What is the mechanism of action of typical antipsychotics?
blocks D2 receptors

During the first 1-2 weeks.
How lon gdoes it take for antidepressants to start working?
2-4 weeks
What is Serotonin toxicity?

What are the symptoms of Serotonin toxicity?
hyperthermia, myoclonus, mental state changes
What are the symptoms of muscarinic blockade?
anti-SLUD (salivation, lacrimation, urination, defecation)
What is the main symptom of alpha-1 blockade?
orthostatic hypotension
What is the pharamcology of TCAs?
non-selective reuptake inhibitor of NA and 5HT
what are the side effects of lithium?
hypothyroidism
diabetes insipidus (due to decreased response to ADH)
fine tremor

other: sexual dysfunction, SADH, bleeding risk, decreased BMD
What are the side effects of TCAs?
- anti-SLUD
- orthostatic hypotension
- sedation
- prolonged QT interval
