I’d like to share experiences of taking this drug, particularly from parkies like myself, who have the 'spelling mistake; on the GBA gene. I hope to be part of the trial of ambroxol, but this seems to be delayed indefinitely, and meanwhile I’m not getting any younger!

A few weeks ago, I started taking a low dosage of ambroxol - 30mg - every evening. I bought it from Amazon under the trade name ‘Brontex’. I chose late evening to take it, because I take my last dose of prescribed meds at 7.30 p.m. and I wanted as much space as possible between the prescribed and unprescribed, so that it would be easier to detect any negative side effects,
Since Brontex is sold as a decongestant, it was hardly surprising that it has greatly reduced the amount of cattarh I get when I wake up in the morning.

I have heard on the grape=vine, that a number of parkies similarly frustrated by the delay in the trial, are taking either 30mg or 60mg. If you are one of them, I’d be interested in your experience.

Hi Jane_L,
have you looked at website The study is called ASPRO-PD.

I’ve looked at it. It doesn’t tell me anything I didn’t already know.

Hi Jane_L

it was the exclusion criteria that caught my eye.


There aren’t any exclusion criteria on the list I’m looking at. Can you give your link again please?

Sorry, I got there in the end. Not only is taking ambroxol a no-no, but so is dbs, which rules me out. Nobody has pointed this out to me before and my immediate response is to feel rather let down.
