Exam Questions and Answers:
1. Most psychotropic medications operate in this fashion:---
Correct Answer---"when you double the dose, the serum dose
doubles."
*minus three SRIs and three anticonvulsants (Fluoxetine,
fluvoxamine, paxil, gabapentin, valproate and carbamazepine)
,2. induces it's own metabolism, hastening excretion
and shortening it's half life---Correct Answer---A.
Carbamazepine (Tegretol)
*this ettect begins to "rev up" after 2-4 weeks--which is why a
carbamazepine level is so important on obtaining 1-2 months
after starting Tegretol.
3. Carbamazepine (Tegretol) level should be checked how
soon after starting to take this med---Correct Answer---1-2
months due to Tegretol inducing it's own metabolism,
hastening excretion and shortening it's half life.
4. has trouble getting a "serum" level because it binds
to proteins that render it therapeutically inactive---Correct
Answer---A. Valproate Acid (Depakote)
-this is particularly true at the lower levels (eg. <50 mcg/mL),
so you can expect dose changes to make a more dramatic
ditterence when the pt's depakote level is in the higher range
5. 's serum level is the opposite of Valproic Acid: it
rises quickly at first and then slows down---Correct Answer---
Gabapentin
*gabapentin saturates the transporters that absorb it in the
small intestine, causing its levels to rise at a snails pace when
the dosage goes above a certain saturation point (around 900
mg/day).
, -from there, the saturation trickles down; @ 900 mg/day--
60% is absorbed. @ 1200 mg/day--50 % is absorbed. @3000
mg/day--30% of the gabapentin is absorbed.
6. Due to Gabapentin's serum pattern for dosage:
@ 900 mg/day, how much is the patient absorbing---Correct
Answer---@ 0900mg/day---60% is absorbed.
7. Due to Gabapentin's serum pattern for dosage:
@ 1200 mg/day, how much is the patient absorbing---Correct
Answer---@ 1200 mg/day--50 % is absorbed.
8. Due to Gabapentin's serum pattern for dosage:
@ 3000 mg/day, how much is the patient absorbing---Correct
Answer---@3000 mg/day--30% of the gabapentin is absorbed.
9. Carbamazepine (Tegretol's) serum level drops after how
long after stopping taking it---Correct Answer---1-2 months
10. For Valproate (Depakote), dose changes can have big
effects once the level is beyond 50 mcg/mL---Correct Answer--
-SMALL
11. potency refers to a drug's>---Correct Answer---power per
unit
-or the amount of pharmacological activity per milligram.
12. Delayed release=: modified release
