Efficacy
For your asthma patients ≥12 years of age uncontrolled on an ICS or whose disease severity
clearly warrants an ICS/LABA
SYMBICORT provided significant and sustained* improvement in lung function,† with a majority of improvement occurring at 15 minutes2,3,‡
SYMBICORT provided twice the reduction in daytime and nighttime asthma symptom scores vs an ICS alone and reduced rescue medication use4,5
- SYMBICORT is NOT a rescue medication and does NOT replace fast-acting inhalers to treat acute symptoms
- Once asthma control is achieved and maintained, assess the patient at regular intervals and step down therapy (for example, discontinue SYMBICORT) if possible without loss of asthma control, and maintain the patient on a long-term asthma control medication, such as an ICS
*Sustained improvement in lung function was demonstrated in a 12-week efficacy and safety study.
†As measured by predose forced expiratory volume in 1 second (FEV1).
‡In patients taking SYMBICORT 160/4.5, 79% of 2-hour postdose FEV1 improvement occurred at 15 minutes on day of randomization, 89.25% at week 2, and 89.60% at end of treatment.

Study Design
Study 1: A 12-week efficacy and safety study
A 12-week, double-blind, placebo-controlled study comparing SYMBICORT 160/4.5 mcg, budesonide (BUD) 160 mcg, formoterol (FM) 4.5 mcg, the free combination of BUD 160 mcg plus FM 4.5 mcg in separate inhalers, and placebo, each administered as 2 inhalations twice daily. A total of 596 patients (124 randomized to receive SYMBICORT) ≥12 years of age were evaluated. The study included a 2-week run-in period with budesonide 80 mcg, 2 inhalations twice daily. Most patients had moderate to severe asthma and were using moderate to high doses of inhaled corticosteroids (ICSs) prior to study entry. This study was designed to assess 2 primary end points. The first was predose FEV1 averaged over 12 weeks, and the second was 12-hour average postdose FEV1 at week 2. Secondary efficacy variables included daytime and nighttime asthma symptom scores and daily rescue medication use (both recorded by patients in the electronic diary), predefined asthma events, and overall standardized Asthma Quality of Life Questionnaire (AQLQ) score.
SYMBICORT significantly reduced daytime and nighttime asthma symptoms vs an ICS alone4

aMean percent reduction in daytime and nighttime symptom scores for budesonide were 15% and 12%, respectively.
Placebo Comparison
Mean reduction in symptom scores over 12 weeks for placebo (%)
- Daytime symptoms: -6% (n=123)
- Nighttime symptoms: -11% (n=124)
Symptom Scoring
Daytime asthma symptom scores were recorded daily in the evening, and nighttime symptom scores for the previous night were recorded upon arising each morning. Symptom scores were rated on a scale of 0 to 3.
- 0=None; no symptoms of asthma
- 1=Mild symptoms; awareness of asthma symptoms and/or signs that are easily tolerated
- 2=Moderate symptoms; asthma symptoms with some discomfort, causing some interference with daily activities or sleep
- 3=Severe symptoms; incapacitating asthma symptoms and/or signs, with inability to perform daily activities or to sleep
SYMBICORT significantly reduced rescue medication use5

SYMBICORT is NOT a rescue medication and does NOT replace fast-acting inhalers to treat acute symptoms.
bBaseline is defined as the mean of all values obtained during the run-in period.
cTreatment average is defined as the mean of all values obtained during the double-blind treatment period.
dAdministered as 2 inhalations twice daily.

Important Safety Information, including Boxed warning
- WARNING: Long-acting beta2-adrenergic agonists (LABA), such as formoterol, one of the active ingredients in SYMBICORT, increase the risk of asthma-related death. A placebo-controlled study with another LABA (salmeterol) showed an increase in asthma-related deaths in patients receiving salmeterol. This finding with salmeterol is considered a class effect of LABA, including formoterol. Currently available data are inadequate to determine whether concurrent use of inhaled corticosteroids or other long-term asthma control drugs mitigates the increased risk of asthma-related death from LABA. Available data from controlled clinical trials suggest that LABA increase the risk of asthma-related hospitalization in pediatric and adolescent patients
- When treating patients with asthma, prescribe SYMBICORT only for patients not adequately controlled on a long-term asthma control medication, such as an inhaled corticosteroid or whose disease severity clearly warrants initiation of treatment with both an inhaled corticosteroid and LABA. Once asthma control is achieved and maintained, assess the patient at regular intervals and step down therapy (eg, discontinue SYMBICORT) if possible without loss of asthma control, and maintain the patient on a long-term asthma control medication, such as an inhaled corticosteroid. Do not use SYMBICORT for patients whose asthma is adequately controlled on low- or medium-dose inhaled corticosteroids
SYMBICORT is NOT a rescue medication and does NOT replace fast-acting inhalers to treat acute symptoms.
It is possible that systemic corticosteroid effects such as hypercorticism and adrenal suppression may occur, particularly at higher doses. Particular care is needed for patients who are transferred from systemically active corticosteroids to inhaled corticosteroids. Deaths due to adrenal insufficiency have occurred in asthmatic patients during and after transfer from systemic corticosteroids to less systemically available inhaled corticosteroids.
Patients who are receiving SYMBICORT should not use additional formoterol or other LABA for any reason.
Due to possible immunosuppression, potential worsening of infections could occur; a more serious course of chickenpox or measles can occur in susceptible patients.
Excessive beta-adrenergic stimulation has been associated with central nervous system and cardiovascular effects. SYMBICORT, like all products containing sympathomimetic amines, should be used with caution in patients with convulsive disorders, thyrotoxicosis, and cardiovascular disorders, especially coronary insufficiency, cardiac arrhythmias, and hypertension. Beta-adrenergic agonist medications may produce hypokalemia and hyperglycemia in some patients. As with other inhaled medications, paradoxical bronchospasm may occur with SYMBICORT. Use with caution in patients with diabetes mellitus.
Long-term use of orally inhaled corticosteroids, such as budesonide, a component of SYMBICORT, may result in a reduction in growth velocity and/or a loss of bone mineral density.
Glaucoma, increased intraocular pressure, and cataracts have been reported following the inhaled administration of corticosteroids, including budesonide, a component of SYMBICORT.
In rare cases, patients on inhaled corticosteroids may present with systemic eosinophilic conditions.
SYMBICORT should be administered with caution to patients being treated with MAO inhibitors or tricyclic antidepressants, or within 2 weeks of discontinuation of such agents. Caution should also be exercised in patients on long-term ketoconazole and other known potent CYP3A4 inhibitors.
Additional Information Specific to Asthma
The most common adverse reactions ≥3% reported in clinical trials included nasopharyngitis, headache, upper respiratory tract infection, pharyngolaryngeal pain, sinusitis, influenza, back pain, nasal congestion, stomach discomfort, vomiting, and oral candidiasis.
Additional Information Specific to COPD
- For patients with COPD, the approved dosage of SYMBICORT is 160/4.5 mcg, 2 inhalations twice daily
- The most common adverse events ≥3% reported in COPD clinical trials included nasopharyngitis, oral candidiasis, bronchitis, sinusitis, and upper respiratory tract infection
- Lower respiratory tract infections, including pneumonia, have been reported following the inhaled administration of corticosteroids
- In 2 placebo-controlled SYMBICORT COPD clinical studies, pneumonia did not occur with greater incidence in the SYMBICORT 160/4.5 group, compared with placebo, while the incidence of lung infections other than pneumonia (eg, bronchitis) was higher for SYMBICORT than placebo
Indications
SYMBICORT is indicated for the treatment of asthma in patients 12 years and older (also see Boxed WARNING).
SYMBICORT 160/4.5 is indicated for the maintenance treatment of airflow obstruction in patients with chronic obstructive pulmonary disease (COPD), including chronic bronchitis and emphysema.
SYMBICORT is NOT indicated for the relief of acute bronchospasm and should not be initiated in patients during rapidly deteriorating or potentially life-threatening episodes of asthma or COPD.
