Clinical instructions clearly state that for pharmacological reasons, amiodarone injection can only be prepared using isotonic glucose solution and do not add any other preparation to the infusion, therefore amiodarone cannot be prepared in saline. Because Amiodarone is a diiodine substituent on the benzene ring, iodine substituents are generally unstable and prone to degradation by spontaneous deiodination, and an acidic environment can inhibit the degradation of Amiodarone, while glucose solution is acidic and saline is neutral, and chloride ions in saline can replace iodine on the benzene ring and produce precipitation. If prepared with saline, precipitates may be seen, which may have serious consequences when injected intravenously, therefore, amiodarone injection will not be prepared with saline in clinical use. Amiodarone belongs to the third class of antiarrhythmic drugs, which is a relatively broad-spectrum antiarrhythmic drug. It should be noted that some adverse reactions may occur during use, and if there is any discomfort during the infusion, contact the doctor immediately.
