How are Medicines Discovered & Developed?

Medicines are discovered and developed like solving a puzzle to make someone feel better.

Imagine you have a toy that's broken, and you want it to work again. Scientists do something similar with medicines, they look for the right piece (the medicine) that fits the problem (like sickness or pain).

It all begins with observation, scientists notice that some people feel better after taking certain things, like candy or a special drink. They start asking questions: What makes this work? Can we make it better?

They then test these ideas in labs, using tiny models (like mini versions of the body) to see if the medicine works.

Once scientists know a medicine works in the lab, they try it on people. This is like trying out a new game with friends, some might love it, others might not. Scientists watch how people react and make changes until the medicine becomes strong and safe for everyone.

After many tests, if everything goes well, the medicine gets approved and finally reaches the stores so people can use it to feel better!
