We've entered the era where medicine is going into full sci-fi mode in the quest for better diagnostic and treatment tools.
The New York Times reports
A couple of year ago, Phillips came out with an intelligent pill. The so-called "iPill" contained a microprocessor in it that could release medication at a specific spot in the GI tract. The goal was to eliminate the "chemo phenomenon," where you make a person's whole body sick just to target illness in one part of the body.
The iPill contains a wireless transmitter that senses acidity and body temperature to determine where to pinpoint the medication. Some of its expected uses will be for colon cancer treatment and GI tract disorders -- if Phillips can convince the pharmaceutical companies to buy into the technology.
The San Francisco Chronicle ran a simple explanation of the iPill a couple years ago. The real shocker so far is that the cost is $1,000 per pill. Once it's in mass production, however, that price would come down to about $10 per pill. Talk about the economy of scale!
