1
Q
Alpha Adrenergic Agonists
[Primary Action]
A
- Contraction of smooth muscle
- Vasoconstriction = increasing BP and improving circulation; nasal decongestant
- Contraction of GI sphincters = appetite suppressant
- Contraction of urinary sphincters
- Dilation of pupils (mydriasis) = ocular decongestant
2
Q
Alpha Adrenergic Agonists
[Indications]
A
- Hypotensive states
- Nasal congestion
- Ocular congestion / testing
- Eating disorders (over eating)
3
Q
Beta Adrenergic Agonists
[Primary Action]
A
- Cardiac stimulation
- Bronchiole smooth muscle relaxant
- Uterine smooth muscle relaxant
4
Q
Beta Adrenergic Agonists
[Indications]
A
- Bronchoconstriction = epi + B2
- Hypotension = epi
- Cardiac insufficiency = epi + B1
5
Q
Alpha Adrenergic Agonists
[Examples]
A
- Norepinephrine = Levophed
- Tetrahydrozoline = Visine
- Tetrahydrozoline = Tyzine
6
Q
Beta Adrenergic Agonists
[Examples]
A
- Epinephrine = Adrenaline
- Isoproterenol = Isuprel
- Salmeterol = Serevent
7
Q
Tricyclic Antidepressants (TCAs) [Primary Action]
A
- Exact mechanism unknown; blocks reuptake of 5HT and NE; allows for longer action of NTs at synaptic cleft and helps alleviate some symptoms of depression
8
Q
Tricyclic Antidepressants (TCAs) [Indications]
A
- Treatment of depression
9
Q
Monoamine Oxidase Inhibitors (MAOIs)
[Primary Action]
A
- Prevent the breakdown of NE and 5HT in Adrenergic synapses; increase the amount of NTs available to work in brain
10
Q
Monoamine Oxidase Inhibitors (MAOIs)
[Indications]
A
- Treatment of depression
11
Q
Tricyclic Antidepressants (TCAs) [Adverse Effects]
A
- Anticholinergic effects
- Excessive stimulation of the CNS
- T wave and ST segment alteration (may lead to arrhythmias)
- Obstructive jaundice
12
Q
Selective Serotonin Reuptake Inhibitors (SSRIs)
[Primary Action]
A
- Selectively blocks reuptake of 5HT; allows for longer action at synaptic cleft and helps alleviate symptoms of depression
13
Q
Selective Serotonin Reuptake Inhibitors (SSRIs)
[Examples]
A
- Fluxetine = Prozac
14
Q
Antiepileptics
[Examples]
A
- Carbamazepine (Tegretol)
- Phenobarbital (Luminal)
- Phenytoin (Dilantin)
- Clonazepam (Klonopin)
- Diazepam (Valium)
- Valporic Acid (Depakene)
15
Q
Barbiturates
[Primary Actions]
A
- Increases inhibitory effects of GABA within the CNS making irritable neurons much less likely to fire
16
Q
Barbiturates
[Indications]
A
- Used in the treatment of partial seizures and tonic-clinic seizures
17
Q
Barbiturates
[Examples]
A
- Phenytoin (Dilantin)
18
Q
Benzodiazepines
[Pharmacology]
A
- Enhances inhibitory role of GABA in the cerebral cortex, spinal cord, limbic system and reticular formation by increasing influx of chloride into cells leading to hyperpolarization (lower membrane potential)
19
Q
Benzodiazepines
[Primary Actions]
A
- Limbic system = decreases anxiety
- Reticular formation = sedation and hypnosis
- Cerebral cortex = anticonvulsant
- Spinal cord = decreases skeletal muscle tone
20
Q
Benzodiazepines
[Examples]
A
- Diazepam (Valium)
- Midazolam (Versed)
- Lorazepam (Ativan)
21
Q
Opioids
[Primary Actions]
A
- Stimulates mu and kappa receptors inhibiting the release of substance P (NT) therefor reducing nociceptor information sent from periphery to CNS
22
Q
Opioids
[Indications]
A
- Relief for moderate to severe acute and chronic pain (typically associated with MI, back/head/neck injury, cancer or chronic unidentified pain)
- Preoperative sedation
- Cough suppression
- Diarrhea
- Anxiety
