Drug Guide
Budesonide; Formoterol Fumarate; Glycopyrrolate
Classification
Therapeutic: Bronchodilator, Anti-inflammatory, Combination inhaler for COPD
Pharmacological: Inhaled corticosteroid, Long-acting beta-agonist, Anticholinergic
FDA Approved Indications
- Treatment of chronic obstructive pulmonary disease (COPD) including chronic bronchitis and emphysema
Mechanism of Action
Budesonide reduces airway inflammation via corticosteroid effects; Formoterol is a long-acting beta2-adrenergic agonist that relaxes bronchial smooth muscle; Glycopyrrolate is an anticholinergic that blocks parasympathetic bronchoconstriction, leading to bronchodilation.
Dosage and Administration
Adult: Two inhalations twice daily inhalation of Breztri Aerosphere via the provided inhaler.
Pediatric: Not approved for pediatric use; safety and efficacy have not been established.
Geriatric: Use with caution, considering potential increased risk of side effects from all components.
Renal Impairment: No specific dosage adjustment recommended.
Hepatic Impairment: Use with caution; no specific dosage adjustments established.
Pharmacokinetics
Absorption: Systemic absorption occurs; bioavailability varies by component.
Distribution: Widely distributed; high pulmonary absorption.
Metabolism: Budesonide is extensively metabolized in the liver; Formoterol primarily metabolized hepatically; Glycopyrrolate undergoes minimal hepatic metabolism.
Excretion: Metabolites excreted primarily in urine and feces.
Half Life: Budesonide: approx. 2-4 hours; Formoterol: approx. 10 hours; Glycopyrrolate: approx. 2 hours.
Contraindications
- Hypersensitivity to any component.
- History of hypersensitivity to milk proteins (for inhaled corticosteroids).
Precautions
- Use caution in patients with infections, tachyarrhythmias, severe cardiac disease, or with a history of hypersensitivity reactions. Not for acute bronchospasm.
Adverse Reactions - Common
- Oral thrush (candidiasis) (Common)
- Tachycardia, palpitations (Common)
- Dry mouth (Common)
Adverse Reactions - Serious
- Paradoxical bronchospasm (Rare)
- Hypokalemia, hypotension (Rare)
- Cardiac arrhythmias (Rare)
Drug-Drug Interactions
- Other beta2-agonists, monoamine oxidase inhibitors, tricyclic antidepressants, other corticosteroids.
Drug-Food Interactions
N/ADrug-Herb Interactions
N/ANursing Implications
Assessment: Monitor lung function, assess for signs of infections or adverse effects.
Diagnoses:
- Impaired gas exchange
- Risk for infection
- Ineffective airway clearance
Implementation: Instruct patient on correct inhaler technique, monitor for side effects, evaluate effectiveness.
Evaluation: Assess improvement in respiratory symptoms, lung function tests, and adverse effects.
Patient/Family Teaching
- Use inhaler as prescribed, rinse mouth after corticosteroid use, report signs of infection or worsening symptoms.
- Avoid allergens or irritants that worsen COPD.
- Adherence to medication schedule is crucial.
Special Considerations
Black Box Warnings:
- Oral corticosteroids may increase the risk of pneumonia in COPD patients.
Genetic Factors: None specified.
Lab Test Interference: None noted.
Overdose Management
Signs/Symptoms: Severe allergic reactions, tachycardia, tremors, hypokalemia.
Treatment: Discontinue medication, supportive care, and symptomatic treatment as needed.
Storage and Handling
Storage: Store at room temperature away from moisture and heat.
Stability: Stable as per manufacturer guidelines until expiration date.
