PRESCRIBING INFORMATION EPINEPHRINE INJECTION USP 1 mg / mL Sterile Solution For Intramuscular (IM), Intravenous (IV), Intratracheal (IT) or Subcutaneous (SC) Use SYMPATHOMIMETIC Hikma Canada Limited 5995 Avebury Road, Suite 804 Mississauga, Ontario L5R 3P9 DATE OF PREPARATION: April 19, 2022 CONTROL NO: 262620 2 NAME OF DRUG EPINEPHRINE INJECTION USP Sterile Solution THERAPEUTIC CLASSIFICATION SYMPATHOMIMETIC EPINEPHRINE INJECTION USP is a parenteral adrenergic (sympathomimetic) agent and cardiac stimulant. ACTION AND CLINICAL PHARMACOLOGY The actions of epinephrine resemble the effects of stimulation of adrenergic nerves. It acts on both alpha and beta receptor sites of sympathetic effector cells. Its most prominent actions are on the beta receptors of the heart, vascular and other smooth muscle. When given by rapid intravenous injection, it produces a rapid rise in blood pressure, mainly systolic, by (1) direct stimulation of cardiac muscle which increases the strength of ventricular contraction, (2) increasing the heart rate and (3) constriction of the arterioles in the skin, mucosa and splanchnic areas of the circulation. When given by slow intravenous injection, epinephrine usually produces only a moderate rise in systolic and a fall in diastolic pressure. Although some increase in pulse pressure occurs, there is usually no great elevation in mean blood pressure. Accordingly, the compensatory reflex mechanisms that come into play with a pronounced increase in blood pressure do not antagonize the direct cardiac actions of epinephrine as much as with catecholamines that have a predominant action on alpha receptors. Total peripheral resistance decreases by action of epinephrine on beta receptors of the skeletal muscle vasculature and blood flow is thereby enhanced. Usually this vasodilator effect of the drug on the circulation predominates so that the modest rise in systolic pressure which follows slow injection or absorption is mainly the result of direct cardiac stimulation and increase in cardiac output.
