Pharmaceutics is like going to the doctor and getting a medicine to make you feel better when you are sick.
Think of your body like a big city with lots of different neighborhoods. If some neighborhoods are sick or not feeling well, the doctor gives medicine to help fix that part of the city.
But medicine is not just a one-size-fits-all solution. Different types of medicine are made up of different ingredients that can help treat different kinds of illnesses or problems in your body. Just like how different tools are used by different workers to fix different parts of a house.
Pharmaceutics is the study of how to make medicine and how to make it the right way so that it helps you feel better without making you sick or causing other problems. Scientists who study pharmaceutics have to know a lot about different chemicals and how they work in the body, so they can create the best medicine for each person and each kind of sickness.
Just like how a good chef needs to know the right ingredients and how to combine them in the right way to make a delicious meal, scientists who study pharmaceutics need to know the right ingredients and how to combine them in the right way to make a medicine that helps you feel better.
