Preclinical testing involves?

Preclinical testing involves?

• A. Human clinical trials.
• B. Post-marketing surveillance.
• C. In-vitro and animal testing before human trials to evaluate toxicity, PK/ADME, safety, and formulation.
• D. Regulatory approval.

Answer: (C)

Preclinical testing consists of laboratory and animal studies conducted before testing in humans. The aim is to characterize safety and how the drug behaves in the body, and to develop a workable formulation. In vitro experiments and animal studies evaluate toxicity, determine pharmacokinetics and ADME (absorption, distribution, metabolism, and excretion), assess overall safety margins, and help optimize the formulation and dosing strategy for first-in-human trials. These data underpin regulatory filings and the design of initial clinical studies. Human clinical trials come after this stage, post-marketing surveillance occurs after a product is approved, and regulatory approval is the authorization granted after reviewing clinical data. The preclinical focus is on predicting human safety and pharmacology from non-human systems.
