Definition
-Selective, short-acting adrenergic agonist is initial drug of choice for acute bronchospasm -Direct action of inhaled medications on airways can be given in smaller doses with fewer adverse effects than oral or parenteral medications -Inhaled corticosteroids are used early in disease process when inflammation is established as major asthmatic component -In chronic disorders, inhaled corticosteroids should be taken on regular schedule using lowest dose required to control symptoms -Multidrug regimens offer advantage of smaller doses of each medication, which can decrease adverse effects, allow dosage increase as needed in exacerbations -Drug dosing must be individualized to attain most therapeutic effects with fewest adverse effects |
