I think it is a 50:50 mixture, but I can't be 100% sure because I don't know the synthesis of citalopram.
There are ways to favor one entantiomer over another but as is the case in nature, sometimes things aren't as clean as they ought to be. I did learn about a technique to make 98% of one enantiomer of one particular molecule, but it also made 2% of the other enantiomer, so it is possible to get a non 50:50 ratio.
