Venlafaxine versus fluoxetine in the treatment of atypical anorectic outpatients: a preliminary study.

The efficacy of venlafaxine and fluoxetine in the treatment of atypical anorexia nervosa (AN) was compared in a controlled trial. A consecutive series of 24 atypical anorectic females was assigned to either venlafaxine (75 mg/day) or fluoxetine (40 mg/day) plus cognitive-behavioural therapy (CBT). Eating Disorder Examination (EDE12.0D), Beck Depression Inventory (BDI) and State and Trait Anxiety Inventory (STAI) scores were compared before and after 6 months of treatment. Venlafaxine and fluoxetine determined an increase of body mass index (BMI) and a significant reduction of EDE12.0D and BDI scores; venlafaxine alone reduced STAI scores. It would seem that venlafaxine is as effective as fluoxetine when combined with CBT in the treatment of atypical AN.
