All that stuff is, Nasal Spray and Albuterol mixed, the problem is getting the nasal spray inhalable as it is thick, they must be using a dilution agent to get the mix right, but I bet a compound pharmacy could mix you up some.
I bet the cost this way is about $80 but for a lot more, but it cuts everyone out of the picture.

How to compound aerosols:

You just have to find a aerosol compounding pharmacy
I used a GoodRx coupon, which brought my copay down from $104 to the $81 I now pay. I know of one compounding pharmacy here in York (PA), but they don’t do aerosols. I’ll have to do some searching.
