Preclinical
Preclinical
Preclinical (pre-klin-i-kal) refers to the stage of research that occurs before a drug or procedure is tested on humans. It involves in-vitro (test tube or cell culture) and in-vivo (animal) testing to determine the safety and efficacy of a new drug or procedure.
Etymology
The term "preclinical" is derived from the prefix "pre-", meaning "before", and "clinical", which refers to the practice or observation of medicine. Thus, "preclinical" literally means "before the clinical stage".
