Aerosol therapy involves inhaling fine particles or pharmacological substances through an aerosolizing device. This treatment is used for respiratory diseases such as asthma, bronchitis, or other lung conditions. The aerosolized particles reach the deeper respiratory passages, allowing for greater effectiveness in delivering the medication directly to the lungs. Aerosol can be administered through a nebulizer or a pressurized inhaler. This therapy helps reduce inflammation, improve lung function, and alleviate respiratory symptoms.
