what have the differences in response rate generally been between ADs in head to head trials
modest–> 5-6%
list the 4 ADs that have level 1 evidence for superior efficacy per the CANMAT guidelines
escitalopram
mirtazapine
sertraline
venlafaxine
list the 2 ADs that have level 2 evidence for superior efficacy based on the CANMAT guidelines
agomelatine
citalopram
is there any AD that can be cited as demonstrating superior functional improvement?
no
which AD seems to have lower rates of sexual side effects
buproprion
(also vortioxetine, agomelatine, desvenlafaxine, mirtazapine, vilazodone)
which ADs seem to have higher rates of sexual side effects
escitalopram
paroxetine
are there clear differences in tolerability of ADs?
no–> based on product monographs
(*Dr. Rhandawa’s lecture I recall indicating that vortioxetine may be better tolerated)
what is the relationship between ADs and suicide risk
for SSRIs in adolescents–> DOUBLE the risk of suicide w SSRI use but this was based on OBSERVATIONAL studies (use caution; black box warning… no specific ADs, caution in all)
in adults (above age 25) and the elderly (above age 65), ADs seem to show decreased suicidal ideation + acts/attempts
in adults, risk may be DECREASED by as much as 40% and in elderly may be by as much as 50% with use of SSRIs
which 3 ADs have been most implicated with QTC prolongation
citalopram
escitalopram
quetiapine
what is the association between ADs and QTc prolongation/torsades
torsades is often idiosyncratic, unclear associations
per systemic review, can occur even at therapeutic dose and torsades can occur even with normal QTc
most cases had additional risk factors –> without additional risk factors, VERY LOW RISK with SSRIs/ADs
with which AD should you monitor LFTs
agomelatine–> can icnrease liver enzymes and there is sporadic toxic hepatitis
(uncommon with other ADs)
list 4 other possible adverse consequences of SSRI use
- increased falls
- increased fractures–> highest risk within first 6 weeks of exposure to SSRI
- hyponatremia
- inhibited platelet aggregation–> increased risk of GI bleeding
what population is particularly as risk of SSRI associated hyponatremia
elderly patients with other risk factors
what can increase the risk of GI bleed in patients taking SSRIs
NSAIDs–> concomittant NSAID use increases risk of GI bleed by 2x
what is one way to significantly reduce the risk of GI bleed in patients taking SSRIs
acid suppressing drugs
