“New pill capsules that send a message to a smartphone as they move through the GI tract have emerged as a way to track whether patients are taking their medicine as prescribed. The problem of nonadherence to medication instructions causes about 125,000 deaths a year and at least 10 percent of hospitalizations, according to one estimate.
Soon the ingestible tracking technology could also be used to make sure patients aren’t taking too many of drugs like opioids, which are highly addictive. Researchers at one Boston hospital think the high-tech pills could help physicians prescribe the right amount of opioids, helping patients avoid taking more than they need.”
