Newer medications to aid treatment of asthma.

The selective beta-2 adrenergic bronchodilator preparations should be considered the medications for the first line of defense in the treatment of the average asthmatic patient. Theophylline and derivatives of theophylline are the second line of defense. Cromolyn sodium, atropine and derivatives, corticosteroids and other selected agents follow, depending on the individual case and the circumstances involved.
