Delivery of Inhaled Medication in Children: Revisiting Pharmacological and Practical Issues for Better Health Outcome

Abstract

For safe and effective therapy of respiratory disorders in children, delivering the medication at the site of disease i.e. directly into the respiratory tract via aerosolized medication is critical. But, the anatomical and physiological differences in the respiratory tract of infants/children and adults make the delivery of aerosolized medication complicated. This review article gives an overview of the delivery of inhaled medication in children and discuss the pharmacological and specific clinically relevant aspects of medication delivery using nebulizers, pressurized metered dose inhalers (MDIs), and dry powder inhalers (DPIs) in children. As a physician, one should always keep in mind the various factors like properties of the device, aerosol particle, patient factors such as disease state, ventilatory pattern, and administration technique that can affect drug deposition via aerosol delivery devices.
