US approves first pill with digital tracking device

US regulators have approved the first pill that contains a digital tracking sensor to alert doctors and caregivers as to whether a patient is taking the medication as scheduled.

The pill, called Abilify MyCite (aripiprazole tablets with sensor), is designed for patients with schizophrenia, bipolar disorder and depression, according to the US Food and Drug Administration.

A patient ingests the pill, and a sensor inside the pill activates when it reaches the stomach fluids, sending a message to a wearable patch.
