One week after starting a new medication, a 16-year-old girl is brought to the emergency department by her mother because of a painful, blistering rash. She has a history of bipolar disorder. Her temperature is 39°C (102°F). Physical examination shows numerous coalescing bullae with epidermal detachment covering the face, trunk, and extremities. There are hemorrhagic erosions on the hard palate and buccal mucosa. When lateral pressure is applied to healthy-appearing skin at the edge of a bulla, a blister starts to form. Which of the following drugs is most likely responsible for this patient's current condition?
