title: Inhalation delivery of asthma drugs.
abstract: In the immediate future, metered-dose inhalers (MDIs) with spacers remain the aerosol application of choice for topical steroids, mainly to reduce side effects. For beta 2-agonist, anticholinergics and prophylactic drugs, MDI (with or without demand valve), dry powder inhalers (multidose inhalers), ultrasonic or jet aerosol generators (with or without mechanical breathing assistance [IPPB]) are chosen according to the preference or the ability of the patients to perform the necessary breathing maneuvers as well as the availability of different products in different countries.
