There was an asthma medication that worked well for me.
It was based on sodium cromoglycate / cromolyn / CAS 15826-37-6.
King Pharmaceuticals stopped selling their inhalable mixes of it for the western markets.
The brand name was Intal.
It appears to have gone out of fashion. I read that a Scandinavian didn't like it.
Base chemical looks to be still manufactured in China. But I don't know if it is made as an asthma drug.
It calmed #MastCells.
