Medication adherence technology firm, Adherium Ltd., has won FDA approval for over-the-counter (OTC) sales of its Smartinhaler sensor for Astrazeneca's Symbicort asthma inhaler. The "jacket-like" device wraps the inhaler and records and shares data on use, timing and overall care plan management to a patient's smartphone and to their physician. While the company partners with the majority of inhaler developers to provide compatible sensor devices, the approval is Adherium's first in OTC.
