Brand Names Vanceril, Beclovent, Vancenase, Beconase, Vanceril Double Strength, Qvar 80, Qvar 40, Qnasl, Qvar Redihaler

Classification

Therapeutic: Anti-inflammatory corticosteroid

Pharmacological: Glucocorticoid receptor agonist

FDA Approved Indications

  • Asthma maintenance therapy
  • Allergic rhinitis (nasal spray)

Mechanism of Action

Beclomethasone Dipropionate is a corticosteroid that reduces inflammation by suppressing the immune response and inhibiting multiple cell types and mediator substances involved in allergic and inflammatory processes.

Dosage and Administration

Adult: Inhalation: typically 40-320 mcg twice daily, adjusted based on severity.

Pediatric: Start with 40-80 mcg twice daily, titrate to effect.

Geriatric: Use with caution, adjust doses based on response and tolerability.

Renal Impairment: No specific adjustment needed.

Hepatic Impairment: Use with caution; monitor for increased systemic effects.

Pharmacokinetics

Absorption: Minimal systemic absorption when inhaled, but some absorption occurs.

Distribution: Widely distributed in tissues, extensively bound to plasma proteins.

Metabolism: Metabolized in the liver via cytochrome P450 enzymes, mainly CYP3A4.

Excretion: Metabolites excreted primarily in urine.

Half Life: Approximately 2-3 hours for plasma; systemic effects depend on dose and formulation.

Contraindications

  • Hypersensitivity to beclomethasone or other corticosteroids.
  • Active systemic fungal infections.

Precautions

  • Use with caution in patients with active or dormant tuberculosis, herpes simplex infections, and during acute bronchospasm. Monitor for potential adrenal suppression with long-term high doses.

Adverse Reactions - Common

  • Mild throat irritation, cough (Common)
  • Oral candidiasis (thrush) (Occasional)

Adverse Reactions - Serious

  • Adrenal suppression (Rare)
  • Oropharyngeal candidiasis (Uncommon)
  • Respiratory infections (Uncommon)
  • Behavioral changes in children (e.g., hyperactivity) (Rare)

Drug-Drug Interactions

  • Cytochrome P450 3A4 inhibitors (e.g., ketoconazole) may increase systemic corticosteroid levels.

Nursing Implications

Assessment: Monitor lung function, symptom control, and for signs of adverse effects like oral thrush or changes in behavior in children.

Diagnoses:

  • Impaired gas exchange
  • Risk for infection
  • Ineffective airway clearance

Implementation: Administer via inhaler or nasal spray as prescribed, rinse mouth after inhalation, educate on proper inhaler technique.

Evaluation: Assess symptom improvement, monitor for side effects, and ensure proper inhaler use.

Patient/Family Teaching

  • Use regularly as prescribed for best results.
  • Rinse mouth and spit out after inhalation to prevent thrush.
  • Report any oral sores, hoarseness, or side effects.
  • Do not stop abruptly without consulting healthcare provider.

Special Considerations

Black Box Warnings:

  • Systemic corticosteroids may cause adrenal suppression, hyperglycemia, and other systemic effects, especially with high doses or prolonged use.

Genetic Factors: Pharmacogenetic variations affecting metabolism via CYP3A4 may alter drug levels.

Lab Test Interference: May alter growth in children; may affect cortisol levels.

Overdose Management

Signs/Symptoms: Symptoms of systemic corticosteroid excess, such as weight gain, fluid retention, hypertension.

Treatment: Discontinue use, provide symptomatic treatment, and support as needed. Seek emergency care if overdose is severe.

Storage and Handling

Storage: Store at room temperature, away from moisture and light.

Stability: Stable until expiration date on the package.
