Escitalopram oxalate Chemical Properties,Usage,Production
Description
Escitalopram was launched as Cipralex? in Switzerland, Sweden and UK for the treatment of depression and panic disorder. It is the S-enantiomer version of the selective serotonin reuptake inhibitor (SSRI) citalopram approved in 1989. It can be obtained from 5cyanophthalide by successive reactions with 4-fluorophenyl magnesium bromide and 3-(dimethylamino)propyl magnesium chloride. The resulting racemic diol can be resolved by several routes such as crystallization with a chiral acid. Finally, a two step cyclisation procedure affords escitalopram. Escitalopram is twice as effective as the racemate and over 100 fold more potent than the R-enantiomer in inhibiting the 5HT reuptake in vivo in rat brain synaptosomes. Moreover, it exhibits higher selectivity for the human serotonin transporter relative to the noradrenaline or dopamine transporters than any other currently available SSRl’s. In the mouse forced swim test, the duration of immobility (which reflects antidepressant activity) for escitalopram was comparable to citalopram and greater than (R)-citalopram. Clinical trials in patients with panic disorders or depression have shown that escitalopram has a clinically relevant and significant effect. Additionally, it has a faster onset of antidepressant action than citalopram. Escitalopram has linear pharmacokinetics, with a long half-life (27-32 h). It is extensively metabolized in the liver via cytochromes P450 to S(+)-desmethyl and S(+)-didesmethyl citalopram. However, it has been shown to be a weak or negligible inhibitor of CYP450 drugmetabolizing enzymes in vitro. Escitalopram is well tolerated with nausea being the most common side effect.

General Description
Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards.
Escitalopram Oxalate, a highly selective serotonin re-uptake inhibitor antidepressant, is a pure S-enantiomer of the racemic, bicyclic pthalates derivatives of citalopram. It is mainly developed for the treatment of depression and anxiety disorders.
Biochem/physiol Actions
Escitalopram is a selective serotonin reuptake inhibitor (SSRI), the S-enantiomer and eutomer of citalopram.
Mechanism of action
Escitalopram is the S-enantiomer of citalopram and is the most selective of SSRIs. SSRIs' mechanism of action is exerted by binding to the sodium-dependant serotonin transporter protein (SERT) located in the presynaptic neuron. SERT works by re-uptaking serotonin from the synaptic cleft to the presynaptic neuron. When SERT is inactivated by escitalopram, this increases the amount of serotonin in the synaptic cleft.
Side effects
The main side effect of escitalopram include: Nausea, dry mouth, trouble sleeping, constipation, tiredness, drowsiness, dizziness, and increased sweating may occur.
Synthesis
The synthesis of escitalopram was carried out in several different routes [30-33]. 5-Cyanophthalide (72) was treated with Grignard reagent 73 at 0??C to provide intermediate 75 which was reacted in situ with another Grignard reagent 76 to afford the diol in a one-pot process. Racemic diol 77 was resolved using (+)-p-toluoyltartaric acid to afford desired S isomer 78 in 55% yield. The ring closure reaction was carried out at 0??C using methanesulfonyl chloride in toluene to furnish escitalopram (7) in 60% yield.
