There are 5 stages of drug development: preclinical tests on cells and tissues; preclinical tests on live animals; clinical trials on human volunteers; clinical trials on patients and peer review.

Preclinical tests on cells and tissues:

Tests for efficiency
To see if it works in the way we want it to
Once it works in the way we want it to, we can move onto stage 2

Preclinical tests on live animals:

Tests for toxicity - is it harmful and how harmful is it
Gives us an idea of the dosage that tis needed
Tests for side affects in other parts of the body
Once we find out the correct dosage and no there are no harmful side affects in the animals, we can move onto stage 3
