6 Lithium Mood stabilizer- acute mania and maintenance, schizoaffective Excreted via the kidney MOA unknown 1-3 for antimanic effects (so use with benzo, antipsychotic, Depakote if needed) Decreases suicide risk Narrow therapeutic window, needs blood levels checked Lithium Dietary sodium decreases lithium Dehydration increases lithium Toxicity! stop Li! Rehydrate, may need dialysis GI upset, weight gain, sedation, tremor, polyuria, polydipsia Hypothyroidism! tx with levothyroxine (Synthroid) Teratogenic: Ebstein!s anomoly Valproate (Depakote, Depakene) Mood stabilizer- acute mania and maintenance, schizoaffective Anxiolytic and antiaggressive Preferred for acute mania in kids and elderly GI, increased LFTs, sedation, weight gain, hair loss, pancreatitis PCOS Neural tube defects (folate mvi) Carbamazepine (Tegretol) Anticonvulsant- FDA approval for acute mania, mixed Better tolerated, usually no weight gain Bid dosing GI and CNS side effects Agranulocytosis (depress bone marrow) Induces metabolism of itself/other drugs so tell this to patients on OCP or!

7 Other things to consider Atypical Antipsychotics Psychotherapy CCB (Verapamil) Antidepressants! Typical Antipsychotics Tx psychosis haloperidol* (Haldol), fluphenazine* (Prolixin), trifluoperazine (Stelazine), chlorpromazine (Thorazine) High affinity D2 receptor antagonism! greater EPS NMS = lead pipe rigidity, fever, autonomic instability, decreased consciousness, elevated CPK Lower the seizure threshold Atypical Antipsychotics Tx psychosis, some adjunctive indications Risperidone (Risperdal), olanzapine (Zyprexa), quetiapine (Seroquel), ziprasidone (Geodon), aripiprazole (Abilify), clozapine (Clozaril) 5HT2 > D2 receptor blockade compared to typicals. Less EPS All have more weight gain and glucose abnormalities Atypical Antipsychotics risperidone* (Risperdal)- hyperprolactinemia olanzapine (Zyprexa)- weight gain quetiapine (Seroquel)- sedation, low EPS ziprasidone (Geodon)- orthostatic hypotention aripiprazole (Abilify)- partial agonist at D2, akathisia clozapine (Clozaril)- sedation, weight gain, no effect on prolactin, no EPS or TD BUT Agranulocytosis, needs registry

8 Know drug classes My Advice Differentiate disease by big picture (more mood symptoms? More psychotic symptoms?) If objectives are given in a lecture, be able to answer those objectives. And for Step 1 questions, questions, questions.
