ADRENACLICK vs ADRENALIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Epinephrine is a direct-acting sympathomimetic amine that acts on alpha- and beta-adrenergic receptors. Alpha-1 receptor activation causes vasoconstriction, increasing blood pressure and reducing mucosal edema. Beta-1 receptor activation increases heart rate and contractility. Beta-2 receptor activation causes bronchodilation and vasodilation.

100 to 200 mcg sublingually as needed for severe allergic reaction, may repeat every 5-15 minutes.
1 mg (1 mL of 1:1000 solution) intramuscularly or subcutaneously every 5-20 minutes as needed; for cardiac arrest: 1 mg intravenously or intraosseously every 3-5 minutes.

2.0-2.5 hours in adults with normal renal function; prolonged in renal impairment (up to 24 hours in anuria).
Approximately 2-3 minutes for the parent drug in plasma; clinical effects are short-lived due to rapid uptake and metabolism. In severe shock or hepatic impairment, half-life may be slightly prolonged.
Primarily renal (80-90% as unchanged drug via glomerular filtration and active tubular secretion), with 10-20% fecal via biliary elimination.
Primarily metabolized in the liver and other tissues by catechol-O-methyltransferase (COMT) and monoamine oxidase (MAO). Renal excretion of metabolites (metanephrine, vanillylmandelic acid) and unchanged drug (<2% as unchanged). Biliary/fecal excretion is minimal (<5%).
