Ask any questions you like. I will say a little to start. Two classes of drugs are prescribed for persistent asthma. Anti-inflammatory medicine and bronchodilator medicine. Both are most effective if inhaled.
Every asthmatic also needs a rescue inhaler for acute bronchoconstriction.
The most well known is albuterol. I am currently on Accolate. It takes at least 3-4 weeks to notice whether it is helping. No reason to stay on it if it doesn't help. The leukotriene modifiers seem to be more effective in people whose asthma is aggravated by allergens.
