Diprophylline or dyphylline, is a xanthine derivative with bronchodilator and vasodilator effects. It is used in the treatment of respiratory disorders like asthma, cardiac dyspnea, and bronchitis. It acts as an adenosine receptor antagonist and phosphodiesterase inhibitor.

Dyphylline has been used in the treatment of acute and chronic bronchial asthma, chronic bronchitis, and emphysema; however, aminophylline, oxtriphylline, and theophylline are considered safer and more effective.
