TCA metabolite
parent –> metabolite
Amitriptyline –> Nortriptyline
Imipramine –> Desipramine
TCA MOA and SE
Blocks reuptake of NE & 5HT.
Anticholinergic
H1 and alpha-adrenergic antagonism
ADR
- GE and sexual dysfunction
- Anticholinergic,
- Sedation,
- weight gain,
- Orthostatic hypotension
- Arrhythmias,
- Seizure,
- Fatal on overdoses
secondary amine (nortyiptyline, despiramine) have lower anticholinergic, sedation and cardiotoxic side effects.
SSRI MOA and SE
Blocks reuptake of 5HT selectively
HYPONATREMIA (SIADH)
GI & SEXUAL dysfunction.
Fluoxetine –> insomnia
Headache,
transient nervousness during initiation
Bleeding risk
EPSE
-Paroxetine = most anticholinergic, sedating, increase weight, T ½ short.(withdrawal)
Escitalopram/ Citalopram: QTc prolongation if high dose in elderly/starvation/female
-Vilazodone: low risk in sexual dysfunction
SNRI MOA and SE
Blocks reuptake of NE & 5HT
HYPONATREMIA (SIADH) GI & SEXUAL dysfunction. Headache, transient nervousness during initiation Bleeding risk EPSE
increase BP (Venlafaxine) Urinary hesitation (Duloxetine)
NaSSA MOA and SE
Mirtazapine
A2-adrenoceptor antagonist
INCREASE 5HT & NE
5HT2&3, H1 antagonism
- Somnolence, INCREASE appetite, weight gain
- REVERSE GI and SEXUAL SE of SNRI/SSRI
NDRI MOA and SE
Bupropion
Blocks reuptake of NE & DA
Seizure,
Insomnia,
Psychosis
DECREASE sexual SE of SSRI/SNRI
Trazodone MOA and SE
Blocks reuptake of 5-HT;
Antagonizes 5-HT2A, H1 and A1 adrenoceptor
HYPONATREMIA (SIADH)
GI & SEXUAL dysfunction.
Headache,
transient nervousness during initiation
Bleeding risk
EPSE
Sedation
orthostatic hypotension
RARE SE: priapism
Agomelatine MOA and SE and DDI
MT-1, MT-2 agonist
GI, increase LFTs Interactions:
DDI : Fluvoxamine, Ciprofloxacin
(Cyp1A2 inhibitor)
Adjunct used as hypnotics
BZD
z-hypnotics
antihistamine
melatonin receptor agonist
Adjunct used as mood stabilizer
Second gen antipsychotics (atypical antipsychotics)
BZD
indication
MOA
SE
Doses and half life
hypnotics
potentiates GABA
SE: sedation drowsiness confusion amnesia
Lorazepam
Half life: 12 (8-25hr)
adult dose: PO 0.5-2mg HS PRN (bedtime)
Diazepam
Half life: 20-54hr
adult dose: PO 2-15mg HS PRN (Bedtime)
Minimise risk for dependency by limiting to 2 weeks PRN short course therapy
Z-hypnotics
MOA
SE
Doses and half life
Preferentially binds to benzodiazepine binding sites with gamma and A1 subunits (causes sedation).
SE:
Taste disturbance (zopiclone)
complex sleep behaviour (sleep walking)
- perform hx on childhood sleep walk
Zolpidem: Halflife: 1.5-4hr Adult dose: >18yo PO 10mg HS PRN CR 6.25-12.5mg HS PRN women: Half dose
Elder/debilitated
PO 5mg HS PRN (increase if necessary)
Zolpiclone
Half life: 6hr
Adult dose:
>18yo PO 7.5mg HS PRN
