Albuterol is the most commonly prescribed fast-acting inhaler. Combivent has both albuterol AND atrovent. There is also maxair. Like previously posted, there is Xopenex, but at this moment, it only comes in nebulizer form. They are working on the MDI form, but it's still in its third phase of FDA testing.

I'm also an intrinsic asthmatic and I find that atrovent works okay in a pinch, and Xopenex does well sometimes too...Though sometimes, nothing can touch it.
