> Diuretics affect the way the body metabolizes and excretes beta-2 agonists. If you are on a diuretic medication (or on any other substance in the S5 category of the Prohibited List) for any reason and you are using an inhaler that contains salbutamol (albuterol) or formoterol, then you may need a TUE. Please see the TUE section below.
Edit: if you’re about to talk about how it affected the ruling for the asthma medication, then you’re just repeating the article and should just read that instead of arguing in the comments.
The reason why is actually in the article but I’m sick of just typing it out for you when you can stop being lazy and read the thing yourself.
It’s a real tough choice.
Which is covered in the article.
And one of the main points of this article is that the rules are inconsistent and not based in reality.
To paraphrase the article (but don't take my word for it, I highly suggest reading it yourself), the rules are fatally flawed because of the bimodality where contaminants at arbitrary concentrations determine whether other medications in urine samples are allowed or not.
