Antidepressants In Japan
The number of new psychiatric drugs, and especially antidepressants on the market in Japan, is significantly less than Western countries. One of the biggest barriers to antidepressants coming to the market is that the medical insurance system in Japan is national, and the authorities are keen to contain a potentially explosive market for drugs like antidepressants that could be used or abused by persons in various forms of distress. Although large epidemiological studies have not been done in Japan, it is thought that up to 6 million Japanese suffer from depression, with a lifetime prevalence of 13 to 17.3%, which is similar to that seen in Western countries. Market While the market has seen the entry of selective serotonin reuptake inhibitors (SSRIs) fluvoxamine, paroxetine, sertraline, and escitalopram; others such as citalopram and fluoxetine are either pending approval or no longer being considered. Prior to year 2000 and possibly even later, clinical developments did not u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Psychiatric Medication
A psychiatric or psychotropic medication is a psychoactive drug taken to exert an effect on the chemical makeup of the brain and nervous system. Thus, these medications are used to treat mental illnesses. These medications are typically made of synthetic chemical compounds and are usually prescribed in psychiatric settings, potentially involuntarily during commitment. Since the mid-20th century, such medications have been leading treatments for a broad range of mental disorders and have decreased the need for long-term hospitalization, thereby lowering the cost of mental health care. The recidivism or rehospitalization of the mentally ill is at a high rate in many countries, and the reasons for the relapses are under research. History Several significant psychiatric drugs were developed in the mid-20th century. In 1948, lithium was first used as a psychiatric medicine. One of the most important discoveries was chlorpromazine, an antipsychotic that was first given to a patie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fluvoxamine
Fluvoxamine, sold under the brand name Luvox and Faverin among others, is an antidepressant of the selective serotonin reuptake inhibitor (SSRI) class. It is primarily used to treat major depressive disorder and obsessive–compulsive disorder (OCD), but is also used to treat anxiety disorders such as panic disorder, social anxiety disorder, and post-traumatic stress disorder. Fluvoxamine's side-effect profile is very similar to other SSRIs: constipation, gastrointestinal problems, headache, anxiety, irritation, sexual problems, dry mouth, sleep problems and a risk of suicide at the start of treatment by lifting the psychomotor inhibition, but these effects appear to be significantly weaker than with other SSRIs (except gastrointestinal side-effects). The tolerance profile is superior in some respects to other SSRIs, particularly with respect to cardiovascular complications, despite its age. It is on the World Health Organization's List of Essential Medicines. Medical uses ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bupropion
Bupropion, sold under the brand names Wellbutrin and Zyban among others, is an atypical antidepressant primarily used to treat major depressive disorder and to support smoking cessation. It is also popular as an add-on medication in the cases of "incomplete response" to the first-line selective serotonin reuptake inhibitor (SSRI) antidepressant. Bupropion has several features that distinguish it from other antidepressants: it does not usually cause sexual dysfunction; it is not associated with weight gain and sleepiness, and it is more effective than SSRIs at improving symptoms of hypersomnia and fatigue. Bupropion does, however, carry a much higher risk of seizure than many other antidepressants and extreme caution must be taken in patients with a history of seizure disorder. Common adverse effects of bupropion with the greatest difference from placebo are dry mouth, nausea, constipation, insomnia, anxiety, tremor, and excessive sweating. Raised blood pressure is notable. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Enantiomer
In chemistry, an enantiomer ( /ɪˈnænti.əmər, ɛ-, -oʊ-/ ''ih-NAN-tee-ə-mər''; from Ancient Greek ἐνάντιος ''(enántios)'' 'opposite', and μέρος ''(méros)'' 'part') – also called optical isomer, antipode, or optical antipode – is one of two stereoisomers that are non-superposable onto their own mirror image. Enantiomers are much like one's right and left hands, when looking at the same face, they cannot be superposed onto each other. No amount of reorientation will allow the four unique groups on the chiral carbon (see Chirality (chemistry)) to line up exactly. The number of stereoisomers a molecule has can be determined by the number of chiral carbons it has. Stereoisomers include both enantiomers and diastereomers. Diastereomers, like enantiomers, share the same molecular formula and are non-superposable onto each other however, they are not mirror images of each other. A molecule with chirality rotates plane-polarized light. A mixture of equals ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Escitalopram
Escitalopram, sold under the brand names Lexapro and Cipralex, among others, is an antidepressant of the selective serotonin reuptake inhibitor (SSRI) class. Escitalopram is mainly used to treat major depressive disorder and generalized anxiety disorder. It is taken by mouth, available commercially as an oxalate salt exclusively. Common side effects include trouble sleeping, nausea, sexual problems, and feeling tired. More serious side effects may include suicidal thoughts in people up to the age of 24 years. It is unclear if use during pregnancy or breastfeeding is safe. Escitalopram is the (''S'')-enantiomer of citalopram (which exists as a racemate), hence the name ''es''-citalopram. Escitalopram was approved for medical use in the United States in 2002. Escitalopram is rarely replaced by twice the dose of citalopram, though escitalopram is safer and more effective. It is on the World Health Organization's List of Essential Medicines. In 2020, it was the fifteenth most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Citalopram
Citalopram, sold under the brand name Celexa among others, is an antidepressant of the selective serotonin reuptake inhibitor (SSRI) class. It is used to treat major depressive disorder, obsessive compulsive disorder, panic disorder, and social phobia. The antidepressant effects may take one to four weeks to occur. It is taken by mouth. Common side effects include nausea, trouble sleeping, sexual problems, shakiness, feeling tired, and sweating. Serious side effects include an increased risk of suicide in those under the age of 25, serotonin syndrome, glaucoma, and QT prolongation. It should not be used in persons who take or have recently taken a MAO inhibitor. Antidepressant discontinuation syndrome may occur when stopped. There are concerns that use during pregnancy may harm the fetus. Citalopram was approved for medical use in the United States in 1998. It is on the World Health Organization's List of Essential Medicines. It is available as a generic medication. In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Duloxetine
Duloxetine, sold under the brand name Cymbalta among others, is a medication used to treat major depressive disorder, generalized anxiety disorder, fibromyalgia, neuropathic pain and central sensitization. It is taken by mouth. It is a serotonin–norepinephrine reuptake inhibitor. Common side effects include dry mouth, nausea, feeling tired, dizziness, agitation, sexual problems, and increased sweating. Severe side effects include an increased risk of suicide, serotonin syndrome, mania, and liver problems. Antidepressant withdrawal syndrome may occur if stopped. There are concerns that use during the later part of pregnancy can harm the developing fetus. Similarly to SSRIs and other SNRIs, a precise mechanism for duloxetine's antidepressant and anxiolytic effects is not known. Duloxetine was approved for medical use in the United States and in the European Union in 2004. It is available as a generic medication. In 2020, it was the 27th most commonly prescribed medicatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Major Depressive Disorder
Major depressive disorder (MDD), also known as clinical depression, is a mental disorder characterized by at least two weeks of pervasive low mood, low self-esteem, and loss of interest or pleasure in normally enjoyable activities. Introduced by a group of US clinicians in the mid-1970s, the term was adopted by the American Psychiatric Association for this symptom cluster under mood disorders in the 1980 version of the '' Diagnostic and Statistical Manual of Mental Disorders'' (DSM-III), and has become widely used since. The diagnosis of major depressive disorder is based on the person's reported experiences, behavior reported by relatives or friends, and a mental status examination. There is no laboratory test for the disorder, but testing may be done to rule out physical conditions that can cause similar symptoms. The most common time of onset is in a person's 20s, with females affected about twice as often as males. The course of the disorder varies widely, from one e ...

Mirtazapine
Mirtazapine, sold under the brand name Remeron amongst others, is an atypical antidepressant, and as such is used primarily to treat depression. Its effects may take up to four weeks, but can also manifest as early as one to two weeks. It is often used in cases of depression complicated by anxiety or insomnia. The effectiveness of mirtazapine is comparable to other commonly prescribed antidepressants. It is taken by mouth. Common side effects include sleepiness, dizziness, increased appetite and weight gain. Serious side effects may include mania, low white blood cell count, and increased suicide among children. Withdrawal symptoms may occur with stopping. It is not recommended together with a monoamine oxidase inhibitor, although evidence supporting the danger of this combination has been refuted. It is unclear if use during pregnancy is safe. How it works is not clear, but it may involve blocking certain adrenergic and serotonin receptors. Chemically, it is a tetrac ...
