Drug Guide
Beclomethasone Dipropionate
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.
Drug-Food Interactions
N/ADrug-Herb Interactions
N/ANursing 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.
