Lexapro Vs. Celexa for Anxiety

Save

Celexa and Lexapro are medications frequently used in the treatment of depression and anxiety. Since the latter was created from the former, there are many similarities between the two. There are also certain differences, however, that may result in a patient choosing one over the other.

SSRIs

Both Celexa and Lexapro are SSRIs, or serotonin reuptake inhibitors. Drugs in this category work by preventing the reabsorption of serotonin so that serotonin levels increase, positively affecting anxiety and/or depression symptoms that are created by imbalances in this chemical.

Celexa

First to be developed between the two medications, Celexa is a mixture of citalopram’s R and S enantiomers, which are isomers that are mirror-images of each other. Despite being approved for the treatment of depression as opposed to anxiety, depression patients with anxiety symptoms have found relief with Celexa.

Lexapro

Lexapro was developed through the isolation of the S enantiomer in Celexa; this enantiomer has been proven to be more active than the R enantiomer that Celexa also includes. It has been called a “cleaner, improved version of Celexa” by scientists and researchers. In 2002, a study by Forest Laboratories determined that Lexapro was successful in reduced symptoms in persons with panic disorder, generalized anxiety disorder and social anxiety disorder.

Effectiveness

While individual patients respond differently to different medications, Lexapro has proven to have the same effects of decreasing symptoms of depression and anxiety as Celexa, but at a lower dose. For some patients, however, Celexa produces better results. It is important to discuss medication possibilities with your doctor before starting any drug regimen.
