mg/day inhaled via jet nebulizer either once daily or divided into 2 doses. The maximum manufacturer recommended total dose is 1 mg/day. The National Asthma Education and Prevention Program Expert Panel defines low dose therapy for budesonide inhalation suspension as mg/day, medium dose therapy as 1 mg/day, and high dose therapy as 2 mg/day for children ages 5 to 11 years. Titrate to the lowest effective dose once asthma stability is achieved. Prolonged use of high doses, ., 2 mg/day, may be associated with additional adverse effects.
Clinical efficacy for budesonide/formoterol maintenance therapy Clinical studies in adults have shown that the addition of formoterol to budesonide improved asthma symptoms and lung function, and reduced exacerbations. In two 12-week studies the effect on lung function of budesonide/formoterol was equal to that of the free combination of budesonide and formoterol, and exceeded that of budesonide alone. All treatment arms used a short-acting β 2 adrenoceptor agonist as needed. There was no sign of attenuation of the anti-asthmatic effect over time.
