A 72-year-old man with a 4-year history of Parkinson disease comes to the physician for evaluation of his medication. Since his last visit one year ago, he has had increased tremor and bradykinesia up to an hour before his next scheduled dose and sometimes feels like he does not respond to some doses at all. One week ago, he was entirely unable to move for about a minute when he wanted to exit an elevator. The physician prescribes a drug that increases the bioavailability of levodopa by preferentially preventing its peripheral methylation. This patient was most likely prescribed which of the following drugs by the physician?
