Posted by windsorchris @windsorchris, Aug 1, 2021

Stage 2 Trials were scheduled to end in July. Does anyone have any information on results?

Interested in more discussions like this? Go to the Neuropathy Support Group.

Please share how you got the Pirenzepine....otherwise it is a teaser for those of us who would like relief. Thank you. I am grateful every day for this site and the sharing of information.

Thanks. And I would like to add that though WinSanTor's studies have focused primarily on diabetic peripheral neuropathy their researchers have indicated that the drug will likely also have benefits in several other forms of PN, including chemotherapy induced PN, though this remains to be demonstrated. At some point I will comment on my personal experience with "scrambler therapy" in Rome last summer and with my ongoing use of red light therapy and carboxy therapy.
