55
Q

  • due to D2 blockade via haloperidol.
  • rigidity, myoglobinuria, autonomic instability, hyperpyrexia.
  • dantrolene, D2 agonists (e.g., bromocriptine)
  • so in this case you can give D2 agonists - but you dont give D2 agonists for the extra-pyramidal side effects.
58

Antipsychotics: high potency

  • neuro (EPS) side effects or non-neuro?
  • why?
A
  • primarily neuro side effects aka EPS, due to potent D2 antagonism.
  • they’re very potent so you dont have to give a lot which means the extra-neuro side effects will be minimal.
  • if you gave a much higher dose than was required im sure you’d get some extra-neuro side effects as well.
63
Q

Antipsychotics: low potency

  • neuro (EPS) side effects or non-neuro?

Lithium is VERY similar to Na! This can depolarize

cells and produce tremors.

88

-TSH binds to Gs coupled receptors on thyroid but
lithium dec. cAMP so prevents action of TSH.
-Lithium also = peripheral deiodinase inhibitor.
-hypothyroidism can cause depression.

89
Q

How does lithium cause depression?

A

-TSH binds to Gs coupled receptors on thyroid but
lithium dec. cAMP so prevents action of TSH.

Its metabolite is a dopamine antagonist so can lead to too much prolactin & subsequent side effects of that.

120
Q

TCAs

-how do they lead to arrythmias?

A
  • cardiac fast Na channels blocked.
  • phase 0 prolonged = QRS prolonged.
  • this also have negative inotropic effects bc you have impaired excitation-contraction coupling w/diminished release of Ca from SR. Remember - the influx of Na & resultant depolarization is what causes the Ca channels to open. So this is being screwed up.

*combine this neg. inotropy w/alpha-1 blockade & you have refratory hypotension.

121
Q

TCA

-how do they get refractory hypotension?

A

dec. inotropy + alpha-1 blockade.

122
