> 'Celexa' 20mg is 10mg s-isomer and 10 mg r-isomer. The r-isomer is effectively inert as an SSRI or anything else. Celexa only works because of the 10mg s-isomer in it. 'Lexapro' is the 10mg s-isomer on its own. It's pretty hard and expensive to produce separately, and it's a funny thing to do when the r-isomer has virtually no pharmacological action at all.
