Me-too compound

Okay, so imagine you're at school and your friend brings in a really cool toy that everyone is playing with. You might also want to have that same toy because it looks like a lot of fun. That's kind of like what a me-too compound is.

In science, when one company creates a medication that helps treat a certain illness, other companies might want to make a similar medication that does the same thing. These similar medications are called me-too compounds.

Just like you wanted the same toy your friend had, other companies want to make a similar medicine to what their competitors are making. But they also want to make it a little different so they can patent their own version and make money too.

So, me-too compounds are medicines that are very similar to other medicines that already exist, and are designed to do the same thing, but with some small differences that make them unique.
