What does preclinical mean in drug development?

• A. The testing in animals before humans
• B. The testing in humans after animals
• C. In vitro testing only
• D. Post-market surveillance

Answer: (A)

Preclinical means studies done before any testing in humans, usually involving animals and laboratory experiments to assess safety, dosing, toxicity, and how the drug behaves in the body. This stage provides the data regulators require to approve starting human trials, and it includes in vitro work as part of building the safety and pharmacology profile. It is not testing in humans, not limited to in vitro work, and not post-market surveillance, which happens after a drug is approved.
