Disufenton/acetylcysteine (also known as HPN-07/NAC, NHPN-1010, or NXY-059/NAC) is an investigational combination therapy consisting of the nitrone free-radical trap disufenton sodium and the antioxidant N-acetylcysteine (NAC). It has been studied in preclinical research for noise-induced sensorineural hearing loss, tinnitus, cochlear synaptopathy, and traumatic brain injury, although as of 2024 there is no reported clinical development for any indication.[1]
Disufenton/acetylcysteine is described as acting through free-radical inhibition and oxygen-radical scavenging, processes relevant to oxidative stress injury in auditory and neural tissues.[2]
Rationale in auditory disorders
Oxidative stress and neuroinflammation contribute to noise induced cochlear injury, ribbon-synapse loss, and tinnitus-related neuronal hyperactivity.[3]
