Why is mechanism of action important in antidepressant treatment?
Abstract:
Antidepressants are one of the most common treatment strategies for patients diagnosed with major depressive disorder (MDD). However, antidepressant medications have different mechanisms of action that can theoretically and in practice affect how patients respond. Clinicians should assess their patients' symptoms and response to medication at every visit to determine whether or not the treatment is fully effective. Here, follow the case of Maria, a 42-year-old teacher who is experiencing her first depressive episode.

One mechanism involves depleting stored catecholamines by displacing them from synaptic vesicles. These agents, known as "displacers," are transported into vesicles at the expense of noradrenaline. Examples include amphetamine and tyramine, which lack a catechol moiety, resulting in prolonged action, improved oral...
