Question: is citalopram the same as citalopram?
Answer: Citalopram is a mixture of two stereo-isomers: R-citalopram and S-citalopram. Stereo-isomers are compounds that have the same chemical formula but differ only in their arrangement of atoms. Escitalopram contains only one isomer, S-citalopram. Lexapro is also FDA approved to treat generalized anxiety disorder.
