Citalopram, sold under the brand name Celexa among others, is an antidepressant of the selective serotonin reuptake inhibitor (SSRI) class. [ 7 ] [ 10 ] It is used to treat major depressive disorder , obsessive compulsive disorder , panic disorder , and social phobia . [ 7 ]
MDMA/citalopram is a combination of the entactogen and monoamine releasing agent 3,4-methylenedioxymethamphetamine (MDMA; also known as midomafetamine or "ecstasy") and the selective serotonin reuptake inhibitor (SSRI) citalopram which is under development for the treatment of post-traumatic stress disorder (PTSD).
Serotonin. A serotonin reuptake inhibitor (SRI) is a type of drug which acts as a reuptake inhibitor of the neurotransmitter serotonin (5-hydroxytryptamine, or 5-HT) by blocking the action of the serotonin transporter (SERT).
Andersen et al. were able to generate a model of the (S)-citalopram binding site in human SERT by combining mutational analysis and comparative modeling where they found out that Asn-177 and Phe-341 where key determinants for (S)-citalopram potency and high affinity inhibition [47] in addition to Tyr-95, Asp-98, Ile-172 and Ser438 previously ...
The full mechanism of action for the anti-inflammatory effects of SSRIs is not fully known. However, there is evidence for various pathways to have a hand in the mechanism. One such possible mechanism is the increased levels of cyclic adenosine monophosphate (cAMP) as a result of interference with activation of protein kinase A (PKA), a cAMP ...
Celexa – an antidepressant of the SSRI class; Centrax – an anti-anxiety agent; Clozaril – atypical antipsychotic used to treat resistant schizophrenia; Concerta (methylphenidate) – an extended release form of methylphenidate
Evidence of the allosteric action of escitalopram on the serotonin transported is based on the observation that the R isomer of citalopram can decrease the potency and inhibit the effects of the S isomer, probably through an allosteric interaction between two distinct, non-overlapping binding sites for the two different isomers on the serotonin transporter.
Citalopram is a racemic mixture (50/50), and the inhibition of 5-HT reuptake by citalopram is primarily due to the (S)-enantiomer. [1] Citalopram has no or very low affinity for 5-HT 1a 5-HT 2a, dopamine D 1 and D 2, α 1-, α 2-, and β-adrenergic, histamine H 1, gamma aminobutyric acid (GABA), muscarinic cholinergic, and benzodiazepine ...
