Star*D trial overview
pragmatic (real world) trail which aimed to assess the effectiveness of treatments in patients diagnosed with major depressive disorder. It consisted of four different levels of treatment Level 1 - This consisted of citalopram (given for 14 weeks) Level 2 - This consisted of either swapping to sertraline, Bupropion, or venlafaxine, or augmenting with Bupropion, or buspirone. Cognitive psychotherapy was also included as a switch or add on at this level. Level 3 - This consisted of swapping to mirtazapine or nortriptyline or adding on lithium or triiodothyronine (T3). Level 4 - This consisted of swapping to either tranylcypromine (MAOI) or a combination of venlafaxine and mirtazapine. Outcome measure used was remission (becoming symptom free).
64
Main conclusions of star*d trial
In level 1 1/3 of participants achieved remission. A further 10-15% responded but not to the point of remission. If treatment with an initial SSRI fails then 1 in 4 who choose to switch to another medication will enter remission regardless of whether the second medication is an SSRI or a medication of a different class. If patients choose instead to add a medication on 1 in 3 will get better
65
Most common cause of serotonin syndrome
The most frequent cause of severe reaction is the co-administration of an MAOI with an SSRI.

Which combinations of antidepressants should be avoided?
Phenelzine and sertraline (MAOI + SSRI) | The combination leads to a high risk of serotonin syndrome.
