  • reduced concentration

27
Q

What is the monoamine theory of depression ?

A

Depression is associated with decrease in brain NAd (noradrenaline) and/or 5HT (serotonin).

antidepressants rapidly inhibit uptake or breakdown of monoamines but clinical improvement takes up to 4-6 weeks.

28
Q

What are the classes of antidepressants?

A

1) Mono-amine reuptake inhibitors
- tricyclics
- SSRIs (1st line)
- NARI
- SNRI
- NaSSa

2) Receptor Antagonists
3) Monoamine oxidase inhibitors

29
Q

Give 2 examples of tricyclic antidepressants. What are the main side effects? and dosage?

A

Tricyclics are Nad and 5HT reuptake inhibitors. They have a long half life so are usually taken once a day.

more sedative:

  • clomipramine,
  • doxepin,
  • mianserin,
  • trazodone
  • trimipramine
  • dosulepin (dangerous in overdose so not recommended)
  • amitriptyline (dangerous in overdose so not recommended)

Less sedative:

  • Lofepramine (less side effects)
  • imipramine,
  • nortriptyline.

Side effects:

  • toxicity in overdose
  • Anticholinergic (dry mouth, blurred vision, photophobia, tachycardia, difficulty in urination, hyperthermia, glaucoma, and mental confusion (elderly).
  • Arrhythmias (QT prolongation)
  • Sedation
30
Q

SSRIs are first line in the treatment of depression. Give examples of some SSRIs, the side effects and risks.

A 
SSRI examples:
citalopram 
fluoxetine 
sertraline 
paroxetine

Side effects:

    • hyponatraemia
    • Serotonin syndrome
    • Increased suicidal thoughts + behaviour (caution in young people)
  • GI upset
  • lower seizure threshold (therefore caution with epilepsy)
  • increases risk of bleeding (caution with peptic uclers)
  • skin rash
  • appetite / weight loss or gain
31
Q

What is the association between hyponatraemia and antidepressants?

A

1) Hyponatraemia should be considered in all patients who develop drowsiness, confusion, or convulsions while taking an antidepressant.
2) can occur with any antidepressant but reported more frequently when on SSRIs.

32
Q

How often should patients be reviewed once starting an antidepressant and how long should they remain on it?

A

1) patients should be reviewed every 1-2 weeks at the start of the treatment.
2) treatment should be tried for at least 4 weeks before switching to another antidepressant.
3) once in remission the drug should be continued at the same dose for at least 6 months.

33
Q

How often should patients be reviewed once starting an antidepressant and how long should they remain on it?

A

1) patients should be reviewed every 1-2 weeks at the start of the treatment.
2) treatment should be tried for at least 4 weeks before switching to another antidepressant.
3) once in remission the drug should be continued at the same dose for at least 6 months.
4) the drug should be reduced over 4 weeks to stop it.

34
Q

What is serotonin syndrome?

A

Serotonin syndrome is a relatively uncommon reaction to excess serotonin activity.
It is characterised by:
1) neuromuscular hyperactivity (e.g tremor, hyperreflexia, clonus, myoclonus, rigidity),
2) autonomic dysfunction (tachycardia, blood pressure changes, hyperthermia, diaphoresis, shivering, diarrhoea)
3) altered mental state (agitation, confusion, mania)

Treatment involves withdrawal of serotonergic medication (get specialist advice)

35
Q

What would you do if a depressed patient fails to respond to the initial 1st line treatment : SSRI ?

A

1) try a higher dose of the same drug / switch to another SSRI
2) try mirtazipine (NaSSA) or other drug classes e.g. lofepramine (Tricyclic), moclobemide(MOAI), and reboxetine (NARI)
3) other tricyclics and venlaflaxine (SNRI) should be considered for more severe depression.
4) specialists may try augmenting an antidepressant with a mood stabiliser such as lithium
5) ECT for very severe depression.

36
Q

Which SSRI is known to prolong the QT interval and can predispose to arrhythmias?

A

Citalopram

37
Q

where are SSRIs metabolised?

A

liver

38
Q

What are the important drug interactions for SSRIs

A

Be cautious when prescribing SSRIs with:

1) monoamine oxidase inhibitors (both increase serotonin –> serotonin syndrome)
2) NSAIDS or Aspirin —> give PPI to avoid gastric bleeding.
3) anticoagulants (due to increased bleeding risk)
4) antipsychotics (both prolong QT interval)

39
Q

What is the typical starting dose for SSRIs

A

20mg orally daily, at the same time everyday.

dose is increased as necessary

40
Q

Why should SSRIs not be stopped suddenly?

A 
They are not addictive but you can get discontinuation symptoms :
flu like symptoms, 
sleeplessness, 
GI upset,
mood swings
41
Q

Give 2 examples of SNRIs (Serotonin and Norepinephrine reuptake inhibitors)

A
  • venlaflaxine

- duolexetine

42
Q

What antidepressant may be given to a patient experiencing insomnia and loss of appetite?

A

Mirtazipine - because the side effects include sedation and increased appetite/

43
Q

What antidepressant causes painful and persistent penile erection (priapism)?

A

Trazadone (TCA)

44
Q

name 2 drugs which have particularly bad discontinuation symptome?

A

1) Venlafaxine (SNRI)
