United Therapeutics announced that the Food and Drug Administration (FDA) has approved TD-300/A, a new inhalation device for use with Tyvaso (treprostinil) inhalation solution. 

Tyvaso, a prostacyclin vasodilator, was initially approved in 2009 for the treatment of pulmonary arterial hypertension (PAH) WHO Group 1 to improve exercise ability. The approval was for a drug-device combination product consisting of Tyvaso plus an ultrasonic nebulizer and accessories.

The new device, TD-300/A, features a more ergonomic design with a single-button operation, an intuitive user interface to adjust breath counts, an internal, rechargeable battery, and a color graphical display that guides patients through the inhalation process and shows the time since last treatment. 

"The launch [...] will further optimize Tyvaso therapy for patients and, we believe, reduce the rate of therapy discontinuation associated with the current nebulizer." TD-300/A is anticipated to launch in the middle of 2018.
