Theophylline, ephedrine, and phenobarbital combination is used to treat the symptoms of bronchial asthma, asthmatic bronchitis, and other lung diseases. This medicine relieves cough, wheezing, shortness of breath, and troubled breathing. It works by opening up the bronchial tubes (air passages) of the lungs and increasing the flow of air through them.
