Voorbeeldzinnen
- Noradrenaline (norepinephrine)
- In foals, noradrenaline is commonly the only catecholamine effective in treatment of hypotension.
- Noradrenaline acts primarily on alpha-1 receptors to vasoconstrict arterioles, thereby increasing blood pressure and maintaining central circulation.
- Hence ephedrine, which causes noradrenaline release at the nerve endings, thereby increasing cardiac contractility and obtunding hypotension, is used when dobutamine and dopamine are ineffective.
