5-HT2A receptorsStudies using sleep EEGs on new drugs like nefazodone and mirtazapine suggest that 5-HT2A blockade produces an improvement in sleep patterns that is clinically useful. Many antidepressant drugs have such properties, data as below. Low numbers means high potency, ie bigger effect.
Many neuroleptic drugs, both old and new, are also potent 5-HT2A blockers.SSRIs nil sig except
fluoxetine 280Trimipramine 15
Amitriptyline 18
Clomipramine 23
Doxepin 27
Trazodone 25
Nefazodone 26
mirtazapine ~30
Nortriptyline 41Imipramine 150
desipramine 350
lofepramine 200

My understanding is that anafranil has the most effect on 5-HT when compared to other tricyclics too, but it also affects a lot of other receptors, ie: clomipramine, imipramine, amitriptyline & doxepin all have very similar NE reuptake inhibiting abilites.
