Class: Sympathomimetic
Me. Mechanism of Action: Epinephrine stimulates alpha-1 (α-1) (heart) and beta1 and beta 2 (β-1 and β-2) (lungs) receptors. Because of these effects the drug causes: peripheral vasoconstriction (α); increased heart rate, contraction force (β1); and bronchodilation (β2). Inhibits mast cell degranulation (immune system response)
Onset: 6-15 minutes IM
Indications: Anaphylaxis
Contraindications: None when used in emergency situations
Side Effects: Increased myocardial oxygen demand, ischemia, tachydysrhythmias, and anxiety
Dosage: 0.3 mg IM (1:1000) repeated as needed
