What medications are used for nebulization in upper respiratory tract infections?

For nebulized treatment of upper respiratory tract infections, commonly used medications mainly include: 1. Corticosteroids: such as budesonide suspension for inhalation. These have anti-inflammatory effects, reduce mucosal edema, and inhibit the production of inflammatory mediators, helping to relieve cough and control infection. 2. β2 receptor agonists: such as terbutaline sulfate nebulizer solution and salbutamol sulfate inhalation solution. These selectively stimulate β2-adrenergic receptors, leading to bronchodilation and relief of bronchospasm. 3. Mucolytic agents: such as ambroxol, which is used in cases of thick, viscous sputum and difficulty expectorating. It promotes sputum clearance by thinning mucus, making it easier to expel. 4. Others: depending on the causative pathogen, additional agents such as gentamicin injection (for bacterial infections) or interferon (for viral infections) may be selected for nebulization. All these medications must be used under the guidance of a qualified physician. Nebulization therapy is typically an adjunctive treatment; if patients present with other symptoms, combination therapy with other antimicrobial and anti-inflammatory drugs may also be required.
