This seemed to be an excellent article on the use of prednisone and other corticosteroids, and touched specifically on asthma sufferers and the use of inhalers. I thought this was highly informative and would highly recommend reading it.

Great page — accessible, informative, relevant, concise. It specifically addresses the use of prednisone as an inhaler or spray for asthma and how it is used to suppress inflammation in asthma treatment.
