“…The drugs most used in EF are antiseizure medications; satisfactory therapeutic responses have been reported for several drugs in this group, especially gabapentin (30,(71)(72)(73)(74)109,116,(120)(121)(122)124) and lamotrigine (71)(72)(73)(74)(75)116,120,121,124) but also pregabalin (74,121), carbamazepine (73,103,117,121), oxcarbazepine (120,121), eslicarbazepine (107,121,125), lacosamide (121), and levetiracetam (74). Amitriptyline (73,75,116,122), duloxetine (120), and indomethacin (74,75) have also been used with effect in a minority of patients. If the response to initial treatment is unsatisfactory, another treatment may be tried, as patients who do not respond to the first option may find relief with subsequent options.…”
