Epinephrine

Overview

Epinephrine, commonly known by brand names such as Adrenalin and EpiPen, is a critical medication used in veterinary medicine for emergency situations. It is a sympathomimetic drug primarily used to treat severe allergic reactions and cardiac arrest in pets.

How It Works

Epinephrine works by stimulating alpha and beta-adrenergic receptors in the body, which leads to vasoconstriction, increased heart rate, and bronchodilation. This helps to quickly counteract life-threatening symptoms during anaphylactic reactions and cardiac events.

• Severe allergic reactions (anaphylaxis)
• Cardiac arrest
• Asthma attacks (in some cases)
