Treatment of Chronic Asthma

© The intensity ofpharmacotherapy for chronic asthma is based on disease severity for initial therapy and level of control for subsequent therapies. The least amount of medications necessary to meet the goals of asthma therapy should be used.1 Current recommendations for stepwise therapy for chronic asthma are shown in Figure 14-2. However, because of varying asthma presentations, the therapeutic plan must be individualized. The EPR-3 separates treatment recommendations into three categories based on patient age: (a) children younger than 5 years of age, (b) childrenbetween the ages of 5 and 11 years, and (c) individuals 12 years of age and older. Refer to Ref. 1 for more information on assessing asthma control and adjusting therapy in these three categories.1

Intermittent Asthma

Long-term control medications are not necessary in patients with intermittent asthma, and patients should use an SABA to prevent or treat symptoms.1 This classification includes patients with exercise-induced asthma, seasonal asthma, or asthma symptoms associated with infrequent trigger exposure. Patients can pretreat with two puffs of al-buterol, cromolyn, or nedocromil prior to exposure to a known trigger.

Persistent Asthma

Patients who use an SABA more than twice a week for symptom control (not exercise-induced bronchospasm) should be treated as persistent asthma. Patients who experienced two or more exacerbations requiring oral corticosteroids in the past year may also be categorized as having persistent asthma.1 Patients with persistent asthma require daily long-term control therapy (see Tables 14-2 and 14-3). However, daily therapy limited to a predefined period of risk (e.g., seasonal asthma) may be considered when these periods are identified by history. ICS are the long-term control medication of choice at all levels of severity and in all age groups.1 SABAs should be prescribed for all patients with chronic asthma for use on an as-needed basis.

After initiating therapy, patients should be monitored within 2 to 6 weeks to ensure that asthma control has been achieved. Before increasing therapy, the patient's inhaler technique and adherence to therapy should be evaluated.1 Patients with controlled asthma should be monitored at 1-to 6-month intervals to ensure control is maintained. A gradual stepdown in control therapy should be initiated when possible, usually once control has been maintained for at least 3 months.1
