Q

Buspirone:

  • mechanism?
  • clinical use?
A
  • ->stimulates serotonin receptors

- ->used to treat GAD (no addiction, sedation, tolerance)

141
Q

TCA:

  • Mechanism?
  • Toxicity?
A
  • Mechanism: block reuptake of NE and Serotonin
  • Toxicity = Tri-C’s:
  • Convulsions
  • Coma
  • Cardiotoxicity (arrhythmias)
  • ->Also:
  • anticholinergic side effects; can lead to confusion and hallucinations in elderly
  • Sedation
142
Q

Treatment for CV toxicity from TCAs?

A

–>NaHCO3

143
Q

Which TCA should be used in elderly pts?

A

–>Nortryptiline (has fewer anti-cholinergic side effects, so better in elderly)

144
Q

Imipramine:

A

–>TCA that is used to treat bedwetting

145
Q

Clomipramine:

A

TCA used to treat OCD

146
Q

Doxepin

A

TCA (that doesn’t end in -typtyline or -ipramine!

147
Q

Amoxapine

A

TCA (that doesn’t end in -typtyline or -ipramine!

148
Q

SSRI that can be used to treat premature ejaculation?

A

Paroxetine

149
Q

List the SSRIs:

A
  • Fluoxetines
  • Paroxetine
  • Sertraline
  • Citalopram
150
Q

Toxicity of SSRIs:

A
  • sexual dysfunction –> anorgasmia (although Paroxetine can be used to treat premature ejaculation)
  • GI distress
  • Serotonin syndrome (hyperthermia, myoclonus, CV collapse, flushing, diarrhea, seizures)
151
Q

Serotonin syndrome:

  • cause?
  • presenation?
  • treatment?
A
  • ->When have too much serotonin; like if combine an SSRI and an MAO, so get lots of serotonin!
  • Presentation (think: lots of serotonin):
  • diarrhea
  • flushing
  • seizures
  • hyperthermia
  • myoclonus
  • CV collapse

*Treat with Cyproheptadine (an anti-histamine that is also a serotonin receptor blocker)

152
Q

Venlafaxine

A

SNRI

–>can be used to treat depression, GAD

153
Q

Duloxetine

A

SNRI
= “cimbalta”
–>treatment of depression, also can be used to treat diabetic peripheral neuropathy

154
Q

Tanylcypromaine

A

MAO inhibitor

155
Q

Phenelzine

A

MAO inhibitor

156
Q

Mechanism of MAO inhibitors:

A

–>increased levels of NE, Serotonin, Dopamine

157
Q

Selegiline

A

MAO inhibitor that is NOT used for depression; used to treat Parkinson’s

158
Q

Isocarboxazid

A

MAO inhibitor

159
Q

MAO inhibitors are contraindicated with:

A
  • foods with high tyramine content (wine, cheese, etc) –> b/c can get hypertensive crisis (b/c tyramine can act as a catecholamine, so get a whole ton of catecholamine release –> INCREASED BP!!!!)
  • Beta-agonists (can also lead to hypertensive crisis, b/c increased catecholamine action)
  • SSRIs (can lead to serotonin syndrome)
  • Meperidine (Opioid; can lead to serotonin syndrome)
160
Q

Buproprion:

A
  • atypical antidepressant
  • no sexual side effects
  • lowers seizure threshold (especially in bulemics, anorexics)
  • unknown mechanism, but leads to increased NE and dopamine
  • can be used for depression and also for smoking cessation
161
Q

Mirtazapine:

A
  • atypical antidepressant; good for depression with insomnia (b/c sedation = toxicity)
  • alpha -2-antagonist (so increases release of NE and serotonin) and serotonin-receptor antagonist
162
Q

Maprotiline:

A
  • atypical antidepressant
  • ->blocks NE reuptake
  • ->may cause orthostatic hypotension
163
Q

Trazodone:

A
  • atypical antidepressant
  • ->inhibits serotonin reuptake
  • ->used for insomnia (not really for depression, b/c need high doses for depression treatment)
  • toxicities:
  • postural hypotension
  • sedation (so can use for insomnia)
  • priapism –> “trazaBONE!”
