- Corticosteroid, Inhalant (Oral)
Formoterol relaxes bronchial smooth muscle by selective action on beta2 receptors with little effect on heart rate. Formoterol has a long-acting effect. Budesonide is a corticosteroid which controls the rate of protein synthesis, depresses the migration of polymorphonuclear leukocytes/fibroblasts, and reverses capillary permeability and lysosomal stabilization at the cellular level to prevent or control inflammation.

Symbicort 80/4.5, Symbicort 160/4.5: Prior to first use, inhaler must be primed by releasing 2 test sprays into the air; shake well for 5 seconds before each spray. Inhaler must be reprimed if not used for >7 days or if it has been dropped. Shake well for 5 seconds before each use. Discard inhaler after the labeled number of inhalations have been used or within 3 months after removal from foil pouch (do not use the “float test” to determine amount remaining in canister).
Symbicort Turbuhaler [CAN; not available in U.S.]:
To “load” inhaler: Turn grip on inhaler as far as it will move in one direction, then turn in opposite direction as far as it will go (inhaler is “loaded” with a dose, indicated by a “click”). Prior to first use, this procedure should be done twice, it does not need to be repeated with subsequent uses even when not used regularly.
Delivery of dose: Instruct patient to place mouthpiece gently between teeth, closing lips around inhaler. Instruct patient to inhale deeply and hold breath held for 5 to 10 seconds. The amount of drug delivered is small, and the individual will not sense the medication as it is inhaled. Remove mouthpiece prior to exhalation. Patient should not breathe out through the mouthpiece. After use of the inhaler, patient should rinse mouth/oropharynx with water and spit out rinse solution.
Symbicort 80/4.5, Symbicort 160/4.5: Store at room temperature of 20°C to 25°C (68°F to 77°F) with mouthpiece down. Do not puncture, incinerate, or store near heat or open flame. Discard inhaler after the labeled number of inhalations have been used or within 3 months after removal from foil pouch.

Concerns related to adverse effects:
• Adrenal suppression: May cause hypercorticism or suppression of hypothalamic-pituitary-adrenal (HPA) axis, particularly in younger children or in patients receiving high doses for prolonged periods. HPA axis suppression may lead to adrenal crisis. Withdrawal and discontinuation of a corticosteroid should be done slowly and carefully. Particular care is required when patients are transferred from systemic corticosteroids to inhaled products due to possible adrenal insufficiency or withdrawal from steroids, including an increase in allergic symptoms. Patients receiving >20 mg per day of prednisone (or equivalent) may be most susceptible. Fatalities have occurred due to adrenal insufficiency in asthmatic patients during and after transfer from systemic corticosteroids to aerosol steroids; aerosol steroids do not provide the systemic steroid needed to treat patients having trauma, surgery, or infections. Do not use this product to transfer patients from oral corticosteroid therapy.
• Asthma-related deaths: [US Boxed Warning]: Long-acting beta2-agonists (LABAs), such as formoterol, increase the risk of asthma-related deaths; budesonide/formoterol should only be used in patients not adequately controlled on other long-term asthma control medication (ie, inhaled corticosteroid) or whose disease severity requires initiation of 2 maintenance therapies. In a large, randomized, placebo-controlled US clinical trial (SMART, 2006), salmeterol was associated with an increase in asthma-related deaths (when added to usual asthma therapy); risk is considered a class effect among all LABAs. Data are not available to determine if the addition of an inhaled corticosteroid lessens this increased risk of death associated with LABA use; however, current guidelines recommend the use of an inhaled corticosteroid before adding a LABA (GINA 2015; NIH/NHLBI 2007). Assess patients at regular intervals once asthma control is maintained on combination therapy to determine if step-down therapy is appropriate (without loss of asthma control), and the patient can be maintained on an inhaled corticosteroid only. LABAs are not appropriate in patients whose asthma is adequately controlled on low- or medium-dose inhaled corticosteroids. In a more recent multicenter, randomized, double-blinded trial, the use of salmeterol and an inhaled corticosteroid (ie, fluticasone) combined in a single inhaler in a large number of children, adolescent, and adult patients with persistent asthma (non-life threatening and stable) did not increase the risk of serious asthma-related events compared with fluticasone alone; in addition, patients receiving fluticasone/salmeterol had fewer severe asthma exacerbations compared with patients receiving fluticasone alone (Peters 2016; Stempel 2016a; Stempel 2016b ).
• Bone density: Long-term use may decrease bone mineral density in adults.
• Bronchospasm: Rarely, paradoxical bronchospasm may occur with use of inhaled bronchodilating agents; this should be distinguished from inadequate response.
• Hypersensitivity reactions: Immediate hypersensitivity reactions (urticaria, angioedema, rash, bronchospasm) have been reported.
• Immunosuppression: Prolonged use of corticosteroids may increase the incidence of secondary infection, mask acute infection (including fungal infections), prolong or exacerbate viral infections, or limit response to vaccines. Exposure to chickenpox should be avoided; corticosteroids should not be used to treat ocular herpes simplex. Corticosteroids should not be used for cerebral malaria. Close observation is required in patients with latent tuberculosis and/or TB reactivity. Restrict use in active TB (only in conjunction with antituberculosis treatment).
• Lower respiratory infections: Pneumonia and other lower respiratory tract infections have been reported in patients with COPD following the use of inhaled corticosteroids; monitor COPD patients closely since pneumonia symptoms may overlap symptoms of exacerbations.
• Oral candidiasis: Infections with Candida albicans in the mouth and throat (thrush) have been reported with use.
• Serious effects/fatalities: Do not exceed recommended dose; serious adverse events, including fatalities, have been associated with excessive use of inhaled sympathomimetics.
• Vasculitis: Rare cases of vasculitis (Churg-Strauss syndrome) have been reported with use of inhaled corticosteroid
• Asthma: Appropriate use: Do not use for acute bronchospasm. Short-acting beta2-agonist (eg, albuterol) should be used for acute symptoms and symptoms occurring between treatments. Do not initiate in patients with significantly worsening or acutely deteriorating asthma.
• Cardiovascular disease: Use with caution in patients with cardiovascular disease (arrhythmia or hypertension or HF); beta agonists may cause elevation in blood pressure, heart rate and result in CNS stimulation/excitation. Beta2-agonists may also increase risk of arrhythmias.
• COPD: Appropriate use: Do not use for acute episodes of COPD. Do not initiate in patients with significantly worsening or acutely deteriorating COPD. Data are not available to determine if LABA use increases the risk of death in patients with COPD.
• Diabetes: Use with caution in patients with diabetes mellitus; beta2-agonists may increase serum glucose.
• Hepatic impairment: Use caution; budesonide and formoterol are hepatically cleared.
• Hypokalemia: Use with caution in patients with hypokalemia; beta2-agonists may decrease serum potassium.
• Ocular disease: Use with caution in patients with cataracts and/or glaucoma; increased intraocular pressure, open-angle glaucoma, and cataracts have occurred with prolonged use. Consider routine eye exams in chronic users.
• Osteoporosis: Use with caution in patients with osteoporosis; high doses and/or long-term use of corticosteroids have been associated with increased bone loss and osteoporotic fractures.
• Seizure disorders: Use with caution in patients with seizure disorders; beta agonists may result in CNS stimulation/excitation.
• Thyroid disease: Changes in thyroid status may necessitate dosage adjustments; metabolic clearance of corticosteroids increases in hyperthyroid patients and decreases in hypothyroid ones.
Concurrent drug therapy issues:
• High potential for interactions: Use with caution in patients taking strong CYP3A4 inhibitors (see Drug Interactions); consider alternative agents that avoid or lessen the potential for CYP-mediated interactions.
• Pediatric: [US Boxed Warning]: LABAs may increase the risk of asthma-related hospitalization in pediatric and adolescent patients. Orally-inhaled and intranasal corticosteroids may cause a reduction in growth velocity in pediatric patients (~1 centimeter per year [range 0.3-1.8 cm per year] and related to dose and duration of exposure). To minimize the systemic effects of orally-inhaled and intranasal corticosteroids, each patient should be titrated to the lowest effective dose. Growth should be routinely monitored in pediatric patients.
Dosage form specific issues:
• Lactose: Some products (available in Canada) contain lactose; very rare anaphylactic reactions have been reported in patients with severe milk protein allergy.
• Discontinuation of therapy: Withdraw systemic therapy with gradual tapering of dose. There have been reports of systemic corticosteroid withdrawal symptoms (eg, joint/muscle pain, lassitude, depression) when withdrawing oral inhalation therapy.
• Patient information: Patients must be instructed to seek medical attention in cases where acute symptoms are not relieved by short-acting beta-agonist (not formoterol) or a previous level of response is diminished. Medical evaluation must not be delayed. Patients using inhaled, short acting beta2-agonists should be instructed to discontinue routine use of these medications prior to beginning treatment with Symbicort®; short acting agents should be reserved for symptomatic relief of acute symptoms. Patients should not use additional long-acting beta2-adrenergic agonists.
FEV1, peak flow meter and/or other pulmonary function tests; monitor growth in pediatric patients, symptom relief, monitor for increased use if short-acting beta2-adrenergic agonists (may be a sign of asthma or COPD deterioration)
Pregnancy Risk Factor
Adverse events were observed in animal reproduction studies using this combination. Refer to individual agents.
• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
• Patient may experience pharyngitis, throat pain, back pain, abdominal pain, or rhinitis. Have patient report immediately to prescriber signs of infection, signs of high blood sugar (confusion, fatigue, increased thirst, increased hunger, polyuria, flushing, fast breathing, or breath that smells like fruit), signs of low potassium (muscle pain or weakness, muscle cramps, or an abnormal heartbeat), signs of adrenal gland problems (severe nausea, vomiting, severe dizziness, passing out, muscle weakness, severe fatigue, mood changes, lack of appetite, or weight loss), angina, tachycardia, anxiety, mouth sores, bone pain, dizziness, passing out, seizures, severe headache, tremors, severe nausea, vomiting, severe loss of strength and energy, insomnia, burning or numbness feeling, flu-like signs, sinusitis, vision changes, eye pain, severe eye irritation, thrush, or signs of a severe pulmonary disorder (lung or breathing problems like difficulty breathing, shortness of breath, or a cough that is new or worse) (HCAHPS).
• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
