D1 receptor - Guides d'étude, Notes de cours & Résumés

Which of the following agents has a pure beta agonist effect in the circulation? 1. Isoprenaline 2. Dopamine 3. Adrenaline 4. Noradrenaline - ANSWER 1. Isoprenaline Isoprenaline is a pure β-receptor agonist and a potent vasodilator. Dopamine acts on D1 receptors (vasodilation) at higher doses it affects α- and β-receptors. Adrenaline acts on β1, β2 and α1 receptors depending on the dose. Noradrenalin is a potent α- and β1-receptor agonist.
