Inner tension Inability to feel

Reduced sleep Pessimistic thoughts

Reduced appetite Suicidal thoughts

Psychotherapy (especially indicated for mild,

recent-onset depression)

Monitoring

guided self help

cognitive behavioural therapy

Antidepressants (recommended for moderate

to severe depression, dysthymia)

Special consideration for children and elderly

patients

Selective serotonin reuptake inhibitors (SSRI)

Serotonin–norepinephrine reuptake inhibitor (SNRI)

Noradrenergic and specific serotonergic antidepressant (NaSSA) (e.g. mirtazapine)

Tricyclic antidepressants (TCAs)

Monoamine oxidase inhibitors (MAOIs)

Melatonergic agonist (agomelatine)

Benzodiazepines

Hypnotics

Bupropion

Act on serotonin reuptake

Citalopram

Fluoxetine

Escitalopram

Paroxetine

Sertraline

Fluvoxamine

Generally well tolerated

Clinical response 2-4 weeks (may be less in some pts)

Beware of drug interaction – some SSRIs are potent inhibitors of cytochrome P450◦ Eg. Fluoxetine (CYP 2D6, CYP 3A4) – increases

levels of antipsychotics, carbamazepine, ciclosporin etc

SE of agitation especially upon initial administration – poorly tolerated in pts with insomnia, significant anxiety, agitation, suicidal ideation

Act on both serotonin and nonepinephrine, though more selective for serotonin reuptake inhibition

Venlafaxine – first SNRI

Desvenlafaxine – active metabolite of venlafaxine

Duloxetine – neuropathic pain

Efficacious in non-responders to SSRI (STAR*D)

Bupropion

Originally developed as an antidepressant for

smoking cessation therapy

NE and dopamine reuptake inhibition

Can be used as monotherapy

Or adjunct in major depression disorder

Less sexual dysfucntion, wt gain

May have agitation, insomnia, seizure

For severe depression: combination of CBT

and antidepressants recommended

For treatment resistant depression:

augmentation with Lithium, antipsychotic,

add second antidepressant

ECT (for severe and treatment resistant

depression)
