The vast majority of bronchitis is from a viral infection which means that antibiotics will not work. However, in the case of secondary bacterial infection an antibiotic can be useful in killing of the bacterial source of infection.
As for albuterol, it is called a beta-agonist and is used to dilate the airway to help the passage of air when their is obstruction (in this case due to increased mucous). Albuterol is not a steriod. Steroid sprays such as Flovent are used to decrease inflammation.
In my own personal experience with bronchitis in my little girl, I have used a humidifier, lots and lots of fluids, tylenol/advil as a fever reducer, and a whole bunch of watchful waiting.
