Final answer:
The purpose of a pre-clinical trial is to evaluate the pharmacokinetic properties and safety profile of a new drug before it is tested on humans in clinical trials.
Step-by-step explanation:
The purpose of a pre-clinical trial is to evaluate the pharmacokinetic properties and safety profile of a new drug before it is tested on humans in clinical trials.
During the pre-clinical trial, scientists conduct laboratory and animal studies to assess the pharmacokinetics and toxicokinetics of the drug, as well as its potential side effects.
This information helps researchers determine whether the drug is safe for further development and provides important data for designing and planning the subsequent clinical trials.
