Psychopharmacology
For mania Lithium carbonate Anticonvulsants Antipsychotics Anxiolytics
For depressive phase
Use antidepressants with care (may trigger mania).
Lithium
First choice of treatment!!!
effective in 7-14 days
very narrow therapeutic index, must keep blood levels between 0.4-1.3mEq/L
Requires frequent labs that must be drawn 8-12hrs after last dose given. Once therapeutic level reached blood levels drawn every month for a period of time, then every three months.
Side effects of lithium
expected common side effects are fine hand tremor and weight gain
Toxicty occurs w levels over 1.5mEq/L–> tremor increase, nausea, vomiting, confusion, seizures, coma, hypotension, loss of bodily movements
Treatment: discontinuation of the drug, IV fluids, emetic meds, possibly hemodialysis
lithium long term risks
hypothyroidism and kidney impairment
lithium teaching
Lithium decreases sodium reabsorption in the kidneys which can lead to sodium deficiency. Decreased sodium can lead to lithium retention and toxicity
Anticonvulsants
Depakote
Lamictal
Tegretol
Diminishes impulsive and aggressive behaviors.
Depakote
Used for lithium non-responders who are in acute mania and rapid cycling. Effective in the treatment of both acute mania and bipolar depression. Monitor liver (AST & ALT), depakote level, and platelet counts.
Lamictal
Very effective 1st line treatment used for bipolar depression. Serious reaction is life threatening rash (Steven’s Johnson).
Tegretol
Used in treatment resistant bipolar disorder often in combination with Lithium an antipsychotic drug. Works well in patients whose mania is angry and paranoid. Also good for bipolar depression. Monitor liver and platelet counts and beware of possible bone marrow suppression or liver inflammation.
