Is Pirenzepine available in the united states ? None of the pharmacies seem to know about it. If one could get Pirenzepine from another source does any one know where directions could be found to compound it into a cream ? I found a pharmacy that offered to compound oxybutynin (another drug in the Pirenzepine family) into a trans dermal cream but does anyone think a pharmacies compounded oxybutynin cream would actually work. I'm currently taking the oral version of oxybutynin and it seems to be having a positive effect on my Peripheral neuropathy but oral has a lot more side effects. But I would like to try the trans dermal cream version of Pirenzepine as it would be going directly to the nerve endings in my hands .
Thanks for any and all help on this subject.

You should be looking for Oxytrol. It is a transdermal patch used for bladder spasms. I am trying it right now with interesting results. I have less numbness / improved sensation in numb area of feet, more skin wrinkling in water with my hands ( improvement in autonomic neuropathy), more tingling in neuropathic areas (maybe Tinel's sign for regenerating axons).

It is a bit of a mixed bag though because I still experience stinging pains and the electrical pains. However, I just read a paper that said that these pains occur with regenerating axons because of changes in the number of sodium channels. The issue appears that continuous neuropathic pain is an ongoing regeneration process that never succeeds in fully reinnervating the tissue. Ironically enough the people who just develop numbness without pain have a less healthy peripheral nervous system because no regeneration is going on. They just lose nerves and go totally numb. The people who have pain going on have regeneration happening but the regeneration is overwhelmed by the neuropathic disease process. Some researchers are trying out drugs to turn off the regeneration process to bring relief to people with pain where there is no hope for successful regeneration. Personally, I would be reluctant to use it.

Pirenzepine is an anticholinergic drug which are linked to an increased risk of dementia.

You are correct that anticholernergic drugs have been associated with an increased risk of dementia. I believe though that people need to weigh the risk of dementia against the very rule and pervasive problems that someone with small fiber neuropathy potentially faces. Obviously, there is pain and sensory issues which can be harsh but there is also the very real danger of autonomic neuropathy.

Many people with small fiber neuropathy experience some level of autonomic neuropathy. These range from cardiovascular complaints ( palpitations / arrhythmias, POTS, more generalized higher beat, exercise intolerance, etc.) to gastrointestinal issues ( constipation, diarrhea, gastroparesis, GERD, etc.), to other more miscellaneous issues ( sweating problems, other organ issues). Let me be clear: autonomic neuropathy can kill you. Cardiac Autonomic Neuropathy kills people all the time. Whenever you hear people dying from "complications of diabetes", one of the big ones is cardiac autonomic neuropathy triggering an episode of sudden cardiac death. As for Enteric Neuropathy ( GI neuropathy), constipation and diarrhea are a pain but gastroparesis can really negatively impact health.

If the M1R antagonists ( pirenzepine, oxybutynin, etc.) can trigger small fiber nerve regeneration, regrowing these nerves would have the potential of halting the progression of the neuropathy and reversing these symptoms. On balance, I would take halting the progression and/or reversing the sensory and autonomic neuropathic symptoms of this disease for an increased risk of dementia. In addition, if you get to a good place with your neuropathy, there is no indication that you would need to keep the dosage the same which might ameliorate somewhat the risk of developing dementia. Just my two cents.

Thank you so much for your sensible reply. I had also heard of the dementia risk and I'm more than willing to take the risk because it also might no cause dementia so again thanks for your sensible reply. A doctor had prescribed oxybutynin 5mg oral dosage but at a little over 4 weeks my feet began to swell, I quit for a few days and my swelled feet went down I then tried 1/2 of the 5mg pill but again after a few more weeks my feet again swelled badly. I think trans dermal is suppose to side step some of the swelling while applying the medicine directly to the effected nerves for better repair of the nerves but I would need a trans dermal gel for that. That's why I was asking about trans dermal delivery. Does anyone think trans dermal will sidestep the swelling feet problem? Also I've found an online supplier for pirenzepine but Its hard to trust foreign pharmaceutical suppliers. I'm not so much afraid of the medicine not being the correct medicine as much as I am afraid of them simply taking the money and just not sending anything therefore costing more time in getting relief and I read some where that the closer to the onset of the neuropathy the medicine is applied the better the chances the medicine will work, I don't know if this is true or not. perhaps others here may know more about this. I have used aldaychemist (an india based company) with great success for other needs but they don't carry pirenzepine. It would be of great help if anyone knows of a legit foreign supplier of pirenzepine. Its not on any US banned list or anything so it shouldn't be a problem. And I might mention that towards the end of the 6 to 7 weeks total I used the oxybutynin my fingers started getting a very slight electrical sensation to touch where before there was no sensation at all so I know this stuff does do something. Sorry for the long post but thanks again for an encouraging reply and also thanks for your and everyone else's time in reading this.

Sorry about the above post. I typed it very fast then when I went back to read the actual post I realized I didn't put it in paragraphs or anything. I realized this when I gave myself a headache trying to read my own post.
I found a supplier of Pirenzepine but its for Pirenzepine hydrochloride when most articles written about this subject states Pirenzepine dihydrochloride. Does anyone know if Pirenzepine hydrochloride will work as well as Pirenzepine dihydrochloride? This is the most important info I need to know at the moment.
If the order goes through I will post a link or at least the name of the pharmacy for others to consider as a supplier for themselves. If its allowed to give out that information on this forum
Thanks a ton for all the help so far.

Just curious if you found a supplier happy and if you have tried the pirenzepine.. definitely interested

Trandermal delivery of oxybutynin ends up in your blood stream. The oxybutnin patch is to treat bladder spasms. The only way to treat the spasms is to get the medication into your blood stream. Consequently, the oxybutynin medication can get to areas of your body where there is no direct application of a gel or a patch.

Two other examples of transdermal delivery systems are smoking patches (to deliver nicotine) and the contraceptive patch ( to deliver contraceptive medication).

Hi Beatle,

When searching for side effects about Pirenzepine i didnt find anything that would indicate that Perenzepine would cause Dementia.This is very serious issue

I know a girl on one of the facebook neuropathy groups that is using this for atleast more then a year and she claims that it helped her to heal for 80% she only has numbness at the moment.

So please provide me with this information

I know it's only been a short time since this comment but do you still think the oxytrol transdermal patch is working for you?
