|
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 |
