Aminophylline is a xanthine drug whose mechanism of action is to inhibit the activity of phosphodiesterase, which has the effect of relieving bronchospasm, dilating coronary arteries, and having a diuretic effect. Therefore, it can be used to treat both asthma and acute cardiac insufficiency and cardiogenic asthma. When aminophylline is used to treat cardiogenic asthma, aminophylline can be given as continuous intravenous pumping, which can reduce the side effects of aminophylline and achieve the effect of treating asthma at the same time. When it is not clear whether it is cardiogenic asthma, or asthma-induced wheezing symptoms, aminophylline can be given intravenously first, and if the symptoms are significantly relieved, other drugs can be applied after judging the condition. If it is cardiogenic asthma, it is also recommended to give cardiotonic, diuretic and vasodilator drugs, such as cetiran, tachyphylaxis and isosorbide nitrate drugs.
