1. Act directly on the respiratory tract: The nebulizer refines the drug into tiny particles, so they can penetrate deeper into the lungs of the respiratory system and directly exert the therapeutic effect of the drug. This is very beneficial in treating asthma, chronic obstructive pulmonary disease (COPD), and other respiratory conditions.

2. Quickly relieve symptoms: By atomizing drugs, the drugs can be absorbed and delivered to the areas in need faster, thereby quickly relieving symptoms and providing a rapid soothing effect. This is important in the treatment of acute respiratory infections, airway spasms, or other acute symptoms.

3. Improve drug absorption efficiency: Compared with oral drugs, nebulizers can deliver drugs to the lungs, bypassing the digestive process of the gastrointestinal tract. This increases the efficiency of absorption of the medication and reduces the risk of stomach acid or digestive juices affecting the effectiveness of the medication.
