FDA approves first sensor-enabled inhaler


Asthma patients may soon treat themselves with first-ever digital maintenance inhaler.

FDA approved Teva Pharmaceutical’s AirDuo Digihaler (fluticasone propionate 113 μ and salmeterol 14 μ) Inhalation Powder, a combination therapy digital inhaler with built-in sensors that connects to a companion mobile application to provide information on inhaler use to people with asthma. 

AirDuo Digihaler has the ability to not only track inhaler uses, but also measures inspiratory flow rates. This product differs from an add-on that is applied to the top of the device as the technology is integrated into the inhaler, according to Teva.

The inhaler is not meant to be used as a rescue inhaler, according to the company

AirDuo Digihaler has built-in sensors that detect when the inhaler is used and measure inspiratory flow rates. This inhaler-use data is then sent to a companion mobile app using Bluetooth Wireless Technology so patients can review their data over time, and if desired, share it with their healthcare providers. In addition, the device sends reminders to patients’ smartphones to take their medication in accordance with their treatment plan.

The companion app will be available in the Apple App Store and Google Play. Once the app has been downloaded, patients will open it and scan the QR code on top of the inhaler to pair, using the camera on their smartphone. Patients can pair up to 5 Digihaler inhalers to the app. It’s also important to note that AirDuo Digihaler will still deliver medication even if it is not actively connected to the app and if the inhaler and smartphone are not within range of one another, according to Teva.

Even with advancements in respiratory care, research indicates that 70% to 90% of patients are still not using their inhalers correctly, and despite their best efforts, patients may not always follow their treatment plan, and some have difficulty using their inhalers, according to Teva.

With AirDuo Digihaler, patients can receive reminder notifications from the app to take their medication in accordance with their treatment plan, and the app will notify them if their inhalation technique may need improvement so they can share this information with their physician. Digitally connected devices like AirDuo Digihaler provide patients and/or their caregivers with data about their inhaler use and frequency, which may help inform conversations with their physicians regarding inhaler technique and adherence to these medications, which may impact overall cost of care.

Teva is having ongoing conversations regarding access for both AirDuo Digihaler andProAir Digihaler, which was approved back in December 2018. Although the pharma maker cannot disclose details at this time, the goal in collaborating with payers is to focus on the value for both patients and payers.
