Epinephrine Administered in Anaphylaxis: The Evolution of 0.3 mg Dosage

Background:
Despite epinephrine's historical use for over a century and Food and Drug Administration (FDA) approval for EpiPen's use in 1987 to treat anaphylaxis, little information exists regarding selection of the 0.3 mg adult dose. A review of literature was conducted to provide a historical retrospective regarding the evolution of the dosage selected for today's EpiPen. The first adrenal gland extract, isolation of the epinephrine active ingredient, observation of physiological effect, selection of the intramuscular route for administration, the dosage range recommended by independent physicians based on their clinical observations and selection of the ultimate standardized dosage are profiled.
Conclusion:
This retrospective review illustrates the drug development process prior to the rigors required for today's clinical trials and provides clinical evidence supporting the dose in EpiPen and other similar life-saving epinephrine products.

Adrenergic Agonists: Therapeutic Uses
Emergency and Intensive Care Unit (ICU) applications: Pressor agents increase blood pressure, heart rate, and contractility in shock and organ failure situations. Dopamine can induce vasodilation and stimulate adrenoceptors. Endogenous catecholamines are effective in treating cardiogenic shock. α2-agonists like clonidine can reverse anesthesia-induced hypertension.

Adrenergic Receptors: β Subtype
Isoprenaline > Adrenaline > Noradrenaline
Neurotransmitter binding to these receptors causes activation of adenylyl cyclase resulting in increased concentrations of cAMP and modulation of calcium ion channels within the cell. They are further classified into β1, β2, and β3 subtypes.

Adrenergic Agonists: Mixed-Action Agents
Ephedrine and pseudoephedrine lack a catecholamine group, making them less susceptible to degradation by metabolic enzymes. They have increased oral bioavailability and lipophilicity, resulting in a longer duration of action. Their response is reduced by...
