it's possible they're different concentrations. (most american preparations are 100 mg/mL.) although it wouldn't matter if you dried it out.
if they're not, THEY ARE IDENTICAL, never let anyone tell you otherwise. all bottles labeled "ketamine hydrochloride injection, USP" contain exactly the same active ingredient.
