concern about the preservatives in some albuterol solutions for nebulization
There's increasing concern about the preservatives in somealbuterol solutions for nebulization. These preservatives can causebronchoconstriction...making the albuterol less effective.
Benzalkonium chloride is a more potent bronchoconstrictorthan EDTA.
The problem is that even when the albuterol solutions aregenerically equivalent, they may contain different kinds andconcentrations of preservatives.
