Meds Mood Stabilizers Antipsychotics Lamotrigine – for depression only + SSRIs (usually with a mood stabilizer or anti-
psychotic)
Psychotherapy Case Management, Mental Health Teams
ECT
Mood Stabilizers Lithium, Valproic Acid, Carbamazepine
Drugs of choice for bipolar disorder, schizoaffective disorder and cyclothymia
Acute mania and prophylaxis of mania and depression in bipolar disorders
Less effective for bipolar disorder depression
Sometimes used for impulse control disorders, aggressive behaviour and mood management in personality d/o
LithiumUsed in Bipolar mania, but also popular as an
antidepressant augmenter (especially resistant)
Forms: regular, slow release, liquid
300-1200mg total daily dose (OD or BID dosing) Start with 300mg OD/BID
Dose increased over 7 to 10 days until plasma level 0.8 to 1.2 mEq/L (0.8 to 1.2 mMol/L) for acute mania
Lower in elderly (0.4 –1.0) 0.6 to 0.8 mEq/L for maintenance Usual dose range: 900 mg/day to 2100 mg/day Make sure to measure levels 12 hrs after the preceding
dose
LithiumBaseline Labs: BUN, Creat, lytes, FBG, TSH, fT4,
ECG>40yrs or cardiac disease
Effects: 2 weeks, need 4-8 weeks for trial (7-14 days for acute mania)
Levels: drawn on day 5, usually weekly for first 1-2 month, then q2-4wks.
Watch TSH and Creat q6months
For side effects relief always think sustained release or spreading the dose aroundFor tremor consider beta blocker
Predictors of Lithium Response
Previous or family history of response
Few previous manic episodes
“Classic mania” (not mixed)
Lack of rapid cyclingLess effective than Valproic Acid in rapid cycling
Lithium: SEsAcute SE
GI (nausea, diarrhea)
Neuro (drowsiness, cognitive dulling, fine hand tremor)
Metabolic (wt gain)
Derm (rash, worsening of psoriasis, acne)
GU (polydipsia/polyuria, DI)
Hematologic (mild leukocytosis common)
Long-term SE
Hypothyroidism (20%)
GU: impaired concentration of urine, DI, renal parenchymal changes, rare kidney failure
Lithium: Toxicity/OverdoseSymptoms:
Mental status changesNausea/VomitingIncontinenceCourse hand tremorDysarthriaGait ataxiaCardiac: depressed ST segments, T wave inversions, arrhythmias
CAN BE FATAL
Causes:
Dehydration, NSAIDs, ACEi, diuretics can increase Li levels
Management: Stop lithium Supportive medical care Draw lithium levels Dialysis if serum level >
4 or if clinically indicated
Valproic AcidEffective for bipolar disorder, schizoaffective
disorder, cyclothymia
More effective than lithium for rapid cycling and mixed state episode bipolar disorder
Can also be used for impulse control disorders, aggression and Cluster B personality disorders
May take up to 14 days to see antimanic effect
Trial of 4 to 6 weeks should be completed
Valproic Acid - Dosing Starting dose: 20 mcg/kg for rapid stabilization
of maniaApprox: 500 mg TID or 750 mg BID
Titrate up to serum level of 50 to 125mg/mL (350 – 700) = Avg maintenance dose: 1500 to 3000mg/day Available in once daily or divided doses
Elderly require approximately half that of younger adults
Valproic AcidLabs
Baseline: CBC, LFTs
Serum levels, CBC, platelet count, and PT/PTT should be done weekly during first month
Serum levels, CBC, LFTs Q3-6months
SEs
Favourable SE profile and lower toxicity compared to Lithium
Nausea, diarrhea, headache, sedation, fine tremor, weight gain, alopecia, leukopenia, neutropenia, thrombocytopenia, elevated LFT’s – in rare cases liver failure and/or pancreatitis
Lamotrigine Anticonvulsant
Indicated for bipolar depression
More effective in the treatment of bipolar depression compared to other mood stabilizers
Also used in treatment resistant unipolar depression
Used as monotherapy or adjuncive tx to other mood stabilizers and/or antidepressants
Lamotrigine – DosingInitial dose: 25 mg OD, increased weekly by 25
mg/week until you reach 200 mg/day
Up to 400 mg may be required to treat depression
Once or twice daily dosing usually qhs
Therapeutic effect may be seen in 2 to 4 weeks
LamotrigineLabs
Baseline: renal and hepatic fx (both involved in excretion)
Serum levels not useful as therapeutic window not yet determined
SEs
Very well tolerated by most patients
HA, somnolence, nausea, diarrhea, dizziness, ataxia, diplopia, blurred vision
RASH (10%): limbs
Steven – Johnson (0.3%): chest, neck, face, oral mucosa
If rash of any sort advise pt to DC and see MD immediately
CarbamazepineAnticonvulsant
Used in pts who do not respond to lithium
Starting dose: 200 mg BID
Maintenance dose: 800 to 1600 mg/dayDivided BID or TID to minimize SE
Serum level 25 to 60 mM
Carbamazepine – SEsAgranulocytosis and aplastic anemia (1 in 20
000)
Induction of liver enzymes: effects most psych meds, decreased effectiveness of OCP, auto–induction (half life and serum level decrease with time)
SJS reported (rare)
Second Generation Antipsychotics:
Evidence for efficacy as monotherapy and add-on mood stabilizers for:Risperidone, Olanzapine, Quetiapine
Same doses as treating psychotic d/oRisperidone 4-8mg/dOlanzapine 15-35mg/dQuetiapine 600-900mg/d

SummaryDepression:
Bereavement exclusion gone, but use clin judgement
MAOi/TCAs rarely usedAnti-depressants equally efficacious S/E profileWatch for serotonin syndrome
Bipolar disorder:New criteria: mood PLUS energy/ goal-directed
activityWatch for lithium toxicity
Thank-you! QUESTIONS?
:):
Hypertensive Crisis: “the cheese reaction”
Tyramine causes a potent release of NE
In the absence of an MAO-I, tyramine is broken down by MAO-A in the gut, liver and any NE released is broken down in the synaptic cleft
Normally a person can ingest 400mg of tyramine with no increase in BP (a high tyramine meal only has 40mg)
Drug-drug interactions can also lead to hypertensive crises (decongestants, stimulants, SNRIs)
TCA OverdoseMost symptoms related to anticholinergic load:
delirium, tachycardia, dilated pupils, ileus
Seizures and coma (mechanism poorly understood)
Cardiotoxicity mediated via the Na channel blockadeArrhythmias ECG changes: QT prolongation, widening of the
QRS, AV blockade, V tach
Severe hypotension (a-adrenergic blockade)
TCA Overdose Management
Hospitalization, cardiac monitoring (continue for 24 hours after signs of toxicity have resolved)
Charcoal
IV fluid resuscitation
Bicarb infusion to treat acidosis
Psychiatric consult
