Nomifensine
Nomifensine, formerly sold under the brand names Merital and Alival, is a norepinephrine–dopamine reuptake inhibitor (NDRI) drug that was developed in the 1960s by Hoechst AG (now Sanofi-Aventis), who then test marketed it in the United States. Nomifensine was considered an effective antidepressant that lacked sedative effects. It did not interact significantly with alcohol (drug), alcohol and lacked anticholinergic effects. No Drug withdrawal, withdrawal symptoms were seen after 6 months treatment. The drug was, however, considered not suitable for agitated patients as it presumably made agitation worse. In January 1986 the drug was withdrawn by its manufacturers for safety reasons. Some case reports in the 1980s suggested that there was potential for psychological dependence on nomifensine, typically in patients with a history of stimulant addiction, or when the drug was used in very high doses (400–600 mg per day). In a 1989 study it was investigated for use in tre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pro-motivational Agent
A motivation-enhancing drug, also known as a pro-motivational drug, is a drug which increases motivation. Drugs enhancing motivation can be used in the treatment of motivational deficits, for instance in depression, schizophrenia, and attention deficit hyperactivity disorder (ADHD). They can also be used in the treatment of disorders of diminished motivation (DDMs), including apathy, abulia, and akinetic mutism, disorders that can be caused by conditions like stroke, traumatic brain injury (TBI), and neurodegenerative diseases. Motivation-enhancing drugs are used non-medically by healthy people to increase motivation and productivity as well, for instance in educational contexts. There are limited clinical data on medications in treating motivational deficits and disorders. In any case, drugs used for pro-motivational purposes are generally dopaminergic agents, for instance dopamine reuptake inhibitors (DRIs) like methylphenidate and modafinil, dopamine releasing agents (DRA ...

Antidepressant
Antidepressants are a class of medications used to treat major depressive disorder, anxiety disorders, chronic pain, and addiction. Common side effects of antidepressants include Xerostomia, dry mouth, weight gain, dizziness, headaches, akathisia, sexual dysfunction, and emotional blunting. There is an increased risk of Suicidal ideation, suicidal thinking and Suicide, behavior when taken by children, adolescents, and young adults. Antidepressant discontinuation syndrome, Discontinuation syndrome, which resembles recurrent Depression (mood), depression in the case of the Selective serotonin reuptake inhibitor, SSRI class, may occur after stopping the intake of any antidepressant. Research regarding the effectiveness of antidepressants for depression in adults is controversial and has found both benefits and drawbacks. Meanwhile, evidence of benefit in children and adolescents is unclear, even though antidepressant use has considerably increased in children and adolescents in th ...

Diário Oficial Da União
The ''Diário Oficial da União'' (literally ''Official Diary of the Union''), abbreviated DOU, is the government gazette, official gazette of the Federal Government of Brazil, Federal Government of Brazil. It is published since 1 October 1862 and was created via the Imperial Decree 1,177 of its 9 September as the ''Official Journal of the Empire of Brazil''. Its current name was adopted after Brazil became a federal republic, and the "Union" came into being as the legal personality of the new federal government. The official journal is published by the Imprensa Nacional, Brazilian National Press. Though the journal has been published since 1862, it had many predecessors, as follows: # Gazeta do Rio de Janeiro (10/9/1808 – 29.12.1821) # Gazeta do Rio (1/1/1822 – 31/12/1822) # Diário do Governo (2/1/1823 – 28/6/1833) # Diário Fluminense (21/5/1824 – 24/4/1831) # Correio Oficial (1/7/1833 – 30/6/1836) e (2/1/1830 – 30/12/1840) # Without proper journal (31/12/1840 – ...

Xerostomia
Xerostomia, also known as dry mouth, is a subjective complaint of dryness in the mouth, which may be associated with a change in the composition of saliva, reduced salivary flow, or have no identifiable cause. This symptom is very common and is often seen as a side effect of many types of medication. It is more common in older people (mostly because individuals in this group are more likely to take several medications) and in people who breathe through their mouths. Dehydration, radiotherapy involving the salivary glands, chemotherapy and several diseases can cause reduced salivation (hyposalivation), or a change in saliva consistency and hence a complaint of xerostomia. Sometimes there is no identifiable cause, and there may sometimes be a psychogenic reason for the complaint. Definition Xerostomia is the subjective sensation of dry mouth, which is often (but not always) associated with hypofunction of the salivary glands. The term is derived from the Greek words ξηρός (' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bupropion
Bupropion, formerly called amfebutamone, and sold under the brand name Wellbutrin among others, is an atypical antidepressant that is indicated in the treatment of major depressive disorder, seasonal affective 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, particularly the immediate-release formulation, carries a higher risk of seizure than many other antidepressants, hence caution is recommended in patients with a history of seizure disorder. The medication is taken by mouth. Common adverse effects of bupropion with the greatest difference fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Motivational Disorder
Disorders of diminished motivation (DDM) are a group of disorders involving diminished motivation and associated emotions. Many different terms have been used to refer to diminished motivation. Often however, a spectrum is defined encompassing apathy, abulia, and akinetic mutism, with apathy the least severe and akinetic mutism the most extreme. DDM can be caused by psychiatric disorders like depression and schizophrenia, brain injuries, strokes, and neurodegenerative diseases. Damage to the anterior cingulate cortex and to the striatum, which includes the nucleus accumbens and caudate nucleus and is part of the mesolimbic dopamine reward pathway, have been especially associated with DDM. Diminished motivation can also be induced by certain drugs, including antidopaminergic agents like antipsychotics, selective serotonin reuptake inhibitors (SSRIs), and cannabis, among others. DDM can be treated with dopaminergic and other activating medications, such as dopamine reuptake ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tetrabenazine
Tetrabenazine is a drug for the symptomatic treatment of hyperkinetic movement disorders. It is sold under the brand names Nitoman and Xenazine among others.

Catalytic Hydrogenation
Hydrogenation is a chemical reaction between molecular hydrogen (H2) and another compound or element, usually in the presence of a catalyst such as nickel, palladium or platinum. The process is commonly employed to reduce or saturate organic compounds. Hydrogenation typically constitutes the addition of pairs of hydrogen atoms to a molecule, often an alkene. Catalysts are required for the reaction to be usable; non-catalytic hydrogenation takes place only at very high temperatures. Hydrogenation reduces double and triple bonds in hydrocarbons. Process Hydrogenation has three components, the unsaturated substrate, the hydrogen (or hydrogen source) and, invariably, a catalyst. The reduction reaction is carried out at different temperatures and pressures depending upon the substrate and the activity of the catalyst. Related or competing reactions The same catalysts and conditions that are used for hydrogenation reactions can also lead to isomerization of the alkenes fro ...
