Abstract

Current methods of inhaled therapy using gas-propelled nebulizers lack standardization. The frequent use of nebulized therapy in a continuous flow may be the major reason for the inconsistency of the actual fraction of nebulized drug delivered to the patient. In an effort to achieve consistency in the amount of drug delivered to the patient, we evaluated an intermittent system of nebulized therapy, using a fingertip controlled nebulizer, in 18 adolescent asthmatics. This mode of delivery was found to be highly efficient, providing a nebulized fraction of more than 70% of the initial volumes used (0.75 to 2.6 mL). Initial volumes of 0.9 mL and above were equally efficacious, indicating no further benefit of using higher volumes. Nebulized fractions were found to be highly consistent from one patient to another (+/- 1 SD of 14.1%). We conclude that control of the actual dose delivered to the patient can be best achieved through an intermittent mode of delivery.

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.
