They are second-line drugs next to SSRIs. The severe morbidity and mortality associated with these drugs is well documented due to their cardiovascular and neurological toxicity. Seit Jahrzehnten hält sich die Vorstellung, dass ein Defizit von Serotonin zu Depressionen führt. Nach oraler Gabe beträgt das scheinbare Verteilungsvolumen etwa 12 bis 26 l/kg. Many side effects may be related to the antimuscarinic properties of the TCAs. The story begins with the synthesis of chlorpromazine in December 1950 by Rhône-Poulenc's chief chemist, Paul Charpentier, from synthetic antihistamines developed by Rhône-Poulenc in the 1940s.[3] Its psychiatric effects were first noticed at a hospital in Paris in 1952. TCA overdose is a significant cause of fatal drug poisoning. As a result, quetiapin 150 mg toxicity often becomes apparent in the first hour after an overdose. TCAs can behave like class 1A antiarrhythmics, as such, they can theoretically terminate ventricular fibrillation, decrease cardiac contractility and increase collateral blood circulation to ischemic heart muscle. The paradoxical observation of a sedative inducing mania led to testing with depressed patients. Side effects may also be enhanced by other drugs that have antimuscarinic properties. Die Resorption erfolgt nahezu vollständig und unabhängig von der Nahrungsaufnahme. Escitalopram-Konzentration. Die Demethylierung von Escitalopram wird hauptsächlich über CYP2C19 vermittelt. Additionally, it is a serious problem in the pediatric population due to their inherent toxicity[27] and the availability of these in the home when prescribed for bed-wetting and depression. The TCAs were developed amid the "explosive birth" of psychopharmacology in the early 1950s. Zu wenig Serotonin löst eine Depression aus, und deshalb müssen Betroffene Antidepressiva nehmen, die den Serotoninspiegel erhöhen: Dieser Mythos hält sich seit Jahrzehnten hartnäckig. Initially, gastric decontamination of the patient is achieved by administering, either orally or via a nasogastric tube, activated charcoal pre-mixed with water, which adsorbs the drug in the gastrointestinal tract (most useful if given within 2 hours of drug ingestion). Such side effects are relatively common and may include dry mouth, dry nose, blurry vision, lowered gastrointestinal motility or constipation, urinary retention, cognitive and/or memory impairment, and increased body temperature. A very small number of cases involving non-medical use of antidepressants have been reported over the past 30 years.[56] According to the US government classification of psychiatric medications, TCAs are "non-abusable"[57] and generally have low misuse potential.[58] Nonetheless, due to their atypical mechanism of action, amineptine and tianeptine (dopamine reuptake inhibition and μ-opioid receptor agonism, respectively) are the two TCAs with the highest addiction and misuse potential. Inhaltsstoffe mit Wirkstoff-Informationen und Präparate-Zuordnung. Die Hauptmetaboliten haben eine signifikant längere Halbwertszeit. Apotheker und andere medizinische Fachkreise. In the brain, acetylcholine is involved in learning and memory. Escitalopram sollte während der Schwangerschaft nur angewendet werden, wenn es unbedingt notwendig ist und auch nur nach sorgfältiger Nutzen-Risiko-Abwägung. Sensory and movement disturbances have also been reported, including imbalance, tremors, vertigo, dizziness, and electric-shock-like experiences in the brain, often described by people who have them as "brain zaps". Antidepressants in general may produce withdrawal.

The TCAs show efficacy in the clinical treatment of a number of different types of chronic pain, notably neuralgia or neuropathic pain and fibromyalgia.[15][16] The precise mechanism of action in explanation of their analgesic efficacy is unclear, but it is thought that they indirectly modulate the opioid system in the brain downstream via serotonergic and noradrenergic neuromodulation, among other properties.[17][18][19] They are also effective in migraine prophylaxis, though not in the instant relief of an acute migraine attack. Tolerance to these adverse effects of these drugs often develops if treatment is continued. Postnatal adaptation syndrome (PNAS) (originally called "neonatal behavioral syndrome", "poor neonatal adaptation syndrome", or "neonatal withdrawal syndrome") was first noticed in 1973 in newborns of mothers taking antidepressants; symptoms in the infant include irritability, rapid breathing, hypothermia, and blood sugar problems. Danach wird auf 10 mg täglich gesteigert. The TCAs are used primarily in the clinical treatment of mood disorders such as major depressive disorder (MDD), dysthymia, and treatment-resistant variants. Tetracyclic antidepressants (TeCAs), which contain four rings of atoms, are a closely related group of antidepressant compounds. TCAs were discovered in the early 1950s and were marketed later in the decade.[1] They are named after their chemical structure, which contains three rings of atoms. Es ist davon auszugehen, dass Escitalopram in die Muttermilch übergeht. Die Profi-Suche bietet genauere und erweiterte Suchoptionen nach Präparaten. Sowohl die Muttersubstanz als auch die Metaboliten werden zum Teil als Glucuronide eliminiert. It was not originally targeted for the treatment of depression. There are two major groups of TCAs in terms of chemical structure, which most, but not all, TCAs fall into.[50][51][52] The groupings are based on the tricyclic ring system.[50][51][52] They are the dibenzazepines (imipramine, desipramine, clomipramine, trimipramine, lofepramine) and the dibenzocycloheptadienes (amitriptyline, nortriptyline, protriptyline, butriptyline).[50][51] Minor TCA groups based on ring system include the dibenzoxepins (doxepin), the dibenzothiepines (dosulepin), and the dibenzoxazepines (amoxapine).[50][51] In addition to classification based on the ring system, TCAs can also be usefully grouped based on the number of substitutions of the side chain amine.[52][53] These groups include the tertiary amines (imipramine, clomipramine, trimipramine, amitriptyline, butriptyline, doxepin, dosulepin) and the secondary amines (desipramine, nortriptyline, protriptyline).[52][53] Lofepramine is technically a tertiary amine, but acts largely as a prodrug of desipramine, a secondary amine, and hence is more similar in profile to the secondary amines than to the tertiary amines.[53] Amoxapine does not have the TCA side chain and hence is neither a tertiary nor secondary amine, although it is often grouped with the secondary amines due to sharing more in common with them.[54] In 2021, a new method was developed at the Institute for Bioengineering of Catalonia for designing photochromic analogs of tricyclic drugs via (1) isosteric replacement of the two-atom bridge between the aromatic systems with an azo group and (2) opening of the central ring. They are also used in the treatment of a number of other medical disorders, including cyclic vomiting syndrome (CVS) and anxiety disorders such as generalized anxiety disorder (GAD), social phobia (SP) also known as social anxiety disorder (SAD), obsessive-compulsive disorder (OCD), and panic disorder (PD), post-traumatic stress disorder (PTSD), body dysmorphic disorder (BDD), eating disorders like anorexia nervosa and bulimia nervosa, certain personality disorders such as borderline personality disorder (BPD), neurological disorders such as attention-deficit hyperactivity disorder (ADHD),[5] Parkinson's disease[6] as well as chronic pain, neuralgia or neuropathic pain, and fibromyalgia, headache, or migraine, smoking cessation, tourette syndrome, trichotillomania, irritable bowel syndrome (IBS), interstitial cystitis (IC), nocturnal enuresis (NE),[7] narcolepsy, insomnia, pathological crying and/or laughing, chronic hiccups, ciguatera poisoning, and as an adjunct in schizophrenia. Obwohl für Escitalopram keine Beeinträchtigung der kognitiven Funktionen und der psychomotorischen Leistungsfähigkeit nachgewiesen werden konnte, kann jedes Psychopharmakon die Urteilskraft und Geschicklichkeit beeinträchtigen. The first TCA reported for the treatment of depression was imipramine, a dibenzazepine analogue of chlorpromazine code-named G22355. Smith Kline & French Laboratories.

Escitalopram ist das aktive S-Enantiomer von Citalopram. In the event of a known or suspected overdose, medical assistance should be sought immediately. Der Wirkstoff Escitalopram ist ein Antidepressivum aus der Klasse der Serotonin-Wiederaufnahme-Inhibitoren (SSRI) und wird angewendet zur Behandlung von Depressionen, Angst-, Panik- und Zwangsstörungen. In addition to their reuptake inhibition, many TCAs also have high affinity as antagonists at the 5-HT2[33] (5-HT2A[34] and 5-HT2C[34]), 5-HT6,[35] 5-HT7,[36] α1-adrenergic,[33] and NMDA receptors,[37] and as agonists at the sigma receptors[38] (σ1[38] and σ2[39]), some of which may contribute to their therapeutic efficacy, as well as their side effects.[40] The TCAs also have varying but typically high affinity for antagonising the H1[33] and H2[41][42] histamine receptors, as well as the muscarinic acetylcholine receptors.[33] As a result, they also act as potent antihistamines and anticholinergics. Der Stickstoff kann außerdem zum N-Oxid-Metaboliten oxidiert werden. The first trial of imipramine took place in 1955 and the first report of antidepressant effects was published by Swiss psychiatrist Roland Kuhn in 1957.[3] Some testing of Geigy's imipramine, then known as Tofranil, took place at the Münsterlingen Hospital near Konstanz.[4] Geigy later became Ciba-Geigy and eventually Novartis. Antidepressant discontinuation symptoms were first reported with imipramine, the first tricyclic antidepressant (TCA), in the late 1950s, and each new class of antidepressants has brought reports of similar conditions, including monoamine oxidase inhibitors (MAOIs), SSRIs, and SNRIs. Nebenwirkungen treten vor allem in der ersten oder zweiten Behandlungswoche mit Escitalopram auf und nehmen normalerweise bei fortgesetzter Behandlung an Intensität und Häufigkeit ab. Weitere Informationen sind der jeweiligen Fachinformation zu entnehmen. Die Verstoffwechslung von Escitalopram erfolgt in der Leber zu demethylierten und didemethylierten Metaboliten, die beide pharmakologisch aktiv sind. Other side effects may include drowsiness, anxiety, emotional blunting (apathy/anhedonia), confusion, restlessness, dizziness, akathisia, hypersensitivity, changes in appetite and weight, sweating, muscle twitches, weakness, nausea and vomiting, hypotension, tachycardia, and rarely, irregular heart rhythms. Drugs that inhibit cytochrome P450 (for example cimetidine, methylphenidate, fluoxetine, antipsychotics, and calcium channel blockers) may produce decreases in the TCAs' metabolism, leading to increases in their blood concentrations and accompanying toxicity.[29] The major factor that distinguishes SSRI's amongst one another is the inhibition of select CYP enzymes .[29] Drugs that prolong the QT interval including antiarrhythmics such as quinidine, the antihistamines astemizole and terfenadine, and some antipsychotics may increase the chance of ventricular dysrhythmias. Escitalopram gehört zur Wirkstoffgruppe der Serotonin-Wiederaufnahme-Inhibitoren (SSRI). Stunden und die orale Plasmaclearance etwa 0,6 l/min. In the late 1990s, some investigators thought that the fact that symptoms emerged when antidepressants were discontinued might mean that antidepressants were causing addiction, and some used the term "withdrawal syndrome" to describe the symptoms. With the exception of the sigma receptors, the TCAs act as antagonists or inverse agonists of the receptors and as inhibitors of the transporters. New research has also revealed compelling evidence of a link between long-term use of anticholinergic medications like TCAs and dementia.[22] Although many studies have investigated this link, this was the first study to use a long-term approach (over seven years) to find that dementias associated with anticholinergics may not be reversible even years after drug use stops.[23] Anticholinergic drugs block the action of acetylcholine, which transmits messages in the nervous system.

Stimmungsaufhellende antidepressiva

Nach Mehrfachgabe betragen die Konzentrationen der Demethyl- und der Didemethyl-Metaboliten im Allgemeinen durchschnittlich 28 bis 31% bzw. Bis zum Ansprechen auf die Behandlung sind in der Regel 2 bis 4 Wochen erforderlich. Die empfohlene Anfangsdosis bei der Behandlung der Panikstörung mit oder ohne Agoraphobie beträgt in der ersten Behandlungswoche 5 mg. Der Wirkstoff Escitalopram ist in Form von Filmtabletten und als Tropfen zum Einnehmen auf dem deutschen Markt zugelassen. For many years the TCAs were the first choice for pharmacological treatment of major depression. TCAs may enhance the response to alcohol and the effects of barbiturates and other CNS depressants. Je nach individuellem Ansprechen des Patienten kann die Dosis auf maximal 20 mg täglich erhöht werden. Dibenzazepine derivatives are described in U.S. Although they are still considered to be highly effective, they have been increasingly replaced by antidepressants with an improved safety and side effect profile, such as the SSRIs and other newer antidepressants such as the novel reversible MAOI moclobemide.
