Drug Guide

Generic Name

Budesonide; Formoterol Fumarate; Glycopyrrolate

Brand Names Breztri Aerosphere

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.

Nursing 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
