Second-generation Antidepressant
The second-generation antidepressants are a class of antidepressants characterized primarily by the era of their introduction, approximately coinciding with the 1970s and 1980s, rather than by their chemical structure or by their pharmacological effect. As a consequence, there is some controversy over which treatments actually belong in this class. The term "third generation antidepressant" is sometimes used to refer to newer antidepressants, from the 1990s and 2000s, often selective serotonin reuptake inhibitors (SSRIs) such as; fluoxetine (Prozac), paroxetine (Paxil) and sertraline (Zoloft), as well as some non-SSRI antidepressants such as mirtazapine, nefazodone, venlafaxine, duloxetine and reboxetine. However, this usage is not universal. Examples This list is not exhaustive, and different sources vary upon which items should be considered second-generation. * Amineptine * Amoxapine * Bupropion * Iprindole * Maprotiline * Medifoxamine * Mianserin * Nomifensine * Tianeptine * ...

Mood Disorder
A mood disorder, also known as an affective disorder, is any of a group of conditions of mental and behavioral disorder where a disturbance in the person's mood is the main underlying feature. The classification is in the ''Diagnostic and Statistical Manual of Mental Disorders'' (DSM) and International Classification of Diseases (ICD). Mood disorders fall into seven groups, including; abnormally elevated mood, such as mania or hypomania; depressed mood, of which the best-known and most researched is major depressive disorder (MDD) (alternatively known as clinical depression, unipolar depression, or major depression); and moods which cycle between mania and depression, known as bipolar disorder (BD) (formerly known as manic depression). There are several sub-types of depressive disorders or psychiatric syndromes featuring less severe symptoms such as dysthymic disorder (similar to MDD, but longer lasting and more persistent, though often milder) and cyclothymic disorder (simila ...

Maprotiline
Maprotiline, sold under the brand name Ludiomil among others, is a tetracyclic antidepressant (TeCA) that is used in the treatment of depression. It may alternatively be classified as a tricyclic antidepressant (TCA), specifically a secondary amine. In terms of its chemistry and pharmacology, maprotiline is closely related to other secondary amine TCAs like nortriptyline and protriptyline, and has similar effects to them. Medical uses Maprotiline is used in the treatment of depression, such as depression associated with agitation or anxiety and has similar efficacy to the antidepressant drug moclobemide. * Treatment of depression of all forms and severities ( endogenous, psychotic, involutional, and neurotic) especially for depression associated with agitation or anxiety * Panic disorder * Neuropathic pain * Treatment of the depressive phase in bipolar depression * For the symptomatic relief of anxiety, tension or insomnia The use of maprotiline in the treatment of enuresi ...

Serotonin–norepinephrine Reuptake Inhibitor
Serotonin–norepinephrine reuptake inhibitors (SNRIs) are a class of antidepressant drugs used to treat major depressive disorder (MDD), anxiety disorders, obsessive–compulsive disorder (OCD), social phobia, attention-deficit hyperactivity disorder (ADHD), chronic neuropathic pain, fibromyalgia syndrome (FMS), and menopausal symptoms. SNRIs are monoamine reuptake inhibitors; specifically, they inhibit the reuptake of serotonin and norepinephrine. These neurotransmitters are thought to play an important role in mood regulation. SNRIs can be contrasted with the more widely used selective serotonin reuptake inhibitors (SSRIs), which act upon serotonin only. The human serotonin transporter (SERT) and noradrenaline transporter (NAT) are membrane transport proteins that are responsible for the reuptake of serotonin and noradrenaline from the synaptic cleft back into the presynaptic nerve terminal. Dual inhibition of serotonin and noradrenaline reuptake can offer advantages over othe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tetracyclic Antidepressant
Tetracyclic antidepressants (TeCAs) are a class of antidepressants that were first introduced in the 1970s. They are named after their tetracyclic chemical structure, containing four rings of atoms, and are closely related to the tricyclic antidepressants (TCAs), which contain three rings of atoms. List of TeCAs Marketed * Maprotiline (Ludiomil) – can also be classified as a TCA and grouped with the secondary amines * Mianserin (Tolvon) * Mirtazapine (Remeron) * Setiptiline (Tecipul) Drugs that contain four rings not all fused together but are sometimes still classified as TeCAs include: * Amoxapine (Asendin) – often classified as a TCA and grouped with the secondary amines * Quetiapine (Seroquel) - an atypical antipsychotic sometimes used as an adjunct antidepressant Miscellaneous * Benzoctamine (Tacitin) – a tetracyclic compound and is closely related to maprotiline, with the two compounds differing only in the length of their side chain, but benzoctamine is not us ...

Tricyclic Antidepressant
Tricyclic antidepressants (TCAs) are a class of medications that are used primarily as antidepressants, which is important for the management of depression. They are second-line drugs next to SSRIs. TCAs were discovered in the early 1950s and were marketed later in the decade. They are named after their chemical structure, which contains three rings of atoms. Tetracyclic antidepressants (TeCAs), which contain four rings of atoms, are a closely related group of antidepressant compounds. Although TCAs are sometimes prescribed for depressive disorders, they have been largely replaced in clinical use in most parts of the world by newer antidepressants such as selective serotonin reuptake inhibitors (SSRIs), serotonin–norepinephrine reuptake inhibitors (SNRIs) and norepinephrine reuptake inhibitors (NRIs). Adverse effects have been found to be of a similar level between TCAs and SSRIs. Another class of antidepressants, tetracyclic antidepressants, are also used around the world, a ...

Pharmacology Of Antidepressants
Pharmacology is a branch of medicine, biology and pharmaceutical sciences concerned with drug or medication action, where a drug may be defined as any artificial, natural, or endogenous (from within the body) molecule which exerts a biochemical or physiological effect on the cell, tissue, organ, or organism (sometimes the word ''pharmacon'' is used as a term to encompass these endogenous and exogenous bioactive species). More specifically, it is the study of the interactions that occur between a living organism and chemicals that affect normal or abnormal biochemical function. If substances have medicinal properties, they are considered pharmaceuticals. The field encompasses drug composition and properties,functions,sources,synthesis and drug design, molecular and cellular mechanisms, organ/systems mechanisms, signal transduction/cellular communication, molecular diagnostics, interactions, chemical biology, therapy, and medical applications and antipathogenic capabilities ...

Development And Discovery Of SSRI Drugs
Selective serotonin reuptake inhibitors, or serotonin-specific re-uptake inhibitor (SSRIs), are a class of chemical compounds that have contributed to the major advances as antidepressants where they have revolutionised the treatment of depression and other psychiatric disorders. The SSRIs are therapeutically useful in the treatment of panic disorder (PD), posttraumatic stress disorder (PTSD), social anxiety disorder (also known as social phobia), obsessive-compulsive disorder (OCD), premenstrual dysphoric disorder (PMDD), and anorexia. There is also clinical evidence of SSRIs efficiency in the treatment of the negative symptoms of schizophrenia and their ability to prevent cardiovascular diseases. SSRIs primarily inhibit serotonin transporter (SERT) in the brain and have negligible effects on dopamine transporter (DAT) and norepinephrine transporter (NET). Inhibiting the binding of the neurotransmitter, serotonin (5-HT), to SERT results in increased 5-HT concentration in the synap ...

Atypical Antidepressant
An atypical antidepressant is any antidepressant medication that acts in a manner that is different from that of most other antidepressants. Atypical antidepressants include agomelatine, bupropion, iprindole, mianserin, mirtazapine, nefazodone, opipramol, tianeptine, and trazodone. The agents vilazodone and vortioxetine are partly atypical. Typical antidepressants include the , , , and , which act mainly by increasing the levels of the monoamine neurotransmitters serotonin and/or norepinephrine. Among TCAs, trimipramine is an atypical agent in that it appears not to do this. In August 2020, Esketamine (JNJ-54135419) was approved by the U.S. Food and Drug Administration (FDA) for the treatment for treatment-resistant depression with the added indication for the short-term treatment of suicidal thoughts. Buprenorphine/samidorphan (ALKS-5461) is an antidepressant with a novel mechanism of action which was formerly under development and considered an atypical antidepressant. They a ...

Viloxazine
Viloxazine, sold under the brand name Qelbree and formerly as Vivalan among others, is a noradrenergic medication which is used in the treatment of attention deficit hyperactivity disorder (ADHD) in children and adults. It was marketed for almost 30years as an antidepressant for the treatment of depression before being discontinued and subsequently repurposed as a treatment for ADHD. Viloxazine is taken by mouth. It was used as an antidepressant in an immediate-release form and is used in ADHD in an extended-release form. Side effects of viloxazine include insomnia, headache, somnolence, fatigue (medical), fatigue, nausea, vomiting, decreased appetite, dry mouth, constipation, irritability, increased heart rate, and increased blood pressure. Rarely, the medication may cause suicidal ideation, suicidal thoughts and suicidal behavior, behaviors. It can also activate mania or hypomania in people with bipolar disorder. Viloxazine acts as a binding selectivity, selective norepinephri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Venlafaxine
Venlafaxine, sold under the brand name Effexor among others, is an antidepressant medication of the serotonin-norepinephrine reuptake inhibitor (SNRI) class. It is used to treat major depressive disorder, generalized anxiety disorder, panic disorder, and social anxiety disorder. It may also be used for chronic pain. It is taken by mouth. It is also available as the salt venlafaxine besylate in an extended-release formulation (Venbysi XR). Common side effects include loss of appetite, constipation, dry mouth, dizziness, sweating, insomnia, drowsiness and sexual problems. Severe side effects include an increased risk of suicide, mania, and serotonin syndrome. Antidepressant withdrawal syndrome may occur if stopped. There are concerns that use during the later part of pregnancy can harm the baby. How it works is not entirely clear, but it seems to be related to the potentiation of the activity of some neurotransmitters in the brain. Venlafaxine was approved for medical use in t ...

Tianeptine
Tianeptine, sold under the brand names Stablon and Coaxil among others, is an atypical antidepressant which is used mainly in the treatment of major depressive disorder, although it may also be used to treat anxiety, asthma, and irritable bowel syndrome. Tianeptine has antidepressant and anxiolytic effects with a relative lack of sedative, anticholinergic, and cardiovascular side effects. It has been found to act as an atypical agonist of the μ-opioid receptor with clinically negligible effects on the δ- and κ-opioid receptors. Tianeptine was discovered and patented by the French Society of Medical Research in the 1960s. Currently, tianeptine is approved in France and manufactured and marketed by Laboratories Servier SA; it is also marketed in a number of other European countries under the trade name Coaxil as well as in Asia (including Singapore) and Latin America as Stablon and Tatinol but it is not available in Australia, Canada, New Zealand, or the United Kingdom.
