440-17-5CN1CCN(CCCN2c3ccccc3Sc3ccc(C(F)(F)F)cc32)CC1.Cl.ClBXDAOUXDMHXPDI-UHFFFAOYSA-NTrifluoperazine Hydrochloride is the hydrochloride salt of trifluoperazine, a phenothiazine derivative and a dopamine, alpha-adrenergic, and anticholinergic antagonist with antipsychotic, anxiolytic, and antiemetic activities. Trifluoperazine blocks central dopamine receptors, which may prevent or mitigate delusions and hallucinations caused by an excess of dopamine; dopamine blockade in the chemoreceptor trigger zone (CTZ) may result in an antiemetic effect. This agent binds to central adrenergic receptors, which may result in anxiolytic effects. Trifluoperazine also functions as a calmodulin inhibitor, elevating cytosolic calcium.

Treatment is essentially symptomatic and supportive. Early gastric lavage is helpful. Keep patient under observation and maintain an open airway, since involvement of the extrapyramidal mechanism may produce dysphagia and respiratory difficulty in severe overdosage. Do not attempt to induce emesis because a dystonic reaction of the head or neck may develop that could result in aspiration of vomitus. Extrapyramidal symptoms may be treated with anti-parkinsonism drugs, barbiturates or Benadryl. See prescribing information for these products. Care should be taken to avoid increasing respiratory depression. If administration of a stimulant is desirable, amphetamine, dextroamphetamine or caffeine with sodium benzoate is recommended. Stimulants that may cause convulsions (e.g., picrotoxin or pentylenetetrazol) should be avoided. If hypotension occurs, the standard measures for managing circulatory shock should be initiated. If it is desirable to administer a vasoconstrictor, Levophed and Neo-Synephrine are most suitable. Other pressor agents, including epinephrine, are not recommended because phenothiazine derivatives may reverse the usual elevating action of these agents and cause a further lowering of blood pressure.

Drugs used to prevent NAUSEA or VOMITING.
Agents that control agitated psychotic behavior, alleviate acute psychotic states, reduce psychotic symptoms, and exert a quieting effect. They are used in SCHIZOPHRENIA; senile dementia; transient psychosis following surgery; or MYOCARDIAL INFARCTION; etc. These drugs are often referred to as neuroleptics alluding to the tendency to produce neurological side effects, but not all antipsychotics are likely to produce such effects. Many of these drugs may also be effective against nausea, emesis, and pruritus.
Drugs that bind to but do not activate DOPAMINE RECEPTORS, thereby blocking the actions of dopamine or exogenous agonists. Many drugs used in the treatment of psychotic disorders (ANTIPSYCHOTIC AGENTS) are dopamine antagonists, although their therapeutic effects may be due to long-term adjustments of the brain rather than to the acute effects of blocking dopamine receptors. Dopamine antagonists have been used for several other clinical purposes including as ANTIEMETICS, in the treatment of Tourette syndrome, and for hiccup. Dopamine receptor blockade is associated with NEUROLEPTIC MALIGNANT SYNDROME.
説明Trifluoperazine (TFP) is a phenothiazine compound with anti-adrenergic and anti-dopaminergic actions typical of antipsychotic agents. It antagonizes adrenergic receptors, with selectivity for α1 over the α2 subtypes (Kis = 24, 653, 163, and 391 nM for α1A, α2A, α2B, and α2C, respectively). TFP binds with much higher affinity to the dopamine D2-like receptor (Kd = 0.96 nM) compared to the dopamine D4-like and the serotonin 5-HT2A receptors (Kds = 44 and 135 nM, respectively). Furthermore, TFP antagonizes calmodulin (CaM) and alters the calcium-binding properties of calsequestrin (CSQ). TFP has been shown to activate type-2 ryanodine receptors independently of its CaM and CSQ activity.

Trifluoperazine blocks postsynaptic mesolimbic dopaminergic D1 and D2 receptors in the brain; depresses the release of hypothalamic and hypophyseal hormones and is believed to depress the reticular activating system thus affecting basal metabolism, body temperature, wakefulness, vasomotor tone, and emesis.

使用Trifluoperazine dihydrochloride has been used as a calmodulin kinase antagonist in cultured Aplysia californica neurons. Trifluoperazine dihydrochloride has also been used as a PMCA inhibitor in mouse duodenal tissues to block the transcellular active calcium flux.
一般的な説明Trifluoperazinehydrochloride, 10-[3-(4-Methyl-1-piperazinyl)propyl-[2-(trifluoromethyl)phenothiazine dihydrochloride (Stelazine).The absorption of trifluoperazine is erratic and variable andit is widely distributed into tissues. The excretion of trifluoperazineoccurs 50% via kidneys and the other 50% isthrough enterohepatic circulation. The metabolism and druginteractions of trifluoperazine are the same as with the otherphenothiazines. Trifluoperazine does not show any specificdrug interactions. Trifluoperazine is indicated for the managementof schizophrenia and short-term treatment ofnonpsychotic anxiety.
純化方法Recrystallise the salt from absolute EtOH, filter the crystals, dry them in vacuo and store them in tightly stoppered bottles because it is hygroscopic. It is soluble in H2O but insoluble in *C6H6, Et2O and alkaline aqueous solution. It has UV at 258 and 307.5nm (log 4.50 and 3.50) in EtOH (neutral species). [Craig max et al. J Org Chem 22 709 1957.] It is a calmodulin inhibitor [Levene & Weiss J Parmacol Exptl Ther 208 454 1978] and is a psychotropic agent [Fowler Arzneim.-Forsch 27 866 1977]. [Beilstein 27 III/IV 1353.]
