So, how many milligrams of the fumarate equivalent is contained in each milliliter of the solution? That's all I'm trying to determine. Thanks

Thanks for the reply, but that doesn't really address my question. Based on the label for this particular preparation, how many milligrams of Ketotifen Fumarate are contained in each milliliter?

My mother is taking an antihistamine preparation containing Ketotifen. I am trying to determine how many milligrams of Ketotifen are contained in each milliliter of the preparation. Here is a pic of the package, showing the concentrations: Using the Ketotifen Fumarate concentration of 0.035%, my calculations say there are 3.5 milligrams in each milliliter of the preparation. Can someone verify this, or give me the correct level? I know this is pretty basic, sorry for that, but it's been a long time since I studied chemistry! This is related to a serious health matter, so if someone could check this for me, I sure would appreciate it! TIA Dan
