A 12-year-old boy presents to the pediatrician with complaints of chronic cough for the past two years. The cough is present during the day, especially after returning from school. His school teacher says he does not cough at school. The cough is absent while he is asleep, although it increases during examinations or when he experiences boredom. His mother reports that there was a one-month period where he did not cough, but during that month, he used to shrug his shoulders frequently, especially when he was stressed or fatigued. There is no history of sneezing, nasal discharge, nasal congestion, headache, ear symptoms, or breathing difficulty. Detailed history does not suggest the presence of a mood disorder, obsessive-compulsive symptoms, or attention-deficit/hyperactivity disorder. There is no past history of a known neurological disorder, and there is no history of substance abuse. On physical examination, his vital signs are stable. Examination of his respiratory and cardiovascular systems is normal. However, the pediatrician notes repeated eye blinking; upon asking about eye blinking, the mother reports that he has had this habit since he was almost eight years old. Further inquiry suggests that eye blinking, coughing, and grunting disappear for a few weeks without explanation, only to reappear again. Which of the following drugs is likely to be most effective to control this patient’s symptoms?
