Treatment of asthma, bronchitis, and related respiratory conditions involving bronchoconstriction and excessive mucus production. May be used for symptomatic relief in COPD and other obstructive airway diseases.
Theophylline and ephedrine act as bronchodilators by relaxing airway smooth muscle. Guaifenesin thins and loosens mucus in the airways. Butabarbital provides mild sedation to reduce anxiety and restlessness associated with respiratory distress.
Barbiturates like butabarbital carry risks of dependence and should be used cautiously. Theophylline has a narrow therapeutic window requiring monitoring. This combination may interact with other medications affecting the heart or nervous system. Not typically used as first-line therapy in modern practice.
