Drug distribution

Okay kiddo, so you know how when you get a cold your mom gives you medicine to make you feel better? Well, that medicine is made up of tiny parts called molecules. These molecules need to get from the medicine to different parts of your body to help make you feel better.

Imagine your body is like a city and the molecules are like little delivery trucks. These little trucks need to drive all around the city to deliver the medicine to different parts.

But there are some parts of your body that are harder to get to than others. It's like trying to deliver a package to a house at the top of a huge hill. Some delivery trucks might be able to make it up the hill easily, but others might struggle.

So, the medicine makers plan that when the medicine goes into your body, it will be distributed evenly to all the different parts. This is like having a lot of little trucks that are all different sizes, so they can each reach every part of the city.

But sometimes the medicine needs to go to a specific part of your body. Like, if you have a headache, you might take a medicine that needs to go specifically to your head. This is like having a special delivery truck just for that one house at the top of the hill.

So, the medicine makers design the medicine to target certain parts of your body. They make sure that the molecules in the medicine will only go to that part, like a GPS programmed to only go to one specific address.

So, that's how drug distribution works. The medicine gets broken down into tiny molecules that travel all throughout your body like little delivery trucks, and the makers design it to get to the right spot to help you feel better.
