|
An important vasodilator in renal blood vessels
|
Dopamine
|
|
|
The rate limiting step of dopamine and tyrosine is
|
Tyrosine hydroxlase
Tyrosine -----> DOPA |
|
|
Inhibition of Vesicle transport for NE and Dopamine
|
Reserpine
|
|
|
Metyrosine MOA
|
Inhibits tyrosine hydroxylase thus preventing formation of NE and Dopamine

|
|
|
Termination of NE and Dopamine go thru
|
Diffusion or Reuptake
Especially reuptake |
|
|
Metabolism of NE and Dopamine in cleft is via
|
COMT, cathecol-Omethyltransferase
and MAO, Monoamine Oxidase |
|
|
Guanethidine MOA
|
Blocks NE or Dopamine release from presynaptic
|
|
|
Cocaine/TCA MOA
|
Blocks reuptake of NE
|
|
|
The resting heart rate and pupil are under the control of
|
Parasympathetic ANS
|
|
|
If ANS blockade occurs what affect would see on the eyes and heart?
|
Removal of the dominant PANS and nondominant SANS results in
