Study Notes
Advair Overview
- Generic name: Fluticasone Propionate with Salmeterol Xinafoate
- Class: Antiasthmatic
Dosage Forms
- Diskus:
- Available in strengths: 100/50, 250/50, 500/50
- Each dose contains 50 mcg salmeterol (as 72.5 mcg salmeterol xinafoate) with either 100, 250, or 500 mcg fluticasone propionate
- HFA:
- Available in strengths: 45/21, 115/21, 230/21
- Each dose contains 21 mcg salmeterol (as 30.45 mcg salmeterol xinafoate) with either 45, 115, or 230 mcg fluticasone propionate
Indications and Dosages
- Long-term asthma maintenance: 1 Diskus inhalation or 2 HFA inhalations twice daily (12 hours apart)
- COPD treatment: 1 inhalation of Advair 250/50 twice daily (morning and evening)
Recommended Dosage
- Consistent administration: 1 Diskus inhalation or 2 HFA inhalations twice daily, spaced 12 hours apart
Mechanism of Action
- Fluticasone propionate: Synthetic, trifluorinated corticosteroid
- Corticosteroids bind to specific receptor proteins in the cytoplasm, forming a steroid-receptor complex
- This complex interacts with chromatin or DNA, influencing m-RNA transcription
- Stimulation of m-RNA leads to the synthesis of proteins and enzymes with anti-inflammatory effects
Salmeterol Action
- Stimulates adenyl cyclase, increasing c-AMP from ATP
- Increased c-AMP results in:
- Relaxation of bronchial, uterine, and vascular smooth muscle via beta-2-adrenergic receptors
- Inhibition of mediators of immediate hypersensitivity from mast cells
Pharmacokinetics
- Onset: Within 20 minutes
- Duration: Approximately 12 hours
Drug Interactions
- Beta-blockers may reduce Advair's effectiveness
- Other sympathomimetics, tricyclic antidepressants, and monoamine oxidase inhibitors can heighten toxicity
Contraindications and Precautions
- Not for primary treatment of status asthmaticus
- Avoid use with long-acting beta-2-adrenergic agonists
- Use cautiously in patients transitioning from systemic corticosteroids (may require systemic steroids during stress events)
- Not for rapid relief of bronchospasm
- Risk of fungal infections in the mouth
- Caution in patients with cardiovascular disease, hypertension, hyperthyroidism, diabetes mellitus, and nursing mothers
- Pregnancy category C
Adverse Effects
- Common effects include upper respiratory tract infections, pharyngitis, headache, nausea, vomiting, sinusitis, bronchitis, cough, rash, and angioedema
Patient Consultation
- Avoid eye contact and rinse mouth post-use
- Report prolonged side effects to a physician
- Missed doses: skip and resume normal schedule
- Not for immediate relief; use regularly for optimal benefits
- Ensure proper usage technique is understood
