Medication Dose Mechanism Comment
Albuterol Intermittent 2.5 mg nebulization or ß2-agonist: bronchodilation via airway smooth muscle relaxation Frequent re-evaluation needed, especially if tachycardic
Continuous nebulization from 5–20 mg/hr Side effects: tremor, tachycardia, agitation, hypokalemia
Acetylcysteine Infants: 1–2 mL of 20% solution or 2–4 mL of 10% solution (undiluted); three to four times daily Exerts mucolytic action through its free sulfhydryl group, which opens up the disulfide bonds in the mucoproteins, thus lowering mucous viscosity
Children and adolescents: 3–5 mL of 20% solution or 6–10 mL of 10% solution (undiluted); administer three to four times daily
Ipratropium 125–500 mcg nebulization q6–8 hr Inhaled anticholinergic (inhibit cGMP) bronchodilator Systemic SEs rare due to poor absorption from lung
Saline nebulization 0.9%, 3%, 7% 3% solution: 4 mL inhaled every 2 hr Pretreatment with a bronchodilator is recommended to prevent potential bronchospasm
≥6 years and adolescents: inhalation: 7% solution: 4 mL inhaled twice daily
Terbutaline Load: 2–10 mcg/kg IV Systemic ß2-agonist SEs same as albuterol
Infusion: 0.08–1 mcg/kg/min Stop infusion and obtain ECG for chest pain or ST changes
