A 33-year-old man visits his psychiatrist with feelings of sadness on most days of the week for the past 4 weeks. He says that he is unable to participate in his daily activities and finds it hard to get out of bed on most days. If he has nothing scheduled for the day, he sometimes sleeps for 10–12 hours at a stretch. He has also noticed that on certain days, his legs feel heavy and he finds it difficult to walk, as though there are bricks tied to his feet. However, he is still able to attend social events and also enjoys playing with his children when he comes home from work. Other than these simple pleasures, he has lost interest in most of the activities he previously enjoyed. Another troubling fact is that he had gained weight over the past month, mainly because he eats so much when overcome by these feelings of depression. His is prescribed a medication to treat his symptoms. Which of the following is the mechanism of action of the drug he was most likely prescribed?
