Which of the following medications is marketed as Lexapro?

Lexapro is the brand name for escitalopram, which is a selective serotonin reuptake inhibitor (SSRI) commonly used for the treatment of anxiety disorders and major depressive disorder. Escitalopram works by increasing the levels of serotonin in the brain, which can improve mood and alleviate anxiety. Its efficacy and safety profile make it a popular choice among healthcare providers for managing these conditions.

The other medications listed have different chemical compositions and therapeutic uses. Vilazodone and vortioxetine are both also antidepressants, but they are not the same as escitalopram. Fluvoxamine is another SSRI, but it is marketed under a different name and prescribed for different conditions, primarily obsessive-compulsive disorder and social anxiety disorder. Thus, recognizing escitalopram as the active ingredient in Lexapro directly ties it to its brand's marketing and therapeutic purpose.
