    Voorbeeldzinnen

    1. Noradrenaline (norepinephrine)
    2. In foals, noradrenaline is commonly the only catecholamine effective in treatment of hypotension.
    3. Noradrenaline acts primarily on alpha-1 receptors to vasoconstrict arterioles, thereby increasing blood pressure and maintaining central circulation.
    4. 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.
