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] The antidepressant effects may take one to four weeks to occur. [7]
The pharmacology of antidepressants is not entirely clear.. The earliest and probably most widely accepted scientific theory of antidepressant action is the monoamine hypothesis (which can be traced back to the 1950s), which states that depression is due to an imbalance (most often a deficiency) of the monoamine neurotransmitters (namely serotonin, norepinephrine and dopamine). [1]
For example, Celexa is a mixture of a left-handed and right-handed version of the same compound ("citalopram"), but only the left-handed version ("es-citalopram") is biologically active. Lexapro, the "me too" drug released several years after Celexa thus extending the patent life, is a purified form of just the left-handed version (the "es" in ...
[181] [182] Discontinuation effects appear to be less for fluoxetine, perhaps owing to its long half-life and the natural tapering effect associated with its slow clearance from the body. One strategy for minimizing SSRI discontinuation symptoms is to switch the patient to fluoxetine and then taper and discontinue the fluoxetine.
Most SNRIs function alongside primary metabolites and secondary metabolites in order to inhibit reuptake of serotonin, norepinepherine, and marginal amounts of dopamine. For example, venlafaxine works alongside its primary metabolite O -desmethylvenlafaxine to strongly inhibit serotonin and norepinephrine reuptake in the brain.
For example, is citalopram ED more likely to happen than Prozac intimate dysfunction? Intimate side effects like ED are known to occur with many antidepressants, including the following common ...
