Indications and Usage for Esmolol Injection

Esmolol Hydrochloride in Sodium Chloride Injection is indicated for 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 in Sodium Chloride Injection is also indicated in noncompensatory sinus tachycardia where, in the physician's judgment, the rapid heart rate requires specific intervention. Esmolol Hydrochloride in Sodium Chloride Injection is intended for short-term use.wisepoqder Esmolol

Intraoperative and Postoperative Tachycardia and Hypertension
Esmolol Hydrochloride in Sodium Chloride Injection is indicated for the short-term treatment of tachycardia and hypertension that occur during induction and tracheal intubation, during surgery, on emergence from anesthesia and in the postoperative period, when in the physician's judgment such specific intervention is considered indicated.
Esmolol hydrochloride in sodium chloride injection is administered by continuous intravenous infusion with or without a loading dose. Additional loading doses and/or titration of the maintenance infusion (step-wise dosing) may be necessary based on desired ventricular response.

In the absence of loading doses, continuous infusion of a single concentration of esmolol reaches pharmacokinetic and pharmacodynamic steady-state in about 30 minutes.

The effective maintenance dose for continuous and step-wise dosing is 50 to 200 mcg per kg per minute, although doses as low as 25 mcg per kg per minute have been adequate. Dosages greater than 200 mcg per kg per minute provide little added heart-rate lowering effect, and the rate of adverse reactions increases.
After patients achieve adequate control of the heart rate and a stable clinical status, transition to alternative antiarrhythmic drugs may be accomplished.

When transitioning from esmolol hydrochloride in sodium chloride injection to alternative drugs, the physician should carefully consider the labeling instructions of the alternative drug selected and reduce the dosage of esmolol hydrochloride in sodium chloride injection as follows:
Thirty minutes following the first dose of the alternative drug, reduce the esmolol hydrochloride in sodium chloride injection infusion rate by one-half (50%).
After administration of the second dose of the alternative drug, monitor the patient's response, and, if satisfactory control is maintained for the first hour, discontinue the esmolol hydrochloride in sodium chloride injection infusion.
Directions for Use
Esmolol hydrochloride in sodium chloride injection is available as a ready-to-infuse premixed solution in a single-dose flexible container bag. Esmolol hydrochloride in sodium chloride injection is not compatible with Sodium Bicarbonate (5%) solution (limited stability) or furosemide (precipitation).

Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit.
