Cardio: Alpha/Beta Receptor Agonists Flashcards
- The left column is tissues and the right column is the effects of receptor activation on that tissue.
- What receptor is associated with these tissues and effects?
β1
What is the receptor selectivity and general effects of Norepinephrine?
What is the clinical application for it?
What are the clinical applications for non-selective β agonists?
What are the general effects of α2 agonists?
What are the general clinical applications for catecholamines?
What are the general Clinical Applications for α2 Agonists?
- Stimulating α2 Receptors Inhibits Sympathetic Nervous System Tone
- Treatment of hypertension
What is the receptor selectivity and general effects of Dopamine?
What is ⍺-Methyldopa?
α2 Selective Agonist
(Prodrug, decarboxylated to a-methylnorepinephrine)
What are the sympathetic receptor agonist mnemonics?
METH and OXY increase DOPAmine, DOUBle time. Insane
- Methoxyamine: α1 selective agonist
- ⍺-Methyldopa: α2 selective agonist
- Dobutamine: β1 selective agonists
- Isoproterenol: Nonselective β agonists
