why is over-the-counter medicine based on age, but not weight?

most over the counter drugs are given for age, like, “2 pills per 24 hours for an adult, 1 pill for children over the age of 5” (something like that, I’m making up stuff).

but if drugs are diffused throughout the body, wouldn’t it be dependent on how much blood or tissue you have?

i mean, other things like alcohol work in that way. a 200# man and a 100# woman (or man) will get drunk at very different rates because it goes in the blood stream, and the 200# man maybe doesn’t have twice the blood volume but definitely a lot more.

meanwhile, tylenol or advil or ibuprofen are NOT dosed that way.
