Extrapyramidal symptoms associated with the adjunct of nortriptyline to a venlafaxine-valproic acid combination.
The onset of extrapyramidal symptoms has been traditionally linked to the prescription of neuroleptic treatment: there are some reports in the international literature describing extrapyramidal effects related to antidepressant. In this paper we present a case under multiple pharmacologic treatment in whom extrapyramidal symptoms developed shortly after the adjunct of nortriptyline to a combination of venlafaxine and valproic acid administered for several months. We describe here the clinical history of this patient, affected by Bipolar Disorder, type II, and the progressive pharmacologic path in his treatment. Possible hypothesis to explain this evidence are discussed.
