Which medication is contraindicated in acute asthma attacks?

In the context of acute asthma attacks, long-acting beta agonists are contraindicated because they are not intended for the immediate relief of acute symptoms. Instead, these types of medications are used as a maintenance therapy for asthma control and require time to build up their effects. During an acute asthma attack, rapid bronchodilation is necessary, and long-acting beta agonists do not provide the quick action required to relieve severe bronchoconstriction.

Short-acting beta agonists are specifically designed for quick relief and are the first-line treatment during an acute asthma attack. Corticosteroids are beneficial for reducing inflammation and can be used in acute situations, but they do not provide immediate relief. Anticholinergics may be used for their bronchodilator effect but are also not the first choice for acute attacks. Therefore, the primary concern with long-acting beta agonists in the scenario of an acute asthma assault is their slow onset of action, making them unsuitable for these urgent situations.
