Thank you for your reply.
In my reseach, I've found two other drugs for treatment of dry mouth from radiation. Frankly, I'm not sure what they are. They may be gene therapy. Have you heard of either of these?

TEMPOL: This is an antioxident. I found research reports going back to 1994 and as recent as 208. They seem positive for some protection of salivary glands, but I'm wondering if it has been approved?

Second is a patent pending "method". Abstract: Methods are described for using an arginine depleting agent such as arginase and drivatives....protecton of normal tissues in cancer patients underdoing raditherapy...
Don't know the name of the "method." Patent title: Method and Composition for Protection Against Radiation. Inventor: Ning Man Cheng. USPC Class: 424 946. IPC8 Class: AA61K3846FI. I was just wondering what this is, and has it received it's patent.
Does anyone know how to research this. The Patent Office search has confused me.

Thanks
