13 Cards in this Set

  • Front
  • Back
Acetylcholine
Muscarinic and nicotinic receptor agonist. Muscarinic effects predominate.

Lower BP
Carbachol
Muscarinic and nicotinic receptor agonist. Muscarinic effects predominate. Not metabolized by AChE.

Lower BP
Carotid Occlusion
Stimulates baroreceptors in carotid artery to activate sympathetic system. Causes release of NE and Epi.

Raise BP
DMPP (Dimethylphenylpiperazinium)
Nicotinic receptor agonist. Relatively selective for for release of catecholamines from adrenal medulla.

Raise BP
Epinephrine
Alpha and beta agonist. Alpha effects predominate, although affinity for beta receptors is somewhat greater than affinity for alpha receptors.

Raise BP
Histamine
H1 and H2 receptor agonist. H1 is fast-acting and H2 is slower-acting and has longer duration of action. Both cause vasodilation.

Lower BP
Isoprateranol
Beta selective agonist.

Lower BP.
McN-A-343
Muscarinic agonist with affinity for M1 receptors on nerves. Causes activation of sympathetic system (release of NE).

Has lower affinity for M3 receptors on endothelium, which cause vasodilation.

Predominant effect: Raise BP
NE
Alpha and beta1 agonist. Alpha effects predominate.

Raise BP
Phenylephrine
Selective alpha agonist.

Raise BP
Pilocarpine
Plant-derived muscarinic agent.

Lower BP
Tyramine
Indirect sympathomimetic that is taken up into SN terminals and causes release of NE from Tyramine Reusable Pool. Blocked by drugs like cocaine or impramine.

Raise BP
Vagal stimulation
Stimulation of vagus nerve causes release of ACh on muscarinic receptors of supraventricular cells of heart, slowing or stopping the heart.

Lower BP
