Anticholinergic dosage drug conversion

[X11400]

Does anyone know of an anticholinergic drug conversion chart that can be used to figure out equipotent dosages of drugs like Diphenhydramine or Promethazine?

That would be interesting, if not hard to get. I'm curious how much atropine a 50mg diphenhydramine is equivalent to.

Maybe the data isn’t available. Let’s see if @sekio has any info, they seem to be Neuropsychopharmacologists.
