antidepressant action
In antidepressant SSRIs were introduced in the 1980s, and shortly thereafter they became some of the most commonly used antidepressants, primarily because they have fewer side effects than tricyclics or MAOIs. SSRIs include fluoxetine (Prozac), paroxetine (Paxil), and sertraline (Zoloft). SSRIs are also used in the treatment… Read More

This results in the buildup or accumulation of neurotransmitters in the brain and allows them… Read More

Other important groups include the norepinephrine reuptake inhibitors (NRIs), the serotonin-norepinephrine reuptake inhibitors (SNRIs), and the atypical antidepressants, a disparate group of agents that possess unique structural features and mechanisms of action.

types of antidepressant drugs
In therapeutics: Antidepressant drugs …selective serotonin reuptake inhibitors (SSRIs), monoamine oxidase inhibitors (MAOIs), and others that are often called heterocyclics (e.g., trazodone, bupropion). The SSRIs, such as fluoxetine (Prozac), sertraline, and paroxetine, have no sedating effect, anticholinergic activity, associated weight gain, or cardiac toxicity, but they can cause nervousness.

In mental disorder: Antidepressant agents Selective serotonin reuptake inhibitors (SSRIs), which include fluoxetine (Prozac) and sertraline (Zoloft), are thought to act by inhibiting the reabsorption of the neurotransmitter serotonin. As a result, there is an accumulation of serotonin in the brain, a change that may be important in elevating mood.… Read More
