Quizplus · Accepted Answer

The two major classes of antidepressant drugs are MAO inhibitors and tricyclics. Benzodiazepines are not typically classified as antidepressants and are instead used to treat anxiety. Lithium is primarily used to treat bipolar disorder. MAOIs and tricyclics work by regulating levels of neurotransmitters such as serotonin and norepinephrine in the brain, which are often imbalanced in individuals with depression.
