Let's compare Albutrol and Levalbuterol

The question of using albuterol vs levaalbuterol to open airways keeps popping up in a variety of discussions.
Here's a small explanation - both Albuterol and Levalbuterol are short-acting beta-agonist drugs used to treat Asthma and other airway constriction.

Albuterol has been around for many years and is available as an inhaler, a solution for nebulizing, and (not common in the USA) as a pill or liquid suspension. Some people have unplesant reactions to albuterol such as rapid heartbeat or tremors.

Levalbuterol was developed some years ago for use as an inhaler or nebulized solution. It contains one of the two ingredients in albuterol, but is effective for many people with fewer side effects. It was originally sold under the brand name Xopenex, and was quite expensive.

Levalbuterol is now available as a generic, and the cost is only a little higher than albuterol - but a dose lasts 6-8 hours compared with 4-6 hours for original albuterol.
