About AD 923

AD 923 is an optimised, sublingual formulation of the strong opioid analgesic fentanyl. It has been specifically designed to provide rapid onset of analgesia in a device that is easy to use by either the patient or their care giver. An additional benefit is the lockout system that prevents inadvertent overdosing. Sosei has concluded a range of studies that confirm the potential of this novel product.

Sosei is currently evaluating its commercialisation options for the un-partnered territories.
