atropine
|
antagonist muscarinic receptors affecting the parasympathetic nervous system
|
useful for dangerously low heart rate
|
|
metoprolol
|
beta-1 adrenergic receptor antagonist affecting the sympathetic nervous system
|
useful for blood pressure, protective effect after heart attacks
|
|
succinylcholine
|
depolarizes NMJ, causing spastic paralysis - Tx prior to surgery
|
Cholinomimetic
Mimics Ach in the motor system - binds N1 |
|
bethanechol
|
to treat 'lazy gut'; causes GI and bladder contraction
|
Cholinomimetic
Mimics Ach in the parasympathetic system, specifically gut |
|
Physostigmine
|
Acetycholine esterase inhibitor
|
Crosses blood brain barrier
Used to treat atropine OD |
|
Organophosphates (ex Parathion)
|
Irreversible acetylcholine esterase inhibitor
|
Nerve gas
Rodent poison TREAT with atropine and Pralidoxine |
|
Pralidoxine
|
treat organophosphate poisoning
|
|
|
Carbidopa
|
Blocks decarboxylation of dopa to dopamine
|
Cannot cross blood brain barrier to prevents overproduction of dopamine, epi, and NE in rest of body when delivering L-dopa to parkinson's patients
|
|
Tricyclics
|
block reuptake of NE, serotonin
|
anti-depressant
|
|
SSRIs
|
block reuptake of serotonin
|
anti-depressant
|
|
amphetamine
|
blocks reuptake of NE/E
|
Catecholaminomimetics (sympathomimetic)
|
|
cocaine
|
blocks reuptake of NE/E
|
Catecholaminomimetics (sympathomimetic)
|
|
ephedrine
|
Blocks reuptake of NE/E/Ser
Works similarly to tri-cyclic antidepressants |
Catecholaminomimetics
|
|
MAOi
|
Catecholaminomimetics - blocks the breakdown of NE in the cytoplasm after reuptake, increasing its concentration
|
Do not give with false transmitter. leads to excess NE in cleft and hypertensive crisis
|
|
Clonidine
|
alpha-2-receptor agonist
|
reduce hypertension by preventing release of NE/E
But reduction of release of NE/E in brain will make depression worse in depressed patients, contraindication Sympatholytic |
|
Sympathomimetic
|
stimultes post-synaptic excitatory alpha receptors only, will not bind pre-synaptic inhibitory alpha receptors
|
|
|
Albuterol
|
beta-2 agonist
|
bronchodilator in asthma
|
|
Dopamine
|
D1=D2>Beta-2>Beta1>alpha agonist
|
congestive heart failure - beta-1 agonist to force the heart to keep moving the blooding
|
|
Dobutamine
|
Beta-1>Beta-2 agonist
|
congestive heart failure- beta-1 agonist to force the heart to keep moving the blooding
|
|
Atenolol
|
beta-1 antagonist
|
post-MI protection to reduce stress on heart
|
|
Lobetalol
|
alpha-1>beta-1 antagonist
|
control hypertension
|
|
Propranolol
|
beta-1=beta-2 antagonist
|
control hypertension, but cannot use in an asthmatic patient
|
|
Ergot alkaloids
|
serotonin mimickers
Peripheral vasoconstrictors CNS stimulators ("convulsive ergotism") |
Like being treated with LSD
|
|
Bromocriptine maleate
|
serotonin agonist
parkinsonism gynecomastia |
|
|
Melatonin
|
serotonin agonist
resets biological sleep clock |
|
|
Ergonovine maleate
|
serotonin agonist
stop postpartum bleeding by inducing oxytoxic effects |
|
