Harmine and harmaline are selective and reversible inhibitors of monoamine oxidase A ( MAO-A ), while tetrahydroharmine is a weak serotonin reuptake inhibitor ( SRI ).

Drugs including the monoamine oxidase inhibitors ( MAOIs ), tricyclic antidepressants ( TCAs ), tetracyclic antidepressants ( TeCAs ), selective serotonin reuptake inhibitors ( SSRIs ), and serotonin-norepinephrine reuptake inhibitors ( SNRIs ) are most commonly associated with the term.

Selective serotonin reuptake inhibitors ( SSRIs ) are the class of antidepressants commonly used as the first-line treatment for depression because they have a favorable side effect profile and low toxicity.

Changing the balance of serotonin and norepinephrine would help the brain cells send and receive messages, therefore boosting the mood, which also is the main reason why these types of medications are called dual reuptake inhibitors.

When a hypothetical dilemma was given to 24 people and according to the dilemma they had the capability of pushing a stranger in front of a train so they could rescue five people, individuals who had taken selective serotonin reuptake inhibitors were not as likely to support the idea of pushing the person.

Norepinephrine reuptake inhibitors ( NRIs ) act via norepinephrine ( noradrenaline ).

Norepinephrine-dopamine reuptake inhibitors inhibit the neuronal reuptake of dopamine and norepinephrine.

Selective serotonin reuptake inhibitors or serotonin-specific reuptake inhibitor ( SSRIs ) are a class of compounds typically used as antidepressants in the treatment of depression, anxiety disorders, and some personality disorders.

The views range from those that hold that benzodiazepines are not effective long-term and that they should be reserved for treatment-resistant cases to that they are as effective in the long term as selective serotonin reuptake inhibitors.

The choice of treatment between benzodiazepines, SSRIs, serotonin – norepinephrine reuptake inhibitors, tricyclic antidepressants, and psychotherapy should be based on the patient's history, preference, and other individual characteristics.

Selective serotonin reuptake inhibitors are likely to be the best choice of pharmacotherapy for many patients with panic disorder, but benzodiazepines are also often used, and some studies suggest that these medications are still used with greater frequency than the SSRIs.

There has been further work to suggest that neuropathic pain localized in the pelvic region may respond to neurotransmitter reuptake inhibitors.

Because of potentially lethal dietary and drug interactions, monoamine oxidase inhibitors have historically been reserved as a last line of treatment, used only when other classes of antidepressant drugs ( for example selective serotonin reuptake inhibitors and tricyclic antidepressants ) have failed.

In recent times, the TCAs have been largely replaced in clinical use in most parts of the world by newer antidepressants such as the selective serotonin reuptake inhibitors ( SSRIs ) and serotonin-norepinephrine reuptake inhibitors ( SNRIs ), which typically have more favorable side-effects profiles, though they are still sometimes prescribed for certain indications.

The majority of the TCAs act primarily as serotonin-norepinephrine reuptake inhibitors ( SNRIs ) by blocking the serotonin transporter ( SERT ) and the norepinephrine transporter ( NET ), respectively, which results in an elevation of the synaptic concentrations of these neurotransmitters, and therefore an enhancement of neurotransmission.

Discontinuation of selective serotonin reuptake inhibitors ( SSRIs ), the most commonly prescribed class of antidepressants, ( and the related class serotonin-norepinephrine reuptake inhibitors or SNRIs ) is associated with a particular syndrome of physical and psychological symptoms known as SSRI discontinuation syndrome.

In a major systematic review published in 2009 which compared the efficacy and tolerability of 12 popular antidepressants, mirtazapine was found to be superior to all of the included selective serotonin reuptake inhibitors ( SSRIs ) and serotonin-norepinephrine reuptake inhibitors ( SNRIs ), and reboxetine, bupropion, and mianserin in terms of antidepressant efficacy, while it was average in regards to tolerability.

The different kinds of medicines that can be taken to treat attention deficit ( hyperactivity ) disorder include central nervous system stimulants, antidepressants, antihypertensives, and selective norepinephrine reuptake inhibitors ( SNRIs ).

Serotonin – norepinephrine reuptake inhibitors ( SNRIs ) are a class of antidepressant drugs used in the treatment of major depression and other mood disorders.

" SNRIs work by inhibiting the reuptake of the neurotransmitters serotonin and norepinephrine.

Most SNRIs function alongside primary metabolites and secondary metabolites in order to inhibit reuptake of serotonin, norepinepherine, and trace amounts of dopamine.

Tricyclic and dual serotonergic-noradrenergic reuptake inhibition by SNRIs ( or SSRI-NRI combinations ), have also shown analgesic properties additionally.

There is the potential for life-threatening serotonin syndrome ( a syndrome of changes in mental status, autonomic instability, neuromuscular abnormalities, and gastrointestinal symptoms ) in patients taking triptans and selective serotonin reuptake inhibitors ( SSRIs ) or selective serotonin / norepinephrine reuptake inhibitors ( SNRIs ) at the same time .< ref name =' FDA ALERT :'>

Some studies indicate that serotonin-norepinephrine reuptake inhibitors ( SNRIs ) such as venlafaxine ( Effexor ) and duloxetine ( Cymbalta ) are even more effective.

* commonly prescribed antidepressants such as the selective serotonin reuptake inhibitors ( SSRIs ) and serotonin-norepinephrine reuptake inhibitors ( SNRIs ) ( cf.

SNRIs affect both reuptake inhibition of serotonin and norepinephrine.

During marketing of other SSRIs and SNRIs ( serotonin and norepinephrine reuptake inhibitors ), there have been spontaneous reports of adverse events occurring upon discontinuation of these drugs, particularly when abrupt, including the following: dysphoric mood, irritability, agitation, aggressiveness, dizziness, sensory disturbances ( e. g., paresthesias such as electric shock sensations ), anxiety, confusion, headache, lethargy, emotional lability, insomnia, hypomania, tinnitus, and seizures.

SSRIs are said to work by preventing the reuptake of serotonin ( also known as 5-hydroxytryptamine, or 5-HT ) by the presynaptic neuron, thus maintaining higher levels of 5-HT in the synapse.

The TCAs include the following agents which are predominantly serotonin and / or norepinephrine reuptake inhibitors:

In the prefrontal cortex, however, there are very few DAT proteins, and dopamine is inactivated instead by reuptake via the norepinephrine transporter ( NET ), presumably on neighboring norepinephrine neurons, then enzymatic breakdown by COMT into 3-MT.

Such drugs are called selective serotonin reuptake inhibitors ( SSRIs ), and they actively prevent these neurotransmitters from dropping to the levels at which depression is experienced.

TCAs as a group are considered to work better than selective serotonin reuptake inhibitors for melancholic depression and in inpatients ,< ref name =" pmid9597346 "> but not necessarily for simply more severe depression.

Recent scientific studies have shown that cognitive behavioral therapy ( CBT ) and selective serotonin reuptake inhibitors ( SSRIs ; e. g., fluoxetine and paroxetine ) are effective treatment options for hypochondriasis as demonstrated in clinical trials.

During investigation, it was revealed that Nishizawa had taken a large dose of SSRI medication ( SSRI ( Selective serotonin reuptake inhibitors ) are antidepressants used in the treatment of depression ) before the episode, and he said that he hijacked the plane because he wanted to fly it under the Rainbow Bridge in Tokyo.

* Selective serotonin reuptake inhibitor anti-depressants ( SSRIs ), because of their serotonergic effect, would seem to help IBS, especially patients who are constipation predominant.

Medical interventions are primarily concerned with hormonal intervention and use of selective serotonin reuptake inhibitors ( SSRIs ).

The most commonly used drugs are tricyclic antidepressants and selective serotonin reuptake inhibitors ( SSRI ’ s ).
