CELEXA, 40, MG, SSRI, Citalopram
Celexa® (citalopram HBr) is an orally administered selective serotonin reuptake inhibitor (SSRI) with a chemical structure unrelated to that of other SSRIs or of tricyclic, tetracyclic, or other available antidepressant agents. Citalopram HBr is a racemic bicyclic phthalane derivative designated (±)-1-(3-dimethylaminopropyl)-1-(4-fluorophenyl)-1,3-dihydroisobenzofuran-5-carbonitrile, HBr SSRI medications change brain chemistry by increasing the neurotransmitter, Serotonin. This increase is accomplished by blocking the process (which is called reuptake) by which Serotonin is eliminated. They are the most popular class of antidepressant drugs that are prescribed because of their lower adverse effects and safety (higher toxic dose) compared to other types of depression medicine. SSRIs are also considered depression anxiety medications because they treat anxiety among other mental conditions. Overall, these anti-depressant drugs are not prescribed for treating manic depression (which is characterized by episodes of depression and/or extreme elevated mood or irritability).
