I was told by the head medical doctor that ventoline is not accepted. The norwegian CAA draw the line between "Bronchodilators" that relieves symptoms (like ventoline), and Anti-inflammatory Drugs, that prevent symptoms.
They might be a bit on the strict side though.. As one of the docs told me they had an issue some years ago where a guy got the class 1, did the CPL/ATPL, only to be rejected somewhere abroad on first renewal. The guy sued them and it got ugly.
So do keep in mind the risk of getting worse and have your medical rejected later on.
