Which medication is commonly used for acute management of asthma exacerbations?

Albuterol is a short-acting beta-2 adrenergic agonist primarily utilized for the acute management of asthma exacerbations. Its mechanism of action involves relaxing the smooth muscle of the airways, leading to bronchodilation and rapid relief of bronchospasm. This is crucial during an asthma attack when the airways are constricted, allowing for improved airflow and alleviation of symptoms such as wheezing and shortness of breath.

In contrast, prednisone is a systemic corticosteroid that is effective in reducing inflammation in chronic asthma management but is not typically employed for immediate relief of acute symptoms. Montelukast is a leukotriene receptor antagonist used for long-term control and prevention of asthma symptoms rather than for acute treatment. Salmeterol is a long-acting beta-2 agonist that is intended for regular maintenance therapy and not for the quick relief of acute symptoms due to its delayed onset of action. Thus, albuterol stands out as the preferred choice during an asthma exacerbation.
