化学的特性Esmolol Hydrochloride is a white to off-white crystalline powder. It is a relatively hydrophilic compound which is very soluble in water and freely soluble in alcohol. Its partition coefficient (octanol/water) at pH 7.0 is 0.42 compared to 17.0 for propranolol.Esmolol Hydrochloride has the empirical formula C16H26NO4Cl and a molecular weight of 331.8. It has one asymmetric center and exists as an enantiomeric pair.

説明Esmolol is an ultra-short acting, cardioselective P-blocker with no intrinsic sympathomimetic activity. The capability of rapid reversal makes esmolol uniquely suitable for the acute management of supraventricular tachycardia and the control of blood pressure and heart rate during surgery or other cardiac emergencies.

使用Esmolol hydrochloride is indicated for paroxysmal supraventricular tachycardia, the rapid control of ventricular rate in patients with atrial fibrillation or atrial flutter in perioperative, postoperative, or other emergent circumstances where short term control of ventricular rate with a short-acting agent is desirable. Esmolol hydrochloride is also indicated in noncompensatory sinus tachycardia where, in the physician's judgment, the rapid heart rate requires specific intervention. Esmolol hydrochloride is not intended for use in chronic settings where transfer to another agent is anticipated.

定義ChEBI: The hydrochloride salt of esmolol. A cardioselective and short-acting beta1 receptor blocker with rapid onset but lacking intrinsic sympathomimetic and membrane-stabilising properties, it is used in the management of su raventricular arrhythmias, and for the control of hypertension and tachycardia during surgery.
