ELI5: Explain Like I'm 5

Bioequivalence

Okay kiddo, imagine you have two different candies that taste very similar. One candy is called Candy A and the other is Candy B. Now, you want to know if these two candies are actually the same or if one candy has more sugar than the other.

Scientists do the same thing with medicines. They compare two medicines to see if they work the same way in our bodies. This is called bioequivalence.

Basically, the scientists give the same amount of medicine A to one group of people and the same amount of medicine B to another group of people. Then, they check to see if both groups have the same amount of medicine in their body and if they have the same effect.

If the two medicines are bioequivalent, it means they work the same way in our bodies and we can use either medicine to treat the same illness.

So just like you want to know that you're getting the same amount of candy no matter which one you pick, scientists want to be sure that we're getting the same medicine no matter which company makes it or which version of the medicine we take.
