Overview
Adrenalin (epinephrine in sodium chloride injection) is a sympathomimetic catecholamine. The chemical name of epinephrine is: 1,2- Benzenediol, 4-[(1R)-1-hydroxy-2-(methylamino)ethyl]-, or (-)-3,4-Dihydroxy-α-[2- (methylamino)ethyl]benzyl alcohol. The chemical structure of epinephrine is: The molecular weight of epinephrine is 183.2. Epinephrine solution deteriorates rapidly on exposure to air or light, turning pink from oxidation to adrenochrome and brown from the formation of melanin. Adrenalin (epinephrine in sodium chloride injection) is a clear, colorless, sterile solution administered by intravenous infusion, supplied in a 250 mL infusion bag. It is provided in five (5) ready-to-use concentrations containing: Ingredient Concentration 8 mcg/mL 16 mcg/mL 20 mcg/mL 32 mcg/mL 40 mcg/mL Epinephrine, USP 8 mcg 16 mcg 20 mcg 32 mcg 40 mcg Sodium chloride, USP 9 mg 9 mg 9 mg 9 mg 9 mg Disodium Edetate Dihydrate (EDTA), USP 10 mcg 10 mcg 10 mcg 10 mcg 10 mcg L (+) Tartaric Acid, NF 6.6 mcg 13.1 mcg 16.4 mcg 26.2 mcg 32.8 mcg It may contain hydrochloric acid and/or sodium hydroxide for pH adjustment. It has a pH range of 3.7 - 4.3. The headspace in the containers has been displaced with nitrogen gas. chemical structure
Indications & Usage
Adrenalin ® is a non-selective alpha and beta adrenergic agonist indicated to: Increase mean arterial blood pressure in adult patients with hypotension associated with septic shock ( 1.1 ) 1.1. Hypotension associated with Septic Shock Adrenalin is indicated to increase mean arterial blood pressure in adult patients with hypotension associated with septic shock.
Dosage & Administration
No further dilution prior to infusion is required ( 2.1 ) Infuse epinephrine into a large vein ( 2.2 ) Titrate 0.05 mcg/kg/min to 2 mcg/kg/min to achieve desired blood pressure ( 2.2 ) Wean gradually ( 2.2 ) See Full Prescribing Information for instructions on administration of the injection. 2.1. General Considerations Administration Adrenalin is a ready to administer product that requires no further dilution prior to infusion. Inspect visually for particulate matter and discoloration prior to administration; solution should be clear and colorless. Do not use if the solution is colored or cloudy, or if it contains particulate matter. Do not open the aluminum overwrap until time of use. The premixed, ready-to-use infusion bag has a single port for insertion of the infusion set only. This port should not be used to remove content from the bag or add another medication. Once the infusion bag has been connected to the infusion set, it is stable for 24 hours, as long as the bag stays connected to the infusion set. Single dose only. Discontinuation When discontinuing the infusion, reduce the flow rate gradually. Avoid abrupt withdrawal. Discard unused portion. 2.2. Hypotension associated with Septic Shock Whenever possible, give infusions of epinephrine into a large vein. Avoid using a catheter tie-in technique, because the obstruction to blood flow around the tubing may cause stasis and increased local concentration of the drug. Avoid the veins of the leg in elderly patients or in those suffering from occlusive vascular diseases. To provide hemodynamic support in septic shock associated hypotension in adult patients, the suggested dosing infusion rate of intravenously administered epinephrine is 0.05 mcg/kg/min to 2 mcg/kg/min and is titrated to achieve a desired mean arterial pressure (MAP). The dosage may be adjusted periodically, such as every 10 to 15 minutes, in increments of 0.05 mcg/kg/min to 0.2 mcg/kg/min, to achieve the desired blood pressure goal. After hemodynamic stabilization, wean incrementally over time, such as by decreasing doses of epinephrine every 10 minutes to determine if the patient can tolerate gradual withdrawal.
Warnings & Precautions
Monitor blood pressure frequently ( 5.1 ) Increases cardiac output and causes peripheral vasoconstriction ( 5.2 ) May induce cardiac arrhythmias and myocardial ischemia. ( 5.3 ) Avoid extravasation into tissues, which can cause local necrosis ( 5.4 ) May aggravate angina pectoris or produce ventricular arrhythmias ( 5.5 ) Constricts Renal blood vessels which may result in oliguria or renal impairment ( 5.5 ) 5.1. Hypertension Because individual response to epinephrine may vary significantly, monitor blood pressure frequently and titrate to avoid excessive increases in blood pressure. Patients receiving monoamine oxidase inhibitors (MAOI) or antidepressants of the triptyline or imipramine types may experience severe, prolonged hypertension when given epinephrine. 5.2. Pulmonary Edema Epinephrine increases cardiac output and causes peripheral vasoconstriction, which may result in pulmonary edema. 5.3. Cardiac Arrhythmias and Ischemia Epinephrine may induce cardiac arrhythmias and myocardial ischemia in patients, especially patients suffering from coronary artery disease, or cardiomyopathy. 5.4. Extravasation and Tissue Necrosis with Intravenous Infusion Avoid extravasation of epinephrine into the tissues, to prevent local necrosis. When Adrenalin is administered intravenously, check the infusion site frequently for free flow. Blanching along the course of the infused vein, sometimes without obvious extravasation, may be attributed to vasa vasorum constriction with increased permeability of the vein wall, permitting some leakage. This also may progress on rare occasions to superficial slough. Hence, if blanching occurs, consider changing the infusion site at intervals to allow the effects of local vasoconstriction to subside. There is potential for gangrene in a lower extremity when infusions of catecholamine are given in an ankle vein. Antidote for Extravasation Ischemia : To prevent sloughing and necrosis in areas in which extravasation has taken place, infiltrate the area with 10 mL to 15 mL of saline solution containing from 5 mg to 10 mg of phentolamine , an adrenergic blocking agent. Use a syringe with a fine hypodermic needle, with the solution being infiltrated liberally throughout the area, which is easily identified by its cold, hard, and pallid appearance. Sympathetic blockade with phentolamine causes immediate and conspicuous local hyperemic changes if the area is infiltrated within 12 hours. 5.5. Renal Impairment Epinephrine constricts renal blood vessels, which may result in oliguria or renal impairment.

Adverse Reactions
The following adverse reactions are discussed elsewhere in labeling: Hypertension [see Warnings and Precautions ( 5.1 )] Pulmonary Edema [see Warnings and Precautions ( 5.2 )] Cardiac Arrhythmias and Ischemia [see Warnings and Precautions ( 5.3 )] Extravasation and Tissue Necrosis with Intravenous Infusion [see Warnings and Precautions ( 5.4 )] Renal Impairment [see Warnings and Precautions ( 5.5 )] The following adverse reactions associated with the infusion of epinephrine were identified in the literature.
