Sustained-release theophylline is an alternative Sho acting Beta- agonist as needed and before exercise; daily use or increasing use may indicate need for additional long term control therapy Step 3: Moderate persistent Daily symptoms, daily use of sho acting beta- agonists 1 timeweek FEV1 or PEF 60-80 of predicted; PEF variability 30 Anti inflammatory: inhaled coicosteroids median dose or inhaled glucocoicoids low dose and either long acting beta agonist LABA , leukotriene modifier, sustained release theophylline, or LABA tablets Sho acting beta agonist as needed and before exercise; daily use or increasing use may indicate eed for additional long term control therapy. Step 4: severe persistent Continual symptoms, limited physical activity, frequent exacervations Frequent FEV1 or PEF 60 of predicted; PEF variability30 Anti inflammatory: inhaled glucocoicoids high dose and either long acting beta- agonist LABA , leukotriene modifier, sustained release theophylline, or LABA tablets Oral glucocoicoids if needed.
