Preclinical assessment refers to the evaluation of new drugs, medical devices, or treatments in a laboratory setting before they are tested in human clinical trials. This process involves conducting experiments on animals or cell cultures to assess the safety, efficacy, and potential side effects of the proposed intervention. Preclinical assessment is an essential step in the drug development process as it helps researchers to identify promising treatments and screen out those that are unlikely to be effective or safe for human use. Additionally, preclinical assessment also provides valuable data that can inform the design of future clinical trials.
