no. in studies with children and adults the effects of hfa albuterol on lung function tests have been shown to be similar to cfc albuterol. with xopenex hfa some people get less jittery than with other albuterol inhalers. ventolin hfa has a dose counter so you know how many doses are left whereas proventil hfa and proair hfa do not have dose counters.
is one hfa inhaler more effective than another?
