Vasicine has been compared to theophylline both in vitro and in vivo. It has also been studied in combination with the related alkaloid vasicinone. Both the alkaloids in combination (1:1) showed pronounced bronchodilatory activity in vivo and in vitro. Both alkaloids are also respiratory stimulants. Vasicine has a cardiac–depressant effect, while vasicinone is a weak cardiac stimulant; the effect can be normalized by combining the alkaloids. Vasicine is reported to have a uterine stimulant effect.
