Warrick is albuterol. The empirical formula is C13H21NO3.
The sulfate is not counted against the base dosage of 90 mcg.
The insert for my ProAir©HFA states it delivers 108 µg albuterol sulfate (equivalent to 90 µg of albuterol).
They lowered the speed of delivery, and inreased the weight of the 'bullet'. The new formulation is not effective.
