Terbutaline typically requires 5 mg per use when nebulized for inhalation, budesonide is typically used at a dosage of 1-2 mg per nebulized inhalation for adults and 0.5-1 mg per use for children. Terbutaline and budesonide are commonly used nebulized preparations, with terbutaline being a short-acting beta2 agonist with rapid airway dilation. When treated by nebulized inhalation, 5 mg is usually used at a time. Budesonide belongs to the glucocorticoid class of drugs, with anti-inflammatory effects when nebulized inhalation, larger doses of budesonide suspension can also quickly improve the patient’s symptoms of chest tightness and wheezing. The usual dosage for adults is 1 to 2 milligrams per dose; children’s budesonide suspension needs to be reduced as appropriate, usually 0.5 to 1 milligram per dose. Although terbutaline and budesonide have fewer side effects when nebulized for inhalation, they may induce spasms in the airway, leading to worsening of chest tightness. Whereas terbutaline may also cause adverse reactions such as panic and hand tremors, budesonide may cause hoarseness as well as increase the incidence of respiratory infections. Therefore, terbutaline and budesonide need to be used under a doctor’s supervision and the drugs need to be monitored for adverse effects.
