Labetalol patented year?

What year was labetalol patented?

I can’t answer this from the information provided here. The patent “year” for labetalol depends on which patent record you mean (for example, the original compound patent vs. later formulation/process patents), and the exact year varies by jurisdiction.

If you tell me which patent database or country you want (e.g., US FDA Orange Book, UK patent, European patent) or share a link/number, I can give the exact year.
