Noradrenaline bitartrate

The main ingredient is: norepinephrine bitartrate, and its chemical name is: (R)-4-(2-amino-1-hydroxyethyl)-1,2-benzenediol bitartrate monohydrate.

When used with general anesthetics such as chloroform, cyclopropane, and halothane, the myocardium may be more sensitive to sympathomimetic amines, and ventricular arrhythmias may occur easily. They should not be used together. If they must be used together, the dosage should be reduced. 1 When used with beta-blockers, the efficacy of each is reduced. After beta-receptor blockade, the effect of alpha receptors is prominent, and hypertension and bradycardia may occur. 2 When used with antihypertensive drugs, it can offset or weaken the effect of antihypertensive drugs. When used with methyldopa, the pressor effect of this product is also enhanced. 3 When used with digitalis, it is easy to cause arrhythmias, and close attention should be paid to ECG monitoring. 4 When used with other sympathomimetic amines, the cardiovascular effect is enhanced. 5 When used with ergot preparations such as ergotamine, ergonovine, or oxytocin, vasoconstriction is enhanced, causing severe hypertension and bradycardia. 6. When used in combination with tricyclic antidepressants, the cardiovascular effects of this product may be enhanced by inhibiting tissue absorption of this product or enhancing the sensitivity of adrenaline receptors, causing arrhythmia, tachycardia, hypertension or hyperthermia. If it must be used in combination, the initial dosage of this product should be small and the cardiovascular effects should be monitored. 7. When used in combination with thyroid hormones, the effects of both are enhanced. 8. When used in combination with tolazoline, it may cause a drop in blood pressure, followed by an excessive rebound increase in blood pressure. Therefore, this product should not be used when tolazoline is overdosed.
