Adrenaline (epinephrine) is a sympathomimetic agent that causes bronchodilatation. It is used to relieve bronchospasm in anaphylactic shock reactions.
Histamine, kinins and prostaglandins, such as prostaglandin E2, are inflammatory mediators. In response to allergic stimuli, inflammatory mediators may cause bronchoconstrictions.
