Abstract
Lacosamide (LCM) due to no known drug interaction and the absence of metabolic enzyme
induction is a good candidate for an add-on medication, especially in combination
with lamotrigine, levetiracetam (LEV), oxcarbazepine, topiramate, and valproic acid
(VPA). Here we report for the first time, to our knowledge, that LCM can lower VPA
and LEV serum levels. At present, there are no known explicable mechanisms of action
of LCM, which lowers VPA and LEV. Here observed drug interaction of LCM is of clinical
significance, which might be useful for other colleagues in the field.
