Remote-Controlled Pills Do the Trick
A remote controlled pill has been invented by the electronics company, Philips, which can carry medicine in a cavity that is opened by a remote signal. MRI and ultrasound is used to track the pill and when the pill reached the desired site the medicine in released through an electronic trigger.

The passage of the pill can be tracked with the help of MRI or ultrasound. As soon as the pill reaches the appropriate location, the medicine in it can be released through an electronic trigger.

The company hopes to make the pills cheap enough to be disposable so that they do not require recollecting and recycling after use, reports New Scientist magazine.

Currently, pharmacists use various mechanisms to control the release of drugs from a pill. Many times the pills have a coating that is designed to be dissolved in a particular part of the digestive tract or after a certain amount of time.

However, this does not always work since the rate of passage through the body can vary, and some individuals have higher levels of digestive enzymes than others.

Philips' invention is expected to solve this problem.
