What is the correct dosage of ipratropium bromide during an asthma attack?

• A. 0.25 mg by nebulizer
• B. 0.5 mg by nebulizer
• C. 1.0 mg by nebulizer
• D. 2.5 mg by nebulizer

Answer: (B)

Ipratropium bromide is an anticholinergic medication commonly used to facilitate bronchodilation during asthma attacks. The standard dosage for treating an acute asthma episode in adults is typically 0.5 mg via nebulization. This dosage is effective in helping to open the airways and improve airflow by blocking the action of acetylcholine, which can lead to bronchoconstriction. Utilizing 0.5 mg allows for a sufficient therapeutic effect while minimizing potential side effects associated with higher doses. It is important to use this medication as part of a comprehensive treatment plan that may include other bronchodilators and corticosteroids, especially in severe cases. In the context of other potential dosages, lower doses like 0.25 mg may not provide the necessary bronchodilation for acute exacerbations, while higher doses such as 1.0 mg or 2.5 mg exceed the established guideline for nebulized administration in this situation, which could increase the risk of adverse effects without necessarily improving clinical outcomes.
