Okay, this is important. There is a substantial difference between albuterol inhalers and albuterol tablets. Tablets such as Vospire ER maintain levels for about 8-12 hours and range in dosing from 2 to 8mg per tablet. Inhalers dispense about 90mcg per spray but have a much more immediate and efficient means of binding to the b2 receptors. You should not be taking inhalers for weight loss. The long acting tablets should be used if you decide to go the albuterol route. Equal dosage of the two does not produce equal results or effects - no where near. Stick with the tablets otherwise you are asking for trouble (not to mention it's cheaper).
