I used 4-AP off and on @ 1 yr ago; it seemed to work ok. (2x campath & worsening of symptons right after both, then 3mo short of 2nd annual infusion recurrance of new symptoms w/ lasting damage but no MRI negative change, in case you forgot
4ap is available through compounding pharmacy, and has been around for a LONG time. lots of data in spinal cord injury. so the thing w/ 4 AP is that, being compounded, there can be a wide variety of variables, so each batch theoretically could be a lil different. when i changed pharmacies, i had bad side effects and never tried it again. the first pharmacy, i didnt have side effects and had mild improvement; but it only lasts 4 hours. literally: 240 minutes. then bam, its gone. you don't feel anything from the drug, just notice a little easier or stronger to move around.
so the benefit of (accordia's?) fampridine is 1) sustained release & 2) unified formulation. the downside is the price will rise exponentially. right now i pay $90 for 1 month supply, no insurance coverage. maybe it would be better w/ insurance and a low copay but i'm sure they'll charge insurance a crapload, thereby making everything cost more all together. that's the US healthcare strategy.....my soapbox??
so stay strong! stay hopeful! you are science-in-the-making and blogging so we can read about your experiences play by play, instead of reading a boring journal publication with no names or faces to the data. thank you for sharing! best of luck! don't forget the simple things like diet & exercise...
