3, 7-Dimethylxanthine, a xanthine alkaloid, is used as a bronchodilator and as a vasodilator.

Theobromine (3,7-Dimethylxanthine) is a xanthine alkaloid that is used as a bronchodilator and as a vasodilator. [1] It has a weaker diuretic activity than theophylline and is also a less powerful stimulant of smooth muscle. [2] Unlike caffeine, Theobromine has practically no stimulant effect on the central nervous system. In contrast, It may improve mood and cognition via peripheral physiological changes. [3] It was formerly used as a diuretic and in the treatment of angina pectoris and hypertension. [4]
