From the Daily Herald online…
How does the smart PrEP work?
“The pill Truvada — the only PrEP drug approved by the Food and Drug Administration — has a sensor tablet encapsulated over it, so that when the pill is swallowed, the sensor tablet comes in contact with gastric fluid in the stomach and creates an electrical signal,” explained Dr. Gregory Huhn, CCHHS’ Associate Professor of Infectious Diseases and principal investigator of the trial. “The electrical signal is less than the frequency of a heartbeat, so nobody is going to feel it. But it transmits a signal in real-time that the pill has been ingested.”
By having a record of when the pill has been taken that goes to both the patient and his or her doctors or providers, the providers can reach out to patients who haven’t been taking the pills as directed and find out if there are any issues they can help resolve-like medication side effects a patient might be having or that they’ve run out of medication, Brothers said.
PrEP is supposed to be taken once a day.
