• Li and an antipsychotic
• Valproate and an antipsychotic
Meds

ill, list medication options. List FDA
approved.
Meds
• Ans. Practice guidelines uses a lot of “may” as to
mild or moderate manic episodes:
• -- Li

[FDA’s list: aripiprazole, chlorpromazine, Li,
olanzapine, quetiapine, risperidone, valproate,

Li and antipsychotic
Q. You’ve placed your pt with mania on Li
and she is no better, after two week. You
add ziprasidone and still not better five
days later. What to do?
Li and antipsychotic

G & J, p 729
Benzodiazepines
• Q. Role of benzodiazepines in manic or
mixed episodes?
Benzodiazepines
• Ans. As an adjunct and for only a short
time. G & J use for insomnia to get the pt’s
sleep pattern normal.
Antidepressants
• Q. What should be the approach to a pt on
antidepressants and treating that pt’s firstbreak manic episode?
Antidepressants
• Ans. The antidepressant should be
tapered and discontinued if practical.
“breakthrough”
• Q. How to manage breakthrough manic or
mixed episode? By “breakthrough,” we
mean that the pt was on a maintenance
med or meds and now has a manic
episode.
breakthrough
• Ans.
• 1. Check serum levels to see if the pt is in
therapeutic levels and consider higher levels
that are still with acceptable levels, e.g.
valproate at 90, consider pushing to 120..
• 2. Consider adding an antipsychotic
• 3. Consider short-term use of a benzodiazepine,
especially if very agitated.
Inadequate Response
• Q. If first choice med fails to develop an
adequate in a manic or mixed pt in two
weeks, what to do? [Ans. has five general
categories.]
Inadequate response
• Ans. Consider:
– Another first line med
– Adding an antipsychotic if not already using.
If using, consider switching to another
antipsychotic.
– Adding carbamazepine/oxcarbazepine
– Clozapine [Practice Guideline wording not
clear, but apparently as an addition, not a
substitute]
– ECT
ECT
• Q. When is ECT an especially attractive
option in the manic or mixed pt?
ECT
• A. Attractive when:
• 1] Mania very severe and not responding
to meds.
• 2] Pt prefers ECT
• 3] Pregnant
• 4] Psychotic signs prominent.
• [not listed in practice guideline, but
catatonic or suicidal are probably correct
answers too]
Acute depression

depression in bipolar?
Acute depression
• Ans. Three: Li, lamotrigine or olanzapinefluoxetine combination.
[Ref: Watch]
SSRIs
• Q. What about SSRIs for depressive
episode?
SSRIs
• Ans. Not recommended as monotherapy.
May be useful as an adjunct to a mood
stabilizer, but mood stabilizers are first
choice.
• [I gather tertiary centers for bipolar
disorders find they have to use an
antidepressant with about a fifth of their
pts, but exam not likely to reach this.]
Acute depression
• Q. When to consider ECT for acute
depression in bipolar pt?
Acute depression
•
•
•
•
•
Ans. ECT is useful for:
1] life-threatening inanition
2] suicidal
3] psychotic
4] pregnant
Acute depression
• Q. What about psychotherapy?
Acute depression
• Ans.
• In addition to meds – not as solo,
interpersonal or CBT has empirical basis.
• Psychodynamic is frequently used but
lacks controlled studies.
Breakthrough depression
• Q. Bipolar pt on maintenance meds and
has breakthrough depression. What to
do?
Breakthrough depression
• Ans. First, ensure serum levels of meds
are at high therapeutic range.
Breakthrough depression
• Q. If serum levels of the mood stabilizers
are at a high therapeutic level and still
depressed? [“Breakthrough depression” =
bipolar pt who was on maintenance mood
stabilizer as adequate levels. List three
general choices.]
breakthrough depression
• Ans. Three general choices.
• 1] Add antidepressant:
SSRI/venlafaxine/bupropion or MAOI or
• 2] If psychotic, add antipsychotic [probably
an acceptable choice even if not
psychotic], or
• 3] ECT
Still depressed
• Q. When to consider ECT?
Still depressed, ECT
•
•
•
•
Ans. ECT when:
-- medication resistant
-- psychotic signs
-- catatonic features
Rapid cycling
• Q. What is definition of rapid cycling?
Rapid cycling
• Ans. 4 or more episodes/year and there
has been two months of remission or
partial between episodes. Hypomanic
episodes count. Rapid cycling also can
mean switching from one polarity to the
opposite without the two months of
remission or partial remission.
Rapid cycling
• Q. Identify two conditions that can lead to
rapid cycling.
Rapid cycling
• Ans. There are lots, and the Practice
Guideline lists two that may be among the
exam’s choices
• -- substances, including alcohol
• -- hypothyroidism [yes, hypo, not hyper]
Rapid cycling
• Q. Meds for rapid cycling?
Rapid cycling - meds
Meds for rapid cycling:
• Li
• Valproate or
• Lamotrigine
Rapid cycling
• Q. Rapid cycling pt doesn’t respond to
your initial med selection, so what next?
Rapid cycling
•
•
•
•
•
Ans. Two choices?
-- Add another mood stabilizer
Or
-- Add an antipsychotic
[While not mentioned by Guideline, ECT is
also an acceptable answer]
Catatonic signs
• Q. Which phase has catatonic signs and of
what signs do they commonly consist?
Catatonic signs
• Ans. More common in manic episodes and
consist of motor excitement, mutism, and
stereotypic movements.
Catatonic
• Q. Treatment choice for bipolar with
catatonia?
Catatonia
• Ans. While ECT is most efficacious,
Practice Guideline seems to imply trying a
benzodiazepine first.
Maintenance
• Q. Preferred meds for the maintenance
[stable] phase of pt with bipolar disorder?
Maintenance
• Ans.
• Treatments with the most empirical
support are Li and valproate.
• Possible alternatives are lamotrigine,
olanzapine, carbamazepine of
oxcarbazepine.
Watch provides additional support for
lamotrigine and olanzapine.
Maintenance - ECT
• Q. ECT?
Maintenance - ECT
• Ans. Maintenance ECT should be consider
for those pts whose stabilization was
achieved with ECT.
Maintenance - Antipsychotics
• Q. Role of antipsychotics for
maintenance?
Maintenance - antipsychotics
• Ans. Not easy to answer. Practice Guidelines
says they should be discontinued unless they
have been shown with a pt to be needed to
prevent relapse or to prevent psychotic features.
• APA Watch on bipolar suggests that olanzapine
is OK for maintenance, and is clear in saying
that typical antipsychotics are not desirable.
Other atypicals are listed for maintenance [e.g.,
Stephen Stahl’s Prescription Guide].
Maintenance - psychotherapies
• Q. Role of psychotherapies. If a role,
which are used?
Maintenance - psychotherapies
• A. CBT has been shown to reduce number
of exacerbations. Supportive and
psychodynamic therapies are commonly
used in addition to the meds.

• Q. During maintenance, is group therapies
used and, if so, for what purpose?
Maintenance – group therapy
• Ans. Supportive groups are used to
educate as to:

– Adaptation to having a chronic illness
– Management of psychosocial issues, e.g. job
related issues
Maintenance – family therapy
• Q. Family therapy in the maintenance
phase is used to?
Maintenance – family therapy
• A. Same as the issues listed for group
psychotherapy supra.
Maintenance - problems
• A. During maintenance, if the pt is still
having subthreshold symptoms or
breakthrough manic or depression, what to
do?
Maintenance - problems
•
•
•
•
A. Consider:
-- adding another mood stabilizer
-- adding an atypical antipsychotic
-- adding an antidepressant if the mood
breakthrough is depressive signs.
• -- adding maintenance ECT

Valproate - dosing
• Ans.
• For hospitalized inpts in manic phase, 2030 mg/kilo, aiming for blood level of 50 125.
• B. For outpts, 250 mg tid and go up slowly
aiming for blood level of 50 – 125.
Valproate - ER
• Q. How does Extended Release valproate
compare to immediate release in terms of
blood level of the med?

tests are still indicated and how often?
Valproate – lab tests

functions every 6 months.
Valproate & lamotrigine
• Q. Pt on valproate and you want to add
lamotrigine. What dose of lamotrigine is
advised?

children? In adults?
Lamotrigine – Stevens-Johnson
• Q. 1% in children. 0.3% in adults in the

• Q. What is typical lamotrigine dosing?
Lamotrigine dosing
• A. 25 mg/d for 2 weeks, then increase 25
mg every two weeks until desired clinical
results or reach 200 mg/d. [If pt is also on
valproate, would be ½ that.]
Lamotrigine & carbamazepine
• Q. Lamotrigine doses when combined with
carbamazepine?
Lamotrigine & carbamazepine
• A. Carbamazepine increases metabolism
of lamotrigine, so will need to use

• Ans. Increases the metabolism and
reduces their effectiveness.
Pregnancy - Li
• Q. Your pt on Li becomes pregnant. Your
advice should include?
Pregnancy - Li
• Ans. While wording, obviously varies from
pt to pt, the facts are that Ebstein’s
anomaly is 10-20 times more common if
on Li during first trimester. Discontinuing
Li, especially rapidly, however, increases
chance of return of bipolar episodes.

• Ans. None, including tricyclics, have been
shown to be teratogenic.
