What are the drugs for treating depression?

There are many drugs for depression. Traditionally, there are tricyclic drugs and tetracyclic drugs, tricyclic drugs amitriptyline and doxepin, and tetracyclic drugs maprotiline. These drugs have great side effects or take a long time to take effect, often taking three to four weeks, and are rarely used in clinic. At present, we commonly use serotonin reuptake inhibitors, that is, we often say "five golden flowers", paroxetine, Prozac, citalopram, sertraline and fluvoxamine. This kind of medicine has less side effects and faster action time, which can take effect in about two to three weeks. At present, most of them use this medicine. At the same time, there are drugs with double inhibition, such as serotonin and norepinephrine, such as venlafaxine.
