Quizplus · Accepted Answer

Dry powder inhalers are not recommended for use in acute exacerbation of asthma as they require a strong inspiratory effort which may be difficult for someone experiencing breathing difficulties during an acute attack. Metered-dose inhalers with a spacer or nebulizers are preferred as they can deliver medication more effectively to the lungs.
