How to find binding affnity

[Lightning-Nl]

I've been trying to find the binding affinities of Doxylamine, however, I cannot find them anywhere. So I thought I would ask of anyway to lookup Ki values of certain substances since typing "Doxylamine binding affinities" but it's not turning up anything.

Does anyone know how I can find these faster?

Thanks everyone.

If it's not in the PDSP database, you'd have to hit the literature.
