• Verwenden

  Antidepressant;5-HT transport inhibitor

• Verwenden

  Tricyclic antidepressant; inhibits the serotonin and norepinephrine transporters. Has little effect on the dopamine transporter

• Verwenden

  Imipramine hydrochloride is used as a serotonin uptake inhibitor. It mainly used in the treatment of major depression and enuresis (inability to control urination). It has also been evaluated for use in panic disorder.

• Manufacturing Process

  20 parts of imino dibenzyl are dissolved in 100 parts by volume of absolutely dry benzene. A suspension of 4 parts NaNH2 in 50 parts by volume of absolute benzene are then added dropwise at 50° to 60°C after which the mixture is boiled for an hour under reflux. 13 parts of 3-dimethylamino n_x0002_propyl chloride are then added dropwise at 40° to 50°C and the mixture is boiled for 10 hours under reflux. After cooling, the benzene solution is thoroughly washed with water, whereupon the basic constituents are extracted with dilute hydrochloric acid.
  The hydrochloric extract is then made alkaline and the separated base is extracted with ether. After drying, the solvent is evaporated and the residue is distilled in the high vacuum, whereby the N-(3-dimethylaminopropyl)-imino dibenzyl passes over at a temperature of 160°C under 0.1 mm pressure. The chlorohydrate with a melting point of 174° to 175°C is obtained therefrom with alcoholic hydrochloric acid.

• Allgemeine Beschreibung

  Imipramine hydrochloride, 5-[3-(dimethylamino)propyl]-10,11-dihydro-5H-dibenz[b,f]azepine monohydrochloride(Tofranil), is the lead compound of the TCAs. It is also a closerelative of the antipsychotic phenothiazines (replace the10–11 bridge with sulfur, and the compound is the antipsychoticagent promazine). It has weaker D₂ postsynaptic blockingactivity than promazine and mainly affects amines (5-HT,NE, and DA) via the transporters. As is typical of dimethylaminocompounds, anticholinergic and sedative (central H₁block) effects tend to be marked. The compound per se has a tendency toward a high 5-HT-to-NE uptake block ratio andprobably can be called a serotonin transport inhibitor(SERTI). Metabolic inactivation proceeds mainly by oxidativehydroxylation in the 2-position, followed by conjugationwith glucuronic acid of the conjugate. Urinary excretion predominates(about 75%), but some biliary excretion (up to25%) can occur, probably because of the large nonpolargrouping. Oxidative hydroxylation is not as rapid or completeas that of the more nucleophilic ring phenothiazine antipsychotics;consequently, appreciable N-demethylation occurs,with a buildup of norimipramine (or desimipramine).

• Biologische Aktivität

  imipramine (hydrochloride) is a tricyclic antidepressant and is mainly used in the treatment of major depression and enuresis [1].antidepressants are antagonists of many neurotransmitter receptors in human brain [3].imipramine is the first tricyclic antidepressant that acts mainly as an inhibitor of serotonin and norepinephrine transporters [2]. in radioligand binding assays, imipramine inhibited serotonin and norepinephrine transporters with kd values of 1.4 and 37 nm, respectively [2]. imipramine is also inhibited histamine h1 receptor, muscarinic acetylcholine receptor and α1-adrenergic receptor with kd values of 37, 46, and 32 nm, respectively [4].in rodents, imipramine abolished the depressive syndrome produced by the acute administration of reserpine. imipramine also possessed central anticholinergic activity and attenuate the activity of the centrally acting muscarinic agents tremorine and oxotremorine. imipramine inhibited the presynaptic uptake of na and 5-ht, and relatively weak against da [1].

• Biochem/physiol Actions

  Tricyclic antidepressant; inhibits the serotonin and norepinephrine transporters with Kis of 7.7 nM and 67 nM, respectively. Has little effect on the dopamine transporter (Ki = 25 μM).

• Clinical Use

  The demethylated metabolite is less anticholinergic, lesssedative, and more stimulatory and is a SNERI.Consequently, a patient treated with imipramine has twocompounds that contribute to activity. Overall, the effect isnonselective 5-HT versus NE reuptake.

• Sicherheitsprofil

  Human poison by ingestion. An experimental poison by ingestion, intravenous, subcutaneous, and intraperitoneal routes. An experimental teratogen. Human systemic effects by ingestion: sleep, somnolence, convulsions, muscle contraction or spasticity, coma, blood pressure decrease, dyspnea (difficulty in breathing), paresthesia (abnormal sensations), and kidney changes. Experimental reproductive effects. Mutation data reported. Used in the treatment of depression. When heated to decomposition it emits very toxic fumes of NO, and HCl. See also DIAZEPAM.

• Veterinary Drugs and Treatments

  In dogs and cats, imipramine has been used to treat cataplexy and urinary incontinence. In horses, imipramine has been used to treat narcolepsy and ejaculatory dysfunction (no parenteral dosage forms available).

• Stoffwechsel

  Imipramine is extensively demethylated by first-pass metabolism in the liver, to its primary active metabolite, desipramine (desmethylimipramine). Paths of metabolism of both imipramine and desipramine include hydroxylation and N-oxidation.
  About 80% is excreted in the urine and about 20% in the faeces, mainly in the form of inactive metabolites. Urinary excretion of unchanged imipramine and of the active metabolite desipramine is about 5% and 6% respectively. Only small quantities of these are excreted in the faeces.
