Reuptake Inhibitors of NE

Blocks release of NE

These receptors inhibit NE release. What receptor stimulates secretion?
alpha 2, Muscarinic 2

Angiotensin II receptor
What substance do you not take when you're taking MAOI's?
Tyramine(dietary) will stimulate release of NE. MAO is also in gut, which normally breaks down Tyramine. But due to MAOI, it is NOT broken down and causes hypertensive crisis.
Byproducts of breakdown of NE
VMA, Metanephrines, Normetanephrines
beta 2 stimulation
vasodilation and bronchodilation, also heart rate increase, increased contractility

V2 stimulation
increase H2O permeability in kidney

V2 is found in 2 kidneys
Phase I metabolism
more polar

reduction, oxidation, hydrolysis
Phase II metabolism
very polar, inactive metabolites, renally excreted

acetylation, glucuronidation, sulfation

Acute Asthma. Long term treatment?
Metaproterenol, Albuterol

Long term - Salmeterol
Premature Uterine Contractions
Terbutaline, Ritodrine
Uptake inhibitors
Cocaine, TCA, Amphetamine
Stimulates release of NE
Ephedrine, Amphetamines, Tyramine
Heart rate response to NE?
reflex bradycardia
Heart rate response to Isoproterenol?
Reflex tachycardia

beta 1 -- increases heart rate
beta 2 -- vasodilates
alpha 2 agonists
clonidine, alpha methyldopa
What side effect does Clonidine have?
rebound hypertension if a dose is missed...
What is a notable use of alpha methyldopa?
maintain BP in pregnancy
Notable about levalbuterol?
Does NOT have beta 1 effects, so can give to people with heart failure
beta blockers that treat MI?
Metoprolol, Carvedilol
glaucoma beta blocker
timolol
Cocaine overdose. Response to beta blockers?
BAD, will cause hypertensive crisis.

Cocaine causes noradrenergic stimulation of all alpha AND beta. Beta 2 vasodilation mediates the crisis. But with beta blockers will then cause unopposed alpha stimulation.
Open angle glaucoma(wide angle)
obstructed OUTFLOW(canal of Schlemm)

common, insidious, loss of peripheral vision
Closed angle glaucoma(narrow angle)
abrupt, painful, lens sticks to iris. pupil NOT reactive to light

EMERGENCY
What is contraindicated in closed angle glaucoma?
