Drug Affects
Drugs Afffection the Sympathetic Nervous System
| Question | Answer |
|---|---|
| Alpha-1 Adrenergic receptors | receptor located on smooth muscle that mediates smooth muscle contraction |
| Alpha-2 Adrenergic receptors | receptor located on adrenergic nerve endings that reduces the release of NE |
| Beta-Adrenergic receptors | Found on cardiac and some smooth muscle |
| beta-1 receptors | prodominant beta-receptors of the heart |
| beta-2 receptors | predominant beta-receptors of smooth muscle of some organs and tissues |
| sympatholytics | action of an adrenergic drug or action that increases sympathetic activity |
| alpha-adrenergic drugs | drug that stimulates the alpha adrenergic receptors |
| selective beta-2 adrenergic drugs | drug that stimulates on beta-2 receptors at therapeutic doses |
| alpha-1 adrenergic blockers | Drug that block the alpha-1 effects of NE and EPI |
| nonselective beta-adrenergic blockers | drug that stimulates both beta-1 and beta-2 receptors |
| selective beta-1 adrenergic blockers | drug that blocks only beta-1 receptors |
| adrenergic neuronal blockers | reduces the formation or rlease of NE by acting at the neruronal nerve endings |
