Because inflammation has been established as a major verse effects (oropharyngeal candidiasis, hoarseness) component of asthma, an inhaled corticosteroid is being can be decreased by reducing the dose, administering less often, rinsing the mouth after use, or using a spacer device. These measures decrease the amount of drug deposited in the oral cavity. A common regimen for treatment of moderate asthma is an inhaled corticosteroid on a regular schedule, Keith Wilson, 66 years of age, has worsening chronic obstructive pulmonary disease. At his last office visit, his physician added ipra- two to four times daily, and a short-acting, inhaled tropium bromide (Atrovent) and beclomethasone (Vanceril) to his beta2-adrenergic agonist as needed for prevention or beta-adrenergic (Alupent) inhaler.
