Selective serotonin reuptake inhibitors MAOIs

SSRI, selective serotonin reuptake inhibitor MAOI, monoamine oxidase inhibitor. 

TCA, tricyclic antidepressant SSRI, selective serotonin reuptake inhibitor MAOI, monoamine oxidase inhibitor. 0, no effect +, + +, + + + indicate increasing effect. 

Drugs that may affect methylphenidate include MAOIs. Drugs that may be affected by methylphenidate hydrochloride include guanethidine, anticonvulsants (eg, phenytoin, phenobarbital, primidone), selective serotonin reuptake inhibitors, coumarin anticoagulants, and tricyclic antidepressants. 

The field of antidepressant research was revolutionized in the late 1980s by the introduction of selective serotonin reuptake inhibitors (SSRIs), exemplified by fluoxetine (9). In addition to their antidepressant action, SSRIs have also proven effective for a broad range of psychiatric illnesses, and, more importantly, they demonstrated an improved tolerability profile as compared to TCAs and MAOIs due to their increased selectivity. On the other hand, SSRIs proved inferior to TCAs and MAOIs in their reduced antidepressant effects, slower onset of action, lower remission rates, and decreased ability to control the physical symptoms associated with depression. 

The growth during the 1990s in the use of antidepressants, particularly selective serotonin reuptake inhibitors (SSRIs), for the treatment of anxiety disorders represented a major advance in the pharmacotherapy of anxiety. The efficacy of tricyclic antidepressants (TCAs) and monoamine oxidase inhibitors (MAOIs) had been established alongside their antidepressantw actions several decades...

Over the next 20 years, the benzodiazepines, TCAs, MAOIs, and beta-blockers were used to treat anxiety disorders. By the mid-1980s, up to 10% of all Americans were taking a benzodiazepine. In 1988, fluoxetine (Prozac) was introduced by Eli Lilly as the first selective serotonin reuptake inhibitor (SSRI) for the treatment of mood and anxiety disorders. Its success led to the development of several other SSRI drugs. Today, these drugs are the first line of drug treatment for most anxiety disorders. 

In contrast, a less extensive but still convincing database has identified important clinical differences in efficacy for antidepressants used to treat patients with atypical or comorbid depression. Individuals with atypical depression (distinct quality of mood, hyperphagia, hypersomnia, psychomotor retardation, rejection sensitivity, and such unusual atypical features as chocolate craving] have superior responses to monoamine oxidase inhibitors (MAOIs], selective serotonin reuptake inhibitors (SSRIs), and perhaps venlafaxine, and most do not respond well to tricyclic antidepressants (TCAs] (Davidson et al. 1982 Liebowitz et al. 1988 Quitkin et al. 1988, 1991). Despite these data, TCAs unfortunately have been the first choice for most atypical patients until SSRIs were introduced.

MAOIs are commonly associated with treatment-emergent sexual dysfunction, including decreased libido, delayed ejaculation, anor-gasmia, and impotence. Some patients become tolerant to this side effect over time, but more often the problem persists unless the dose is reduced or another medication is used to counter the sexual side effects. The treatment of sexual side effects is discussed in the Selective Serotonin Reuptake Inhibitors section earlier in this chapter.

We have provided a summary of the results from double-blind, random-assignment studies (usually class I or II designs) comparing HCAs, selective serotonin reuptake inhibitors (SSRIs), other new antidepressants, and MAOIs with placebo or with each other for the acute treatment of depression. Each study was reviewed, and a global judgment made, based on all the evidence presented, as to whether a given drug was more effective than placebo or another control therapy.

Selective serotonin reuptake inhibitors (SSRIs) [P] Fatalities have occurred due to serotonin syndrome contraindicated in patients taking MAOIs. 

Antidepressants were first introduced into the market in the 1950s with the serendipitous discovery of the antidepressant effect of two drugs initially evaluated for other medical uses Iproniazide, a monoamine oxidase inhibitor (MAOI), and Imipramine, a tricyclic antidepressant (TCA). Since then, a whole new generation of chemically and pharmacologically unrelated compounds have been introduced, which appear to be safer and better tolerated due to a more specific mechanism of action. These include selective serotonin reuptake inhibitors (SSRIs), serotonin and... 

St. John s wort also exhibits anti-inflammatory and antibacterial activity. Reports of antiviral activity arc unsubstantiated. The main adverse effect with St. John s wort is severe phototoxicity. A sunbum-like condition may occur at normal dosages. St. John s wort. should never be taken with MAOIs because of the risk of potentiation of the effects. Selective serotonin reuptake inhibitors (SSRIs) likewise should not be taken with St. John s wort because of the ri.sk of serotonergic syndrome. 

MAOI and SSRI are acronyms for two types of antidepression medication. MAOI stands for monoamine oxidase inhibitor. MAOIs must be prescribed and used with caution because they tend to dangerously interact with other types of drugs.Today, other forms of antidepressants are usually prescribed for depression patients first. If those medicines do not work, MAOIs are sometimes used with caution. People taking MAOIs have to restrict their diets and watch what other drugs and medicines they take in order to prevent interactions. SSRI, an antidepressant that is more commonly used, stands for selective serotonin reuptake inhibitor.They are generally able to be tolerated by more people and can be used for more minor depressive illnesses.
