Proxyphylline

Proxyphylline is a cardiotonic drug that belongs to the xanthine family. It is used in the treatment of asthma, chronic obstructive pulmonary disease (COPD), and other respiratory disorders. Proxyphylline works by relaxing the smooth muscle in the airways, which allows for easier breathing.
