Study Notes
Aerosol Therapy
- Effective aerosol therapy requires a device that quickly delivers sufficient drug to the desired site of action with minimal waste and at a low cost.
Aerosol Generators
- Aerosol generators in use include pressurized metered dose inhalers (pMDIs), dry powder inhalers (DPIs), small and large volume (jet) nebulizers, and ultrasonic nebulizers (USNs).
Pressurized Metered Dose Inhalers (pMDIs)
- Portable, compact, and easy to use
- Provides multidose convenience
- Dispenses a uniform dose of drug within a fraction of a second after actuation
- Reproducible throughout the canister life
- Designed for specific drug formulation and dose volume to be delivered
- Used to administer bronchodilators, anticholinergics, and steroids
Transnasal Pulmonary Aerosol Delivery
- Transnasal pulmonary aerosol delivery via nasal cannula has gained popularity
- Pediatric patients with bronchiolitis or asthma experience reduced anxiety and increased comfort when inhaling bronchodilators through nasal cannula
Clinical Applications
- High-Flow Nasal Cannula (HFNC) is used for administering bronchodilators for asthma or COPD
- HFNC is used for administering inhaled epoprostenol for pulmonary hypertension
Transnasal Pulmonary Aerosol Delivery System
- Consists of a nebulizer, a heater/humidifier, and a nasal cannula
- Air/oxygen is delivered to the nebulizer, creating a mist of medication
- The mist is delivered to the patient through the nasal cannula
