up a microchip with a whole pharmacy of drugs that are dispensed as needed automatically. The devil has been in the details, since mistakes could kill the patient if, say, a leak developed dumping dangerous cocktails into the bloodstream. This MIT sponsored company, however, claims to have perfected wireless control of a pharmacy-on-a-chip and has just completed the clinical trials to prove it. The test microchip has just 20 doses of a single drug, but their new prototype will house thousands of pin-prick sized drug reservoirs, after which they will seek FDA approval. The elderly (who have complicated drug regime) and soldiers could both benefit from these smart pharmacies-on-a-chip, since drugs can be dispensed even if the patient is unconscious."

    From TFA:
    "This avoids the compliance issue completely, and points to a future where you have fully automated drug regimens."

    I say this jokingly now, but first they will start using it on psychotic people who will not self administer. Then.... who knows.

      Of course, the practical limit here is just how much drug can be stored in one. Very few drugs work at even the microgram level. If you take three drugs at 20 mg/day each, that's over a gram in two and a half weeks. A three-month supply will need five grams of drugs - at which point you're talking about a pretty substantial implant.
      • And that's also ignoring the fundamental inefficiency of having a great many drugs on each chip, which will never be used. If there's 100 drugs on a chip, and only 10 drugs get dispensed by one chip, then that's wasting 90% of globally available drug reserves.

          So much better for the drug companies. But you don't have to load it up with that many drugs. By filling it to capacity with just the drugs you need, you'd lengthen your time between refills.

          But then, filling is the big problem. How do you guarantee that all those little reservoirs have the right drugs in them?

      • That depends on the bioavailability of the drug in question.

        See http://en.wikipedia.org/wiki/Bioavailability [wikipedia.org]

        Most of the drugs you get are mostly filler / carrier mediums. Internally, you can just have the pure drug itself, reducing the required dosage.

        What I don't see is a easy way to package multiple drugs on a single implant without custom making each implant which I think is cost prohibitive. Standardized cocktails would be a different story.

          I'm surprised they didn't go with some sort of tiny metering system such as with a plunger and miniature stepper motor. That way it could be refillable (syringe) without having to cut the patient open every so often to replace the unit.

          Depends on the likelihood of the various failure modes, surely? The simple system on a chip which they're talking about should be easier to make robust than something with complex pumps and moving parts. (To say nothing of the complexity of working with microfluidics; viscosity is a major problem as you scale down...)

      I know that the 'slippery slope' argument is a Slashdot staple, but really?

      Automated drug regimens would be a boon to many people who now for one reason or another forget/skip/whatever. Psychosis, dementia, Alzheimer, ADD, brain damage, the list is long and distinguished.

      Having been around a few people who tend to forget their medication, this would be a substantial improvement in their quality of life and that of the people around them.

      • Great point, but it's a slippery slope. That slope doesn't exist in a vacuum. If you pay any attention at all at what is going on around you, then you necessarily have to be concerned about where this is likely to go. It is all very well to take a positive attitude and say: Hey, this nuclear reaction stuff is great! Think of the possibilities for making a better life for mankind!, but to do so without also remembering Hiroshima is foolish at best.

      • You're talking about type 2 diabetes, which is a problem but almost never quickly results in an immediately life-threatening state. Type 1 diabetes can and does, but it's a much more difficult disease to manage.

          What's more Type 2 does not normally need insulin and can often be treated by tablets that stimulate the pancreas as well as diet and exercise (less fats and raw sugars mean less problem, exercise assists what insulin the body does make).

          Type 1 the body simply stops making insulin and you need to inject it (stomach destroys it so no tablets). There are currently machines that do subcutaneous infusions, and will measure blood sugar levels. There do not seem to be any (in my search) which work like the pancre

      • It is interesting that you think that what people eat, how much they exercise and whether they walk or drive is not dependent on personal choice but on the work of "social engineers". If that really is the case then that is a far bigger problem than diabetes.

        I have 3 family members that are doctors, and diabetic patients (of the Type-II sort) form their most frustrating class of patients. Patient compliance is terrible when it comes to that disease, as the changes are purely lifestyle and the patients just don't want to give up their sugar or exercise. It absolutely drives my family members nuts, as they talk about how these people are killing themselves, and they just can't convince them to do anything about it. Even worse are pe

        i realize diabetes is often genetic. but often its lifestyle based. and that lifestyle is not the result of 'free choice', its the result of urban planners and social engineers who believe in profit over everything else.

        So first of all this only considers type 2 diabetes. Type 1 diabetes is a completely different beast with similar results in blood sugar. So you still will end up with type 1 diabetics that require insulin to eat any carbohydrates. It also should be known that when you are getting low in blood sugar it is food you need, not insulin. It is cases like this where I wish the two types were actually called different diseases. Ah well, not much one can do about it at this point.

    I was once told that even with medication in pill form, roughly 1/3 of prescriptions are never filled and another 1/3 are filled but the patient never takes them.

    As the article states, getting a patient to take drugs which require daily (or multiple times per day) injections is very difficult. For obvious reasons people just don't want to stick themselves with needles, elderly patients forget, some drugs need to be given so frequently the patient has to be wakened every couple of hours, etc.
