Q

Bupropion MOA

A

weakly inhibits reuptake of dopamine and NE, may promote release of dopamine and NE

30
Q

Antidepressant that can be used for smoking cessation and obesity

A

Bupropion (Wellbutrin)

31
Q

How are Bupropion ADRs different than other antidepressants?

A

fewer ADRs for sexual dysfunction or withdrawal symptoms (can stop abruptly)

still has suicide risk, tachycardia, weight loss, GI, CNS, cardio…

32
Q

Antidepressant that may be used to treat insomnia

33
Q

Indication of low dose benzodiazepines

anti-anxiey

34
Q

Meds in Benzodiazepine class?

Diazepam (Valium), Lorazepam (Ativan), Midazolam (Versed)

35
Q

What are best uses of diazepam and lorazepam? Why?

A

diazepam has long half-life (15-20 hrs) so best for anxiety

lorazepam shorter half-life so better for insomnia

36
