[Advantages and difficulties of aerosol therapy]

Aerosolization of drugs may be designed to treat lower respiratory tract and bronchial diseases and more recently infectious diseases of the lungs. The use of drug aerosol has been limited by the relative lack of knowledge about the fate of inhaled drugs. It depends on the specifications of the aerosol, the drug itself, the conditions of aerosolization, and the presence of lung disease. The advantage of the airways route is that treatment effects are obtained without systemic effects.
