Ch 33 Bipolar Meds Flashcards
BPD is treated with three kinds of drugs:
mood stabilizers,
antipsychotic drugs, and
antidepressants
Mood stabilizers are drugs that (3)
(1) relieve symptoms during manic and depressive episodes;
(2) prevent recurrence of manic and depressive episodes; and
(3) do not worsen symptoms of mania or depression and do not accelerate the rate of cycling.
Antipsychotic drugs are used acutely to __, and long term to __. Benefits occur in patients with and without psychotic symptoms.
treat manic episodes
help stabilize mood
In patients with bipolar depression, using an antidepressant alone may induce __.
mania—although the risk appears lower than previously believed.
Nonetheless, to minimize risk of mania, antidepressants should not be routinely used alone; rather, they should be combined with a mood stabilizing drug.
(2) are the preferred mood stabilizers for BPD.
Lithium and valproate
To minimize the risk of toxicity, lithium levels must be
monitored. The trough level, measured ___, should be less than 1.5 mEq/L.
12 hours after the evening dose
Common side effects that occur at therapeutic lithium levels include (3).
tremor, goiter, and polyuria
Lithium may be ___.
teratogenic, and hence should be avoided during the first trimester of pregnancy.
Also, unless the benefits outweigh the risks, lithium should be avoided during the second and third trimesters too.
A reduction in __ will reduce lithium excretion,
causing lithium to accumulate—possibly to toxic levels.
sodium levels
Patients must maintain normal sodium intake and levels.
Lithium levels can be increased by (2).
diuretics (especially thiazides) and by several nonsteroidal anti-inflammatory drugs
