ELI5: Explain Like I'm 5

Mechanism of action

Mechanism of action is like explaining how a toy works. Just like how you need to know how to make a toy move, doctors and scientists need to know how a medicine works in our body.

Our body is made up of millions of tiny parts called cells. Each of these cells has a job to do. When we get sick, it means that some of these cells are not doing their job properly. Medicines help to fix this by telling our cells what to do.

However, different medicines work in different ways. Some medicines go directly to the cells and tell them what to do. Others can’t do this, so they need to work in a different way.

For example, some medicines work by blocking certain parts of the cells. Think of the cells like a building with doors and windows. If a medicine can block a door or window, this can help to stop the cells from doing what they shouldn’t be doing.

Other medicines work by changing the way our cells work together. When we get sick, it means that some cells are not communicating with each other in the right way. Medicines can help to fix this by changing the way cells talk to each other.

In summary, mechanism of action is how medicines work in our body to help fix cells that are not doing their job properly. It’s like telling cells what to do so that we can feel better!
