Typical symptoms are cough, shortness of breath, chest tightness, and in some severe cases, respiratory failure and circulatory failure. The main treatment is glucocorticoids such as budesonide, leukotriene modifiers such as montelukast sodium, theophyllines such as aminophylline, and other theophyllines. Generally, nebulization and oral medication are preferred for mild asthma attacks, such as nebulization of budesonide and terbutaline, and oral medication such as montelukast sodium and loratadine.
