A 28-year-old medical student presents to the student health center with the complaint being unable to sleep. Although he is a very successful student, over the past few months he has become increasingly preoccupied with failing. The patient states that he wakes up 10-15 times per night to check his textbooks for factual recall. He has tried unsuccessfully to suppress these thoughts and actions, and he has become extremely anxious and sleep-deprived. He has no past medical history and family history is significant for a parent with Tourette's syndrome. He is started on cognitive behavioral therapy. He is also started on a first-line medication for his disorder, but after eight weeks of use, it is still ineffective. What drug, if added to his current regimen, may help improve his symptoms?
