PG Flashcards
ABCB1 is a
p-gp
how C-T 3435 (SNP) change the activity
change the rate of translocation
mis-folding of the protein
change the activity
how does that influence the dose
increase the conc in the brain
reduce the dose
guideline for the dose ?
not enough evidence
phenytoin is mostly metabolised by
CYP2C9
drugs which will be influenced by HLA-B 1502 mutation
phenytoin
carbamazepine
lamotrigine
phenobarbital
substances which will increase the activity for CYP2C9
SJW
alcohol will increase the serum conc for phenytoin Y/N
Y
Calcium containing antacids will increase the phenytoin plasma conc Y/N
N (decrease)
paroxetine is metabolised by
CYP2D6
paroxetine shows non-linear PK due to
the metabolites inhibit the CYP2D6
recommendation for CYP2D6 ultrarapid metaboliser
alternatives
for poor metaboliser
alternatives
sertraline only go through phase I metabolism Y/N
N
CYP2C9 plays a role in sertraline metabolism Y / N
N (CYP2C19)
