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
