Talk:Antidepressant
An antidepressant is a type of psychiatric drug used for treating major depressive disorder (unipolar depression). It is worth noting that many of these agents are not effective for bipolar disorder-associated depression and that antipsychotics such as lurasidone (Latuda) and quetiapine (Seroquel) are used for this purpose.
Types of antidepressants
Selective serotonin reuptake inhibitors (SSRIs)
- Selective serotonin reuptake inhibitors are believed to increase the level of extracellular serotonin, therefore allowing more serotonin to be in the brain. The reason SSRIs are used for depression is because . SSRIs are the most commonly prescribed anti depressant, and the most commonly prescribed anxiolytic for children.
Selective serotonin reuptake enhancers (SSREs)
Serotonin-norepinephrine reuptake inhibitor (SNRIs)
Serotonin modulators and stimulators (SMSes)
Serotonin antagonists and reuptake inhibitors (SARIs)
Norepinephrine reuptake inhibitors (NRIs)
- NRIs are believed to increase the level of extracellular norepinephrine, therefore allowing more of it to be in the brain. Controversy has been sparked over the effectiveness of reboxetine, an NRI sold as Trintellix. [1]
Norepinephrine-dopamine reuptake inhibitors (NDRIs)
- NDRIs are believed to increase the level of extracellular norepinephrine and dopamine, therefore allowing more of these to be in the brain. Agents such as bupropion (Wellbutrin) have been found effective for MDD with little direct effect on serotonin, and therefore it can be hypothesized that other agents are effective for it. Bupropion and other NDRIs are also effective for depression with fatigue or sleepiness.
Tricyclic antidepressants (TCAs)
Tetracyclic antidepressants (TeCAs)
Monoamine Oxidase Inhibitors (MAOIs)
MAOIs are usually prescribed when no other antidepressants are helping. This is because MAOIs require diet changes and have a very large amount of side effects.[2]
Psychedelics for treating depression
Psilocybin mushrooms ("magic mushrooms")
In clinical studies, ketamine has proven to be an extremely effective and fast acting antidepressant at low doses (compared to common recreational doses).[3] It has become increasingly common for doctors to prescribe ketamine for treatment-resistant and severe depression.
Because dextromethorphan can show similar anti-depressant effects to ketamine in low doses (compared to common recreational doses), it is possible that dextromethorphan could be a possible treatment for treatment resistant and severe depression. Many users of dextromethorphan claim that they do not feel any depression within a week of using dextromethorphan.
