When did zoloft come on the market?

When did Zoloft (sertraline) first go on the market?

Zoloft (sertraline) was approved by the U.S. Food and Drug Administration (FDA) in 1991 and launched on the market in 1992. [1]

Was it available in the U.S. in 1991 or 1992?

FDA approval came in 1991, but the product reached the market in 1992, which is why both years show up in different references. [1]

Where can I verify the launch/approval timing?
