Alan, Celexa was first marketed in 1998. It took a number of years before that to develop & test it. Separation of racemic mixtures like citaprolam (Celexa) is a fairly new technology. There's more than one way of separating mixtures depending on what the compound is. It's still being finely honed to come up with cheaper ways of doing it. They could NOT have separated Celexa from the start as you suggest. Doesn't mean that drug companies aren't on the band wagon in a big way now, seeing it as a means to boost sales, but it's good to keep all information accurate.

An interesting story from Chemical & Engineering News on the marketing of racemic drugs & the interest by pharmaceutical companies.
