Answer:
Bob's doctor has probably been treating him with MAOIs term.
Explanation:
Monoamine oxidase inhibitors, MAOIs, are the first substances to be used as antidepressants in the 1950s. They are prescribed until today, but in the 1970s they were withdrawn from the market because they had a risk of severe high blood pressure.
But because it is a very efficient medicine in the treatment of depression, this medicine returned to the market. However, when prescribed the doctor will prohibit the patient from eating a number of foods and taking some medications that may interact with MAOI in a bad way.
By reading about what Bob's doctor prescribed about which foods he could not eat and what medications he could not take, so as not to affect the functioning of his medicine, we can say that Bob was being treated with MAOIs.
