Thread: How many people have tried or take 4-aminopyridine?

  1. #1

    How many people have tried or take 4-aminopyridine?

    4-aminopyridine (4-AP) is a drug that is taken orally and has been shown to improve function of axons that have been demyelinated. Since the early 1990's, the drug has been available by prescription from compounding pharmacies. Several clinical trials have suggested that the drug improves function in people with multiple sclerosis (MS) and spinal cord injury (SCI). As many as 10,000 people in the United States are reputed to be taking the drug. For people who have SCI (from any cause) or MS, which category do you belong in?

    How about this question:

    If you have never taken 4AP, are you waiting for the Phase 3 trial and FDA approval?

    egroman, thanks. I wish that I had room for that question... I also wanted to put in the option: "You are not interested". But both that option and yours would be covered by "You have never taken 4-AP".

    The most important option, however, is "You are now taking 4-AP".

    Incidentally, the phase 3 trial has been approved by the FDA and should be starting imminently. They just had their investigator meeting and things are moving along briskly. Keep tabs of the situation at and you can sign up for email notification through that site.

    I wanted to ask you Dr. Young... have you heard anything about when Acorda will start the recruting? I'm (as you know by now) very unpatient and haver checked out the college pharmacy which, if i don't qualify for the trials, would be my next step.
    Any info would be appreciated since my doc can't prescribe meds that r not FDA approved

    Acorda just held their investigator meeting in Florida and they should be returning home and getting set to start the trial as soon as they are ready. I have been anticipating a go signal shortly and will post it on the site as soon as I know.

    Thanks Dr. Young.

    I didn't know Acorda had plans of starting with chronic injuries this year. Everytime I see a post that has something to do with 4-AP I normally overlook it since I knew the criteria was originally for incompletes. Where in Florida may I find info on participating in the study?

    I just followed your link and requested the info from acorda, but if you have the info available that would be great too.

    I am bumping this poll up to see if we can get more people to respond. If you have SCI, even if you have not heard of 4-AP, can you respond? I think that it would be very interesting to know what proportion of our community have taken or are now taking 4-AP.

    Over a third of people who have responded have indicated that they have tried 4-AP. Is this true, base do your conversations with other people with spinal cord injury? Wise.

    I tried it slowly ramping and once I was able to work out on the recumbent bike far better than ever before, even had heavy ankle weights on, but then it didn't help noticebly after that, except I seemed to have worse stress incontinence. I was on the list to participate in Madonna Rehab Hospital's clinical trial for FampridineSR, but they made the excuse they hadn't the time to get ready for it though they had enough participants. They've never helped me before and didn't surprise me.

    In my area I think about half the incompletes I've talked to have tried 4-AP. I think this has to do with more doctors in the Baltimore-Washington corridor being familiar with several of the MS Centers and their use of it. That and the number of patient computer users with all libraries being hooked up to the internet and ready access of doctors to NIH and clinical trial information.

    I'd also guess that maybe 10% of completes have tried 4-AP and the same ratio of those with Cauda Equina injuries trying 3,4 DAP.
