PEDMARK helps protect a person’s hearing from the risk of cisplatin-related hearing loss. This kind of hearing loss happens when cisplatin builds up in the cochlea (the part of the inner ear shaped like a spiral).

Cisplatin destroys the tiny hairs in the cochlea that mainly control hearing. Once these hairs are destroyed, they do not grow back. That means that any hearing loss lasts forever.

How PEDMARK works

It isn’t known exactly how PEDMARK works, but scientists think it may:

  • Help the body make antioxidants that fight the harmful build-up caused by cisplatin
  • Neutralize the harmful substances made by cisplatin molecules
  • Attach to the cisplatin molecules to reduce the amount of harmful substances they release

There’s no substitute for PEDMARK
