The Food and Drug Administration has approved the first digital pill for the US which tracks if patients have taken their medication. The pill called Abilify MyCite, is fitted with a tiny ingestible sensor that communicates with a patch worn by the patient — the patch then transmits medication data to a smartphone app which the patient can voluntarily upload to a database for their doctor and other authorized persons to see. Abilify is a drug that treats schizophrenia, bipolar disorder, and is an add-on treatment for depression.
The Abilify MyCite features a sensor the size of a grain of sand made of silicon, copper, and magnesium. An electrical signal is activated when the sensor comes into contact with stomach acid — the sensor then passes through the body naturally. A patch the patient wears on their left rib cage receives the signal several minutes after the pill is ingested. The patch then sends data like the time the pill was taken and the dosage to a smartphone app over Bluetooth, and must be replaced every seven days. The patient’s doctor and up to four other people chosen by the patient, including family members, can access the information. The patient can revoke access at any time.
The pill comes after years of research and is a venture between Japanese pharmaceutical company Otsuka and digital medicine service Proteus Digital Health, which makes the sensor. The pill is one way to address the prevalent problem of patients not taking their medication correctly, with the IMS Institute estimating that the improper and unnecessary use of medicine cost the US healthcare sector over $200 billion in 2012. The approval also opens the door for pills that are used for other conditions beyond mental health to be digitized.
Experts though, have expressed concerns over what the pill might mean for privacy. Some are worried that tracking pills will be a step towards punishing patients who don’t comply. Ameet Sarpatwari, an instructor in medicine at Harvard Medical School told The New York Times the digital pill “has the potential to improve public health. [But] if used improperly, it could foster more mistrust instead of trust.”
The Wall Street Journal reports that the FDA is anticipating a potential raft of approval requests for other digital pills. A spokesperson told the publication the FDA is planning to hire more staff with “deep understanding” of software development in relation to medical devices, and engage with entrepreneurs on new guidelines.
