Smartwatch Tracks Levels of Medication in the Body for Personalized Dosing

Researchers at the UCLA Samueli College of Engineering and the Stanford College of Drugs have developed a smartwatch that makes use of electrochemical evaluation to trace ranges of a drug in the physique by analyzing a affected person’s sweat. The system might assist with discovering the appropriate drug and dose for a given affected person in order to maximise therapeutic potential and keep away from side-effects.

At current, most medicine are prescribed based mostly on normal pointers and will be tailor-made based mostly on parameters similar to age and weight, however this not often consists of any further personalization. Nonetheless, there are dramatic variations in how individuals reply to totally different medicine. A big half of this distinction is all the way down to how a lot of a drug is current in the circulation over time, with inter-individual variations in pharmacokinetics being accountable.

For sure medicine, clinicians use repeated blood attracts and lab evaluation to maintain monitor of their ranges in the blood. Nonetheless, that is time consuming, costly, and inconvenient for sufferers. These researchers wished to develop a wearable smartwatch that might present steady real-time measurement of drug ranges in the sweat. Sweat can act as a proxy for the blood, and for many medicine, ranges in the sweat and the blood are very related.

“We wanted to create a wearable technology that can track the profile of medication inside the body continuously and non-invasively,” mentioned Sam Emaminejad, a researcher concerned in the examine. “This way, we can tailor the optimal dosage and timing of the intake for each individual. And using this personalization approach, we can improve the efficacy of the therapeutic treatments.”

The watch works by stimulating sweat glands in the underlying pores and skin via an electrical present. The machine can then analyze the sweat and may establish the electrochemical signature of particular medicine utilizing a voltammetric sensing interface. The result’s real-time steady measurement of drug ranges.

“This technology is a game-changer and a significant step forward for realizing personalized medicine,” mentioned Ronald W. Davis, one other researcher concerned in the examine. “Emerging pharmacogenomic solutions, which allow us to select drugs based on the genetic makeup of individuals, have already shown to be useful in improving the efficacy of treatments. So, in combination with our wearable solution, which helps us to optimize the drug dosages for each individual, we can now truly personalize our approaches to pharmacotherapy.”
