To the Rescue: Fast-Acting Medications for Asthma Attacks
Despite an array of treatment options, inadequate medical treatment and undermedication often lead to emergent situations and may even be responsible for the increasing trend in asthma mortality. Whereas maintenance medications such as long-acting beta2 agonists, leukotriene receptor antagonists, and inhaled steroidsprevent asthma attacks, fast-acting or "rescue"medications are designed to stop the attack immediately. Rescue medications vary by setting and patient needs and include inhaled or intravenous (IV) beta2-agonist therapy, aminophylline, and magnesium.
