What medical conditions can cause mania?
CNS Disorders
Electrolyte/Metabolic abnormalities
Endocrine disregulation
How do you design a pharmacotherapy plan for mania?
Lithium or Valproic acid + Benzodiazepine (Lorazepam)
Add an atypical anti-psychotic if the patient is psychotic
What are some other alternatives to Lithium and Valproic Acid?
Which anti-psychotic can you choose if the patient is psychotic?
Olanzapine 10 mg QHS
What is the dose, as well as the acute and maintenance serum levels for lithium?
300 mg Tid

acute mania: 1.0-1.2 mEq/L
maintenance : 0.6-1.2 mEq/L
What is the starting dose for Valproic acid? What is the serum therapeutic range?
250 mg Tid

50-125 mcg/ml
What is the dose for Lorazepam?
2-40 mg/day QHS
As the patient becomes less psychotic, taper off the anti-psychotic. If the patient is in the depressed state, substitute the antipsychotic with an anti-depressant.

Renal function
Lithium levels
If a patient presented with bipolar disorder, needed lithium and had comorbid hypertension, what would you be your agent of choice?

Thiazide diuretics and ACE's/ARB's increase lithium levels
What is important to counsel a patient on if they are taking lithium?
Drink extra fluids when you are sweating and do no go on a sodium restricted diet without consulting your doctor. (Na, Li compete for reabsorption in the proximal tubule. Decreased Na leads to increase Li reabsorption and increased Li levels.)
In someone taking lithium, what otc painreliever would you recommend?
Aspirin or Acetaminophen are okay
Advil is not okay (NSAIDs increase Lithium levels)
If a patient reports diarrhea, you would be concerned about dehydration and increased lithium levels. What would you tell the patient?

Use EE 50 mcg and a 2nd method of contraception

Erythromycin - Inhibit 3A4 isozyme
Other drugs that inhibit 3A4: Azoles, Isoniazid CCBs, Fluoxetine, Fluvoxamine, Ritonavir

Valproic acid (divalproex) can cause elevated serum ammonia levels, which can present in a worst case scenario as seizures with foaming at the mouth. The patient can also present with excessive sedation, confusion and disorientation
