Which of the following statements about antiasthma medications is true?

The statement about antiasthma medications being designed to prevent asthma attacks is accurate. Antiasthma medications are primarily classified into two categories: controller medications and rescue medications. Controller medications, which include inhaled corticosteroids and long-acting beta-agonists, are used daily to manage asthma symptoms and to reduce inflammatory responses in the airways. This preventive approach helps to maintain better asthma control and decrease the frequency of attacks over time.

On the other hand, rescue medications, such as short-acting beta-agonists, are used for immediate relief during an asthma attack but are not the primary focus of long-term asthma management. By understanding this differentiation, it becomes clear that the intent behind antiasthma medications is to help prevent airway inflammation and constriction associated with asthma, rather than simply addressing acute symptoms or acting solely on muscle relaxation.
