A member asked:

My albuterol inhalation aerosol (warwick pharmaceuticals) helps me, but i've been switched to albuterol sulfate (pro air) which has less benefit, why?

Sensations or dose: The standard dose for a puff of albuterol is 90 micrograms, so any of the preparations should be the same in effect. Recently, the gas that pushes the medicine out of the inhaler, called the propellant, was changed. Some people feel that the new propellant (called hfa) is not as strong as what was used before. If the dose and propellant are the same, it is likely to be your sensation of effect.
