Methylphenidate Fluoxetine

There are four classes of antidepressants tricyclic antidepressants (imipramine, trimipramine, amitriptyline, doxepin, desipramine, protriptyline, nortriptyline, amoxapine, maprotiline) monoaminooxidase (MAO) inhibitors (phenelzine, isocarboxazid, tranylcypromine) second-generation antidepressants or atypical antidepressants, which are a chemically dissimilar group of recently proposed drugs (bupropion, trazodone, fluoxetine) and amphetamines and other stimulators of the CNS (dextroamphetamine, methylphenidate). 

The safety and efficacy of combined SSRI and stimulant pharmacotherapy have been addressed in two open studies. Gammon and Brown (1993) reported on the successful addition of fluoxetine to stimulants in the treatment of 32 patients with ADHD with comorbid depressive and anxiety disorders (Gammon and Brown 1993). These children with comorbid conditions had failed to respond to methylphenidate alone. Another report detailed the addition of methylphenidate to SSRI treatment (Findling, 1996). Depressed children and adults with comorbid ADHD were treated with either fluoxetine or sertraline. While depressive symptoms remitted, ADHD symptoms persisted. Methylphenidate was added and successfully treated the ADHD symptoms. In both investigations, the combined treatment was well tolerated.

Loof et al. (1995) reported the use of carbamazepine (300-1200 mg/day, serum levels 10-11.5 pg/mL) in 28 children and adolescents with sexual abuse histories. By treatment end, 22 of 28 patients were asymptomatic of PTSD. The remaining six were significantly improved in all PTSD symptoms except for continued abuse-related nightmares. Half of this cohort had com-orbid ADHD, depression, ODD or polysubstance abuse and were treated with concomitant medications, e.g., methylphenidate, clonidine, sertraline, fluoxetine, or imipramine. 

Fluoxetine, paroxetine, bupropion, duloxetine, and other CYP450 2D6 inhibitors may increase TCA concentrations Cimetidine may increase plasma concentrations of TCAs and cause anticholinergic symptoms Phenothiazines or haloperidol may raise TCA blood concentrations May alter effects of antihypertensive drugs may inhibit hypotensive effects of clonidine Use of TCAs with sympathomimetic agents may increase sympathetic activity Methylphenidate may inhibit metabolism of TCAs... 

Of the various drugs which have been tried in BN, fluoxetine has the largest body of evidence in its favour. It is therefore the preferred treatment, perhaps combined with CBT. If this proves ineffective or is poorly tolerated, topiramate, methylphenidate or naltrexone might be tried.
