Antibiotics, anticholinergic and mucolytic agents can also be administered through a nebulizer. The difference between nebulizers and other inhalers is that a nebulizer turns the medication into a mist that goes directly into the lungs. There are two different types of nebulizers: pneumatic jet nebulizers and ultrasonic nebulizers.
